A few bok choy (Brassica rapa var. chinensis) flowers before the harvest don't have to mean total failure. The flower stalks indicate the first stages of the end of life for this cool-season vegetable, meaning no more leaves for the harvest. When the first yellow flowers appear, you have a few options to make the best of the situation. [图片]Harvest the Crop When one or two bok choy plants send up a flower stalk, the rest of the plants generally aren't far behind. At this point, harvest the rest of the bok choy plants by cutting each plant at the base, slightly above the soil line, with a knife. Cut carefully away from yourself to avoid injury. Disinfect the harvest knife in hot, soapy water or a solution of 1 part rubbing alcohol to 1 part water. Use bok choy fresh or store it in the refrigerator for two to three weeks. Pick the Flowers The bok choy's edible flowers taste best right before they open. If your bok choy crop is starting to produce elongated stalks and flowers from the center of each plant, pluck off the flower stalks and add them to salads. If the plant has only just begun to flower, you may still get a leaf crop. Pick a few leaves and taste them. If they're woody, pick the rest of the flowers and toss the plants on the compost pile. Otherwise, harvest the best tender leaves and flower stalks before discarding the plants. Collect the Seeds When bok choy flowers, you can harvest the seeds. Allow a group of plants to remain standing -- ideally two to three or more for pollination purposes -- until the flowers turn into seed pods. As the seeds mature, the pods turn from green to brown as they dry out. Cut off the pods and put them in a paper bag for a few weeks then break open the pods and dump the seeds into a separate paper bag. Store them in a dry spot until next planting season. Properly stored seeds can remain viable for up to five years. [图片]Prevent Flowering Bok choy bolts -- flowering and then going to seed -- rapidly in hot weather but you can slow the process by growing them from seed in late summer and early fall. In mild climates, plant bok choy in late fall and grow it through the winter. Bolting also occurs when optimal spring temperatures turn cold for a prolonged period and then suddenly warm again. Plants that are larger and more mature are affected the most by these changes in temperatures. You can even grow bok choy through the winter even in areas with mild frosts. Bolting is less likely to occur by planting transplants that haven't been stressed, keeping the garden weed-free and maintaining consistent water practices. Also, look for bolt-resistant varieties like "Joi-choi" and "Chin-Chiang." Before you plant, keep in mind that this plant can spread invasively in some areas.

