A close relative to other vining crops such as zucchini, melons and squash, the cucumber (Cucumis sativus) grows as an annual vine that does not survive frost. Its prickly stems clamber across the warm soil surface, producing yellow flowers that later become the familiar elongated fruits. Cucumbers are harvested when immature and small. Ripe cucumbers are large and plump with yellow skin, watery flesh and a bitter flavor. Plant cucumbers in a sunny garden plot two weeks after the last spring frost.
Types Cucumber plants spread and take up at least 25 square feet in the vegetable garden. Regular cucumbers often produce vines as long as 8 to 10 feet. Look at the seed packet or seedling label to learn the size of a mature plant. Bush cucumbers genetically develop much shorter stems and a compact overall plant size. Bush types make exceptional choices for small-sized gardens or for growing in containers. Either type may be grown on a trellis of an appropriate height to meet the mature length of the cucumber variety's stems. Planting Options Cucumbers may be grown in rows or hills. Row planting requires a long furrow that is 1/2 to 1 inch deep. Place seeds in the furrow spaced 12 inches apart. If you know the cucumber variety is very large growing, increase the spacing in the furrow to 18 to 36 inches apart. Another planting option for cucumber planting is sowing in hills. Make a wide basin about 10 inches wide and 1 inch deep. Place four or five seeds in the hill, each spaced 2 to 3 inches apart across the basin. Row Spacing Space additional straight rows of cucumbers at least 36 inches apart. Space hills 36 inches apart as well. Increase the distance among rows or hills up to 5 feet if the cucumber variety is known to grow large. Planting cucumbers too closely together causes leaves and vines to compete with each other for sunlight and reduces air circulation, which can encourage diseases. A dense matrix of cucumber vines also is difficult to navigate later when you walk through the patch to harvest fruits.
Vegetable Garden Planning Cucumbers do not cross-pollinate other vining crops in the garden, contrary to a common American garden myth. While you don't want crops growing into each other to create a tangle of vines, misshapen or poorly tasting cucumbers because of the pollen from nearby melons, squashes or zucchini plants. Only other cucumber varieties cross-pollinate -- all are the same botanical species. Cross-pollination does not affect cucumber fruit features or qualities, but it does yield hybridized seeds.

Green peppers are often referred to as sweet or bell peppers and come in many varieties. Pepper plants originated in tropical areas of the world where they grow as perennials. However, these tender warm-season vegetables are usually planted annually in summer vegetable gardens. Most pepper plants can take from 60 to 95 days from sowing to harvest, but you may not know that green peppers are actually not fully mature.
Temperature Requirements Most gardeners either start green peppers from seeds indoors seven to 10 weeks ahead of the proposed planting date or purchase green pepper transplants in the spring because of the temperatures required for growing these tender plants. The best temperature for growing peppers is no more than 80 degrees Fahrenheit during the day and not less than 60 degrees Fahrenheit at night. You must wait until the soil has warmed in the spring and there is no more chance of frost to plant peppers outside. Soil and Light Requirements Providing the ideal growing environment for the green pepper plants to develop and begin producing fruits starts with the planting location. Pepper plants prefer well-drained, moderately rich soil with a pH of 6.0 to 6.8. If possible, test your soil and alter it accordingly depending on the results. Amending the soil with 3 inches of organic matter is a common practice to enrich the soil without testing. Green peppers require full sunlight for more than six hours. Planting Green Peppers Only purchase healthy green pepper plants with three or more sets of leaves and no blossoms. Water the plants well before planting. Wait for a cloudy, cool day to place the transplants in the vegetable garden. Space the pepper transplants at least 18 inches apart and in rows at least 24 inches apart. Dig holes to plant them at the same depth and saturate the soil to remove any air pockets. Apply a starter fertilizer at half-strength to each plant.
Maintenance and Harvest Maintain the plants properly to ensure ideal growth and development occurs. Place a layer of mulch around the peppers to retain soil moisture and avert weeds or remove the weeds manually. Water the green pepper plants as needed to maintain moist but not soggy soil. Apply a vegetable fertilizer as directed while the plants are growing. Harvest the green peppers when the fruits have reached the size desired. Remove the peppers from the plants with a sharp knife or pruner to prevent damage. Varieties and Days to Harvest Sweet bell hybrid peppers change from green to red, including varieties like Bell Boy, Brigadier and Enterprise (71 days) and Palidin, Ranger and Sentry (75 days). Green ornamental peppers include NeMex Twilight and Thai Hot (70 days). Hot hybrid green peppers include Ancho Ranchero (70 days), Ancho Vila (80 days), Cherry Bomb (68 days), Grande and Super Chili (75 days). Open-pollinated sweet and hot green peppers include Queen (68 days), Valencia (70 days), Red Chill (82 days) and Ancho Gigantia (90 days).

