梅雨时期很多植物都都会或多或少遭受一些病虫害的侵入,而此时也需要我们格外的用心去照顾它们。而杜鹃的花期在5-8月,由于不同的品种可能花期也会存在一定延迟。而作为夏季6-7月份的梅雨季节,恰逢杜鹃盆景花枝招展、竞相开放的季节,虽然在这个时间段更加适合赏花,同时也需要及时做好养护管理工作。否则,如果呵护不到位的话,可能引起花叶焦枯脱落的现象,这对于盆景而言是莫大的损失,对于赏花者而言,也必然让人感到遗憾,毕竟盆景的观赏价值会大打折扣。
从夏季的6月到七月上旬期间恰逢是梅雨季,同时也正是杜鹃开花抽叶、发枝旺盛的时期,所以需要尽可能为其提供光照。只要不是被长时间暴晒,一般不会对开花造成什么影响。但如果在烈日当空的晴天,一般从上午9点到下午4点之间这段时间需要及时采取必要的遮阴措施,以避免烈日灼伤花叶而出现杜鹃出现花叶焦枯脱落的现象。但仅此还不够,以为杜鹃耐寒而不耐热,当气温高于30°C时,往往脱水比较严重,同时也容易出现休眠现象,所以为了确保其在梅雨季开花旺盛,遮阴、降温、保湿等工作一定要做好。
杜鹃盆景在梅雨季出现花叶焦枯脱落的现象,主要是光照过强、气温太高、脱水严重等因素造成的。所以,为了避免这种现象的发生,我们首先需要将杜鹃盆景摆放在相对凉爽、通风顺畅的环境中养护,同时做好遮阴工作,一般为其提供半阴的环境即可。当然,确保杜鹃盆景在梅雨季不会出现花叶焦枯脱落的现象,仅仅靠遮阴通风的条件还不够,我们还需要及时做好补水工作。
杜鹃本身是比较喜欢湿润但不耐高温的生长环境,所以当发现盆土变干时要及时浇水,多在早上9点之前或下午4点之后进行。而为了达到降温保湿的效果,我们还需要结合喷水进行,尤其是在像梅雨季的6-7月这种炎热的夏季环境下,更应该多喷洒叶面水和地面水。喷洒叶面水和地面水除了可以起到保湿降温的作用之外,也可以让杜鹃盆景的叶片更显干净、鲜绿,而实现鲜花配绿叶的效果,提高盆景的观赏价值。不过浇水不宜太多,否则仍然可能引起落花的。
当然一般情况下,处于花期的花卉植物是不宜进行追肥的,尤其是处于梅雨季且不耐高温的杜鹃盆景,更应该在花期停止追肥。除此之外,也需要做好病虫害的管理,因为在湿热通风差的环境下,杜鹃盆景比较容易感染病虫害。相信只要通过大家对杜鹃盆景进行精心的呵护和管理,梅雨季出现花叶焦枯脱落的现象会逐渐消失的,而盆景的观赏效果也能得到保障。

虫害分布
主要分布于中国浙江、福建等地。
虫害形态特征
成虫
雌虫体长7-9 mm。体黑色,有天蓝色光泽。触角黑色,9节,密生黑色绒毛。前翅淡烟褐色;翅柄黑色,中央稍带黄色;翅脉黑色。前足及中足腿节尖端、胜节、第一、二跗节或第一、三胫节,后足腿节尖端、脱节均黄白色。唇基前线平直,中窝深,近圆形。触角沟深。横缝及侧缝深,冠缝隐晦。头部及胸部刻点细稀;中胸前侧片几乎无刻点。头、胸部细毛黑色。雄虫体长5-7mm。中胸后片后端刻点较密。触角9节,第三节长度与第四、第五节长度和之比为1:1:1。其余色泽及构造(外生殖器除外)同雌虫。