金鱼藻常年生长在很少流动的水体深处。很多人喜爱把它养在室内，可见其观赏性居高。若是在适合它的环境下生长，恐怕连你的鱼缸都装不下它，没错，它的生长速度之快，是你无法想像的。快用它来装点一下你的室内哟。 [图片]一、金鱼藻简介金鱼藻，被子植物，别名细草、鱼草、软草、松藻，拉丁文名：CeratophyllumdemersumL.金鱼藻科、金鱼藻属悬浮于水中的多年水生草本植物，有根。叶轮生，边缘有散生的刺状细齿;茎平滑而细长，可达60厘米左右。金鱼藻多年生长于小湖泊静水处，于池塘、水沟等处常见，可做猪、鱼及家禽饲料。以全草入药，四季可采，晒干。主治血热吐血;咳血;热淋涩痛。沉水性多年生水草，全株深绿色。长20-40余厘米，疏生短枝。每5-9(13)枚集成一轮，无柄，长1.2-1.5(2.0)厘米，通常为1回二叉状分歧，有时为2回二叉状分歧，裂片丝状线形或线形，稍脆硬，先端具2个短刺尖。 [图片]二、金鱼藻怎么养首先，金鱼藻种植适合密集而不能稀疏。养殖者要想夺得高产，基本苗不足，那产量就难以上去。一般来说，养殖这种水草，应该按亩水域移栽200蓬为宜。其次，养殖过程中肥料应该肥而不能瘦。如果选择那些不能养鱼养虾的荒芜水面种植金鱼藻。这些较劣质的水域在种植前应该捞去水苔和其它杂草，然后按照每亩水面施过磷酸钙25千克作基肥，氮肥少施，以防绿藻占领水面。然后在栽种金鱼藻。第三，种植金鱼藻的水域不能过深，一般保持在1米范围之内最合适。因为，水过深纲粗叶就会少，使得产量大大降低，水草的利用率也降低，从而降低种植金鱼藻的商业价值。此外，正常情况下，从栽种金鱼藻到第一次采收一般为50天。采收的过程中需要注意，要将棍子拎起抖一抖，在水中转上4-5转，将棍子一横两手往上一拎。而第二次采收的时间应该是在30天后，第三次采收只要相隔几天即可。三、金鱼藻危害危害：金鱼藻分布全中国，特别是在水中富含有机质、水层较深、长期浸水的稻田中分布较多，危害较重。此外，静水池塘、湖泊、沟渠中亦有分布。由于金鱼藻吸氮能力极强，同时降低水温，严重影响水稻分蘖及生长发育。治理：防除应采取农艺措施和化学除草相结合的方法。 (1)农艺措施主要有：一是建立地平沟畅、保水性好、灌溉自如的水稻生产环境;二是结合种子处理清除杂草的种子，并结合耕翻、整地，消灭土表的杂草种子;三是实行定期的水旱轮作，减少杂草的发生;四是提高播种的质量，一播全苗，以苗压草。 (2)化学除草，多数地方采用一次性封杀，就是在播种(催芽)后1-3天内，亩用40%“直播青”可湿性粉剂60克，兑水40-50公斤，均匀喷雾，施药时田板保持湿润。3天后恢复正常灌水和田间管理。通过化除后，如果后期仍有一定量的杂草，可采取针对法进行补除。以上就是小编为大家介绍的金鱼藻的相关内容，希望能够帮助到您。

绿萝又名黄金葛、抽叶藤，为天南星科绿萝属多年生常绿藤本植物。原产于亚洲马来半岛和南美巴西一带的热带雨林。绿萝作为一种耐阴观叶植物，十分适合于室内栽培、观赏，是一种不可多得的室内盆栽观叶植物。其缠绕性强，气根发达，可以水培种植。那么，绿萝长高了怎么办呢?该如何处理? [图片]一、绿萝长高了怎么办绿萝长高了怎么办,有一些花友家里的绿萝很给力，结果长的太高了，这里需要和花友普及一些关于绿萝的基础知识，绿萝是常绿藤本植物，生长于热带地区常攀援生长在雨林的岩石和树干上，可长成巨大的藤本植物。绿色的缠绕性强，气根发达，既可让其攀附于用棕扎成的圆柱上。知道绿萝是怎么一回事就要说说绿萝长高了要怎么办了，其实这个问题没有一个标准的固定答案，只能说花友根据个人的喜好来选择，这里我们说几种常见的处理方法。 1、让生长点向下继续生长的方法，让其再向下生长。 2、将上部的嫩枝剪下扦插，作为垂吊欣赏。 3、离盆土15-20厘米处全部剪断，让其重新生长新的枝叶，此为更新法，但周期较长。另外要说明的就是由于绿萝生长块，所以盆栽的绿萝不可能永远保持刚买来的形态，而且绿萝不易发侧枝，修剪并不能解决长高的问题，另外随着时间变化绿萝底部会逐渐枯黄，影响美观，所以花友可以养成扦插繁殖绿萝的习惯，这样可以达到不断补充新绿萝的目的。 [图片]二、绿萝日常管理水培绿萝一般放在室内的朝阳地方生长可以保持温暖的温度和比较好的光照促进植物生长，另外它不可以直接接受太阳的照射，冬季尤其是在我国北方种植的冬季非常寒冷这时候要适当地采取保温措施。在水培绿萝生长不同阶段要根据生长需要进行追加施肥保证营养供给。水培绿萝对水分要求比较大，要使的土壤保持湿润，一个月浇一次大水，然后每天可以擦拭叶子保证鲜活。定期对水培绿萝进行修剪保持枝叶的有型和翠绿，并要对病虫害进行预防和治疗。以上就是小编为大家介绍的绿萝长高了怎么办，希望能够帮助到您。

Watermelon on the Fourth of July is about as American as apple pie, but the fruit actually originated in Africa, the University of Arkansas Extension reports. Today, the melons -- a warm-season crop -- grow commercially and in backyard gardens in many parts of the United States. The warm summers in zone 6 -- which includes much of Kentucky and Tennessee as well as portions of Kansas, Arkansas, Missouri, Illinois, Indiana, Ohio, Pennsylvania and West Virginia -- are suitable for growing watermelons. [图片]Step 1 Create soil hills in your garden space by piling soil in mounds. If you intend to plant several watermelons, set the hills 6 feet apart, the University of Arkansas Extension advises. Plant rows of watermelons 7 feet to 10 feet apart. Step 2 Plant several watermelon seeds 1/2 inch deep in the hills, covering them carefully with soil. Watermelons should be planted when the threat of frost has passed and the soil has warmed. In zone 6, this generally occurs in the middle of May. Step 3 Water the plants carefully at planting time so that they can begin to establish their roots. Continue watering as necessary during the growing season so the soil does not dry out. In general, watering is only required during extended dry periods because the plants have a deep root system that can meet their moisture needs. [图片]Step 4 Remove the smallest young plants after they sprout through the soil, leaving only two to three seedlings in each