Daikon radishes have long, fleshy taproots that are used for a variety of purposes. Daikon radishes are generally 2 to 4 inches in diameter and 6 to 20 inches long. The three distinct shapes are spherical, oblong and cylindrical. The uses for Daikon radishes are as varied as the shapes, colors and sizes they come in.
Origins of Daikon Radishes Also called oilseed radish, Daikon radishes (Raphanus sativus var. oleiferus) comes from two Japanese words: "dia" (meaning large) and "kon" (meaning root). Thought to have originated in the Mediterranian, Daikon radishes were brought to China around 500 B.C. and are still a staple in food dishes across Asia. Most Daikon radishes are white, but they can be yellow, green or black. Uses for Cover Cropping Daikon radishes are grown worldwide for cover cropping and food production. Cover cropping is using the natural properties of one or more plant species to help soil, reduce weeds and increase nutrient content for the benefit of the primary crop. Daikon radishes have been found to penetrate tough soils, absorb large amounts of nitrogen and provide a large above-ground foliage cover to suppress weeds. Daikon radishes germinate quickly, grow in cooler temperatures and are often planted in the fall. Left in the ground over winter to decompose, they then release the nitrogen back into the soil for next season's crop.
Culinary Uses Daikon radishes are the most widely grown vegetable in Japan. Daikon can be eaten raw, fried, grilled or boiled. When eaten raw, Daikon radishes are spicy. They become mild when processed. Daikon radishes are a good source of vitamin C, phosphorus and potassium. Daikon radishes are also low in calories (only about 18 calories per 100g) and are rich in enzymes to help aid in digestion. When to Harvest When used as a food crop, Daikon radishes can be harvested approximately 60 days after planting. If used for processing, roots should be allowed to grow to 12 to 14 inches. For fresh market sales, harvest roots at 2 1/2 inches. Tops break off easily during harvesting, so radishes should be harvested by hand. Use a digging fork to gently lift and loosen the soil around the radishes, then gently pull on the tops as close to the ground as possible. If you plant several crops in a row, you can harvest Daikon radishes for several weeks.

Bean plants are among the easiest vegetables to grow. They germinate quickly under the right conditions and produce flowers and fruit within 50 to 65 days, depending on the variety. If planted too early, though, beans may be slow to germinate or fail to germinate at all. Pay close attention to planting times and seed depth.
Time Frame Under good conditions, beans germinate in eight to 10 days. Beans may take two weeks or longer if the soil temperature is under 60 degrees Fahrenheit. Wait until daytime temperatures are above 75 degrees Fahrenheit before planting bean seeds for fast germination. Moisture Many people soak bean seeds before planting, but this procedure can actually hamper germination by causing the seeds to crack or rot. Beans germinate best in evenly moist, but not soggy soil. Heavy clay soils tend to stay wet longer in the spring. Amend them with organic matter such as compost or manure to improve drainage, or plant green beans in raised beds. Warmth In addition to improving drainage, raised beds warm up earlier in the spring, making them a good choice for gardeners in areas with short seasons. Another option is to lay black plastic over the soil two weeks before planting bean seeds. The plastic warms the soil and hastens seed germination. Remove the plastic before planting or cut slits in the plastic and leave it in place all summer. Plant green bean seeds 1 inch deep in sandy soils and 1/2 inch deep in clay soils that stay cold longer.
Considerations Planting beans in cups is a common preschool or kindergarten activity because the seeds germinate predictably, offering a first lesson in gardening. Beans don't handle transplanting well, though. Plant seeds directly in the garden after the soil has warmed for best results, rather than starting seeds indoors.