卵
长椭圆形,长约2 mm,宽0.8 mm。初产时为粉红色,近孵化时变为灰色。
幼虫
初孵幼虫身体淡黄色,头黑色。5龄幼虫后期,腹部气门下线处每节各有2个黑点,6龄时黑点成肉瘤状。老熟幼虫身体黄色发亮,气门黑褐色,腹部有2排横向排列的刺。
蛹
长约10 mm,刚化蛹时,身体淡黄色,足白色透明。近羽化时为揭黑色。
虫害发生规律
竹林区 1年发生1代或2代,以老熟幼虫在上中1-4 cm深处结茧变为预蛹越冬。翌年5月中旬开始化蛹,5月下旬始见成虫,6月上旬为羽化盛期,6月下旬为羽化末期;6月上旬开始产卵,中旬为产卵盛期;6月中旬卵孵化,7月中旬幼虫进入7龄,并陆续下竹入土。其中部分发生2代的老熟幼虫8月下旬开始化蛹,9月上旬开始羽化,中旬为羽化盛期,并开始产卵,9月下旬卵孵化,10月下旬幼虫老熟下竹。幼虫从竹杆上爬行下竹,至地面入土作茧静伏其中。同一批蛹雄成虫比雌成虫羽化早。
在羽化始盛期,雄成由约占78%,至盛期雌成虫的占70%。雨天基本不羽化;天气晴朗,有利于成虫羽化。雌雄性比一般为1:2.2。成虫羽化后喜成群活跃在阳光充足的东南坡毛竹、杂竹及其它植物顶部,阴天停息于叶片上,很少活动。交尾前,雌、雄成虫均在竹冠顶部成群飞舞。交尾后,卵产于毛竹或杂竹的叶肉组织内。产卵时,成虫停息在竹叶上,腹部紧贴叶片,从主脉两侧的叶片正面将卵产入。每产1粒卵移动约1mm,卵成“一”字形排列。一般每叶产卵1排偶有2排。产卵部位的叶背稍有泡状隆起。卵快孵化时,卵边缘出现小黑点。同一卵块的卵多在同一时间孵化。孵化率:第一代为50-100%,平均93%;第二代为20一100%,平均 75.4%。孵化时,幼虫多从正面咬一小孔钻出,少数从叶背钻出,不食卵壳。
幼虫孵出后即在原产卵叶上取食,全部幼虫沿叶缘排成一队,头向叶基,前一条幼虫的尾部翘在后一条幼虫的头上,从叶尖吃向叶的基部,常将叶食尽,仅留主脉,以后一起转移至另一叶片上取食。 4龄幼虫开始分散取食。幼虫蜕皮6次。蜕皮前停止取食,排尽体内粪便。蜕皮时用尾钩住被食叶的主脉或其他部位,由体中前部胀直,头亮与前胸间的旧蜕不断膨胀,伸胀几次后头壳开裂,虫体逐渐伸出。从脱裂线胀开到虫体爬出约需15分钟。脱皮后约75分钟,头壳成黑色,随即幼虫开始爬行活动。幼虫每次脱皮后,体长和头壳明显增大;而7龄幼虫体长自脱皮3-6天后缩短,此时开始爬行下竹,寻找适宜地面入土作茧。
虫害防治方法
1.加强毛竹林抚育,铲除林内或林缘蜜源植物,以断绝毛竹黑叶蜂补充营养来源。
2. 人工防治:(1)幼龄幼虫群集叶上时,可采取人工捕捉方法。(2)利用幼虫假死性,3龄后于树下铺张塑料薄膜,震动树干,收集落下幼虫拿来沤肥。
3. 生物防治可喷1亿孢子/毫升苏云金杆菌、10亿孢子/毫升白僵菌防治2—3龄幼虫。
4. 化学防治:(1)对幼龄幼虫可 用45%丙溴辛硫磷(国光依它)1000倍液,或国光乙刻(20%氰戊菊酯)1500倍液+乐克(5.7%甲维盐