hill. It's always best to keep the largest, most healthy-looking plants and thin out the small or weak plants. Step 5 Weed the garden space regularly, either by hand or with a hoe. Weeding is especially important early in the season, when the plants are setting their roots. Step 6 Monitor the plants for signs the melons are ripe starting about 80 days after you planted them. Gardeners often have difficulty determining when to harvest watermelons, but there are several signs to watch for. First, a ripe watermelon will have a dull green color. The tendrils will turn from green to brown and the spot where the melon sits on the ground will turn from green to yellow.

All plants have roots through which they derive nutrients from the soil. When these roots are edible, they are called "root vegetables." When preparing carrots, for example, it is usual to cut off and discard their leaves, known as greens, and eat the long, orange roots. Consumption of root vegetables is common around the world. Some vegetables of similar appearance, especially nonroot tubers, are occasionally incorrectly considered root vegetables. Taproots [图片]Taproots are long, sometimes slender roots that plunge deep into the soil. Carrots are the most familiar taproots in everyday use. Carrots are related to parsley, which are prized for the green leaves. Carrots originated in Afghanistan but are now grown and eaten around the world. Other taproots include parsnips, turnips, rutabagas, daikons, celeriac, radishes and beets. Although some taproots, such as parsnips, are most often served cooked, many can be eaten raw or incorporated raw in salads and other dishes. Tuber Roots [图片]Tubers, in comparison to taproots, tend to be larger and more squat in shape. Tuber roots can store large quantities of nutrients, which helps some plants make it through long winters. Sweet potatoes and yams are familiar examples of tuber roots. They are often confused because they have a similar appearance and flavor. Traditionally sweet potatoes grown and eaten in the southern U.S. are called yams even though, strictly speaking, they are sweet potatoes. Often large and high in sugar, sweet potatoes and yams are best cooked before eating. Other examples of tuber root vegetables include cassava, yucca and manioc. Potatoes [图片]Although potatoes are tubers, not root vegetables, they are often grouped with yams and sweet potatoes, which are tuber roots and true root vegetables. The potato is technically a stem rather than a root. Indeed, anyone who has kept potatoes too long will have seen them sprout roots. The potato does perform a similar function to a tuber root, storing nutrients from the soil. Potatoes are one of the world's main dietary staples. Other Similar Vegetables [图片]In addition to the potato, other tubers and some bulbs are sometimes classed with root vegetables, although in strict botanical terms they are not roots. Among these are tigernuts, groundnuts, sunchokes, arrowroot and lotus root. Members of the onion family -- including onions, shallots, garlic -- are bulbs rather than roots.