Choosing the right type of cauliflower (Brassica oleracea var. botrytis ) for your garden means you'll get the taste and color you want and that it will work for your climate. Although cauliflower is technically a perennial, you'll be it as an annual and it may need up to 108 days from transplant to harvest, although some varieties mature faster. Most cauliflower varieties will grow in U.S. Department of Agriculture plant hardiness zones 3 through 9. The cauliflower head is ready to harvest when its stunted flowers have formed into a dense, meaty "curd," which is white in classic cauliflower varieties, but can also be green, purple or orange.
Fast Growers Many cauliflower hybrids were produced to take advantage of short growing seasons and can be planted late in the season. These types mature as early as 50 days after planting. To protect the heads of white varieties and prevent them from turning green, it's important to tie the leaves around them, a process that's called blanching. Some varieties are self-blanching -- the leaves wrap around the heads by themselves. 'Snowball' Originating in France, 'Snowball' (Brassica oleracea var. botrytis 'Snowball') is a snow-white heirloom variety that was introduced to North America in 1888. It features a 6-inch head with tightly wound curds, and can be planted just before the last frost. It takes approximately 68 days to mature. This variety that requires slightly acidic soil with a pH between 6.5 and 7.0 and full sun. This is a self-blanching variety.
Related Hybrids 'Snow King' (Brassica oleracea var. botrytis 'Snow King') is a heat tolerant cultivar that matures quickly -- in as little as 50 days -- and produces a head that is 7 to 8 inches in diameter. 'Snow Crown' (Brassica oleracea var. botrytis 'Snow Crown') is another fast grower, reaching maturity 55 days after planting. The head grows to 7 or 8 inches in diameter. This variety is mildew resistant and keeps its flavor even if not harvested immediately. 'White Corona' (Brassica oleracea var. botrytis 'White Corona') has relatively small heads of only 3 to 4 inches, but it's one of the fastest growers of them all, maturing in only 30 days. Rainbow Colors Not all cauliflowers have white curds, and those that don't usually take longer to mature, and they don't need blanching. Because they take longer to mature, these varieties are often dense and have complex flavors.
'Alverda.pdf)' (Brassica oleracea var. botrytis 'Alverda') is similar to 'Romanesco' (Brassica oleracea var. botrytis 'Romanesco'), which is often misidentified as a type of broccoli but which, according to some, is not a cauliflower either. While 'Romanesco' is well-known for its geometric florets, 'Alverda' looks more like a traditional cauliflower. Sometimes called "broccoflower," it takes from 80 to 100 days to mature. Other greenish "broccoflowers" include: 'Green Goddess Hybrid' (Brassica oleracea var. botrytis 'Green Goddess Hybrid') 'Chartreuse Hybrid II' (Brassica oleracea var. botrytis 'Chartreuse Hybrid II') 'Vitaverde' (Brassica oleracea var. botrytis 'Vitaverde')
'Violet Queen' (Brassica oleracea var. botrytis 'Violet Queen') is a warm-weather variety that grows best in USDA zones 7 through 11. It takes from 65 to 70 days to mature, and the purple florets, which are high in beta-carotene, are flavorful enough to eat raw.
'Cheddar' (Brassica oleracea var. botrytis 'Cheddar') produces a curd that, like its namesake cheese, is orange in color, and mixing the melted cheese with the steamed vegetable is certainly recommended. Orange cauliflower was originally discovered in cauliflower patch in Canada, and has since been crossbred to produce the 'Cheddar' variety. It takes around 58 days to mature.