If you want an abundant crop of orange pumpkins for use at Halloween or for making pies for Thanksgiving, Ohioans must prepare a garden plot and plant after danger of frost passes in spring. Depending on pumpkin cultivar, a warm growing period of 100 to 120 days allows the pumpkin vine to flower and develop harvestable fruits. If possible, time the spring planting so that the pumpkins ripen on the vine in early October. [图片]Planting Time Pumpkins do not tolerate frost. Across the vast majority of Ohio, the last frost in spring occurs anytime from April 21 to May 10, depending on latitude and elevation. Contact your local cooperative extension office to learn of the last spring frost date in your county, or speak to staff at your local garden center. Wait an additional two to four weeks after your area's last frost date to allow the garden soil to sufficiently warm to at least 65 degrees Fahrenheit. An appropriate pumpkin planting time frame is from mid-May to early June in most parts of Ohio. Timing Considerations Because pumpkins take 100 to 120 days from germination to harvest, you don't want to plant pumpkin seeds or transplants too early in spring. Although you must avoid frost, cool soil temperatures inhibit growth and may lead to root rot. Pumpkins tend to soften and rot on the vine if they ripen too early, such as in late August or September. Aim for pumpkins to pick around October 1. Look at the pumpkin seed packet for the "days to harvest" data. Count backward that number of days from the target October harvest date. This provides you the ideal sowing date in your Ohio locale. Planting Pumpkin Seeds Sow pumpkin seeds in hills. A hill is a shallow planting basin about 1 inch deep and 6 to 10 inches wide. Place four or five pumpkin seeds in the hill and cover with 1 inch of soil. Additional hills need to be spaced 6 to 10 feet apart. Hills oriented in long rows need about 15 feet between rows. This allows room for the sprawling vines to grow and still receive ample sunlight. [图片]Growing Giant Pumpkins Everyone admires a gigantic pumpkin to use as a jack-o' lantern around Halloween. The pumpkin varieties that produce the largest fruits need at least 120 days to germinate, grow and produce ripe pumpkins. According to David A. Mangione of the Ohio State University Extension, it's behooving to start seeds of these long-maturation pumpkins indoors about two weeks before planting them outdoors. He suggests sowing seeds indoors in late April and transplanted them outdoors in May or June when soil is warm and frosts no longer occur.

Growing lettuce (Lactuca sativa) in your garden means you can have the freshest leaves for perfectly crisp salads. To enjoy the best-tasting fruits of your labors, it all comes down to picking the lettuce leaves at the right time and storing the lettuce correctly after you've harvested it. [图片]Check Your Calendar How long it is since you sowed the seeds provides a quick way to estimate when lettuce should be ready for harvesting. A crisphead lettuce variety, which grows into a hard, tight head of leaves, is ready for harvesting approximately 75 days after planting. As their name implies, loose-leaf lettuces don't form a head and are ready in as little as 45 days. Butterhead varieties, which soft heads of loose leaves, are ready in 55 to 75 days. Romaine varieties grow into tall, cylindrical heads of folded leaves and take approximately 70 days to mature. Pick It Early Pick lettuce in the early morning before the heat of the day causes the lettuce leaves to lose their crispness. Lettuce is fresher and crisper at this time and also tastes sweeter. Test for Readiness For loose-leaf lettuce varieties, the outer leaves can be harvested on a continuous basis when the plant reaches its harvest-ready date. As you pick the outer leaves, the plant continues to grow from the middle. These leaves should be full sized and tender. Woody leaves were left on the plant too long and will taste bitter. Butterhead lettuce and other head varieties are ready for harvesting when the inner leaves have formed a head and the plants approach their variety-specific maturity date. To test if the head is ready, gently push down with the back of your hand. It should feel firm and crisp. [图片]Harvest Methods Harvest methods differ depending on the type of lettuce you're picking. For loose-leaf varieties, use your fingers to pinch off individual lettuce leaves at the base of the plant. For lettuce heads, use a sharp knife or pruning shears and cut off the entire head at its base, approximately 1 inch above soil level. Use cutting tools that have been wiped with a cloth soaked in rubbing alcohol. This helps prevent the spread of disease. Cleaning and Storing Lettuce Refrigerate lettuce leaves immediately after picking, as unrefrigerated leaves can wilt within 15 minutes of harvesting. Place the lettuce in a loose plastic bag, unwashed. Washed lettuce deteriorates quickly, but dry, unwashed lettuce can last for up to 14 days in your fridge's crisper drawer. When you're ready to use the lettuce, rinse each leaf under cold running water to get rid of dirt and any other debris.