第一步：摘心 通过钎插或播种繁殖的小苗大多采用摘心的方法，可促使其多分枝和多花头、多开花，形成优美的株形，此法在室内观叶花卉的植株调整中应用比较普及；摘心也叫打尖或打顶，是将植株顶端细小的生长点部分去掉；破坏其枝条或植株的顶端优势，促使其下部两个或更多个隐芽（或潜在芽）萌发成新的枝条；为了收到较好的效果，有时可连续2－3次摘心，使一个顶尖能萌发出6－8个分枝，摘心通常用于草本或小灌木状的观赏植物；另外，可以通过摘心抑制植株的过快生长，促进枝条生长得充实，花和果实更大，观赏效果更好。
第二步：疏剪 对生长过于旺盛的植株，应适时地疏剪植株内的枝条或摘除过密的叶片，以改善其通风透光条件，使其生长得健壮，花和果实的颜色更艳丽；有些盆栽花卉往往花蕾形成过多；如茶花，为了花开得好，使花开得艳丽而味香，必须适当地剥蕾，每一小枝留1－2朵花就可以了，多余的花蕾全部用手掰掉；疏花尽量提前进行，以免消耗过多的养分，一般应在能够区分出花芽和叶芽以后便可以进行；否则，长势比较弱的植株，开成花蕾多，若任其全部开放，植株养分消耗过多，会严重影响其以后的生长；另栽在室内的观叶植物，还应经常将植株上的枯黄叶片、枝条及时摘除和剪掉，以保持清洁和减轻病虫危害。 第三步：抹头 许多观叶植物栽种数年后，植株过于高大；有些在室内栽培有一定困难，或下部叶片脱落、株形较差，失去观赏价值，这时候需要彻底更新，进行重新修剪或抹头，如大型乔木植物橡皮树、大灌木状的千年林、鹅掌柴、大型草本植物大王黛粉叶等，生长到一定程度时均需进行重修剪；通常的作法是在春季新梢萌发之前抹头，将植株上部全部前掉；留主干的高低视不同种类而定，抹头后的植株根部亦需相应调整，应清理掉腐朽的老根和旧土，用新培养土重新栽植，待其重新萌发、生长成新的植株，剪下的枝条可用作钎插繁殖用材料。
第四步：去异 在室内观赏植物中，有许多花叶品种是绿叶植株芽变形成的，在花叶品种的栽培中常常出现返祖现象而萌发出完全绿色的枝条；这些完全绿色的枝条就称为异枝条，异枝条不具本品种的特性；同时因全绿色枝条生长速度远远超过花叶枝条，如果不及时将绿色枝条剪掉，则花叶部分很快全部被绿化枝叶覆盖，失去原来花叶品种的特点；因此对花叶品种的观叶植物，如花叶薜荔、花叶扶桑的栽培中，应经常注意随时剪掉植株上萌生出的全绿色枝条，以保持花叶观叶植物的正常生长和具有良好的观赏价值。

每天24小时其中有1/3的时间都在办公室中度过，所以办公室的环境对于我们来说是非常重要的，下面就跟友友们分享一下办公室绿植摆放的一些技巧。
办公室植物摆放原则： 1、协调空间 要注意植物与空间的协调性，植物的色彩和姿态必须和空间取得协调，让人观感舒服，并且使植物与办公的人产生密切关联，创造温馨、充满生气勃勃的祥和高效的办公环境。 2、布置方便 办公空间的绿化应该讲求布置方便，常绿常青，而不必介意所种的植物品种是否为奇花异草，也不必在意能利用的空间有多大，办公室内的每个空间，都可以进行各种规模的绿化工程，绿化的关键是种些容易生长并且能令视觉愉悦的植物。 3、位置正确 普遍来说，办公空间的重点都在办公室的财位上，即办公大门的对角线位置，在此可以摆放个花盆，种植花期长、又具有吉祥意味的植物，在外观上植物应呈现直上形，以营造出素雅朴实、生机勃勃的办公风貌。 4、及时打理 办公室摆放着郁郁慧葱、生机盎然的花草盆栽，一方面可以愉悦视觉感官，更重贾的是，盆裁会在这个相对独立的空间里，形成一个充满生气的场，可以增加欣欣向荣的气氛。
植物推荐： 现在办公坏境多样，我们在追求宜人的办公坏境时候，更加注重绿色，环保，办公室装修过程中，我们要对整个设计理念中，假如绿色设计概念，对整个绿色布局要讲究下，我们可以在放置一些花草，这样可以起到调节净化空气的作用，也可以调节心理状态，缓解疲惫，放松心情。 1、吊兰、非洲菊、无花观赏桦：主要吸收甲醛，也能分解复印机、打印机排放出的苯，并能咽下尼古丁。 2、耳蕨、长春藤、铁树：能分解3种有害物质，即存在于地毯、绝缘材料、胶合板中的甲醛，隐匿于壁纸、印刷油墨溶剂中对肾脏有害的二甲苯，藏身于染色剂和洗涤剂中的甲苯。 3、红颧花：能吸收二甲苯、甲苯和存在于化纤、溶剂及油漆中的氨。 4、龙血树(巴西铁类)、雏菊、万年青：可清除来源于复印机、激光打印机和存在于洗涤剂和粘合剂中的三氯乙烯。 5、菊花：有吸收氟化氢的能力。 6、丁香、茉莉、米兰、玫瑰：有杀灭病菌的作用。 7、万年青、发财树、铁树和金钱榕：通过光合作用，吸收二氧化碳，放出氧气，使封闭式办公室内的空气变得清爽。

下面给大家详细讲解一下植物的幼苗期、营养生长期、生殖生长期及休眠期的施肥注意事项。
1、幼苗期：幼苗期由于苗较小，对营养的要求不高。如盆土中的基肥充足.基本上不用追肥。如盆土基肥较小，可少量的追施以氮肥为主的肥料，不宜太浓。因幼苗脆弱,浓肥易将幼苗烧死。 2、营养生长期：营养生长期是花卉大量长枝发叶的时期，此时对氣肥的要求较高。应追施以氮肥为主的肥料，浓度可较幼苗期施用的追肥浓。在此时期追肥时也不能忽视肥料中的磷钾肥的含量，如果只施氮肥，植株往往疯长,并且枝叶脆弱，节间过长，株形散，且易折断。
3、生殖生长期:生殖生长期是花卉孕蕾、开花、结果的时期，此时对诱神肥的需求量较大，应追施以磷钾肥为主的肥料（如磷酸二氢钾），如果此时氮肥充足，磷钾肥不足，往往易引起开花结果减少，并且易出现落花落果的现象。 4、休眠期：冬季休眠的花卉，在秋末休眠前应注意控制氮肥的施用量，以免诱发秋梢。秋梢会消耗花卉体内贮存的营养，影响第二年生长。并且发生秋梢的植株体眠推迟，寒冬来临后往往易遭受冻害。秋季适当的追施磷钾肥有利于花卉体内的营养积累，第二年生长更加旺盛。

书房，一个储藏知识的地方，一个家中办公的地方，如何让这样的地方待起来更加轻松呢？没错，植物。那么应该摆放什么植物呢？
发财树放在书房，体现宁静的氛围。 散尾葵能够有效去除空气中的苯、三氯乙烯、甲醛等有挥发性的有害物质。如学校书房没有空调，摆放散尾葵能够将室内的湿度保持在40%-60%，特别是冬季，室内湿度较低时，能有效提高室内湿度。 巴西木是颇为流行的室内大型盆栽花木，尤其在较宽阔的客书房内摆放，格调高雅、质朴。 金钱树是颇为流行的室内大型盆景植物，尤其在较宽阔的客厅、书房、起居室内摆放，格调高雅、质朴，并带有南国情调。
绿萝是比较常见植物，大盆绿萝放在书房显得大气，而且绿萝很好养，有净化空气的作用。 成都植物租摆书房植物摆放 春羽叶片巨大，呈粗大的羽状深裂，浓绿色，且富有光泽，叶柄长而粗壮，气生根极发达而被垂，株形优美，整个观赏效果好； 同时它又耐阴，是极好的室内喜阴观叶植物。它适于布置宾馆的大厅、室内花园、办公室及家庭的客厅、书房等处。 用虎尾兰来净化空气起到良好的作用。研究表明，虎尾兰可吸收室内部分有害气体，并能有效地清除二氧化硫、氯、乙醚、乙烯、一氧化碳、过氧化氮等有害物。

新装修的房子，除了一些异味以外，还会充斥的对人身体极有害的物质——甲醛，除了正常的通风外，我们还可以选一些植物来帮助我们进化空气，今天小编就给大家介绍几种适合装修完房子摆放的植物：
1、仙人掌：大部分植物都是在白天吸收二氧化碳释放氧气，在夜间则相反。仙人掌、虎皮兰、景天、芦荟和吊兰等却都是一直吸收二氧化碳释放氧气的。这些植物都非常容易成活。 2、吊兰：一盆吊兰在8至10平方米的房间就相当于一个空气净化器，即使是在没有装修的房间里，养一盆吊兰对人的健康也很有好处。 家里刚装修完，摆些什么植物好？ 如果想尽快驱除新居的刺鼻味道，可以用灯光照射植物。植物一经光的照射，生命力就特别旺盛，光合作用也就加强，释放出来的氧气比无光照射条件下多几倍。 3、平安树，目前，市面上比较流行的平安树和樟树等大型植物，它们自身能释放出一种清新的气体，让人精神愉悦。平安树也叫“肉桂”。在购买这种植物时一定要注意盆土，根和土结合紧凑的是盆栽的，反之则是地栽的。购买时要选择盆栽的，因为盆栽的植物已经本土化，容易成活。
4、芦荟：芦荟有一定的吸收异味作用，且还有美化居室的效果，作用时间较长。 5、绿色带果植物盆景：水果是最好的除味剂，如洋梨、橘子、香瓜、小南瓜等。将带果植物盆景放在新房内，既环保，香味又自然，还有益健康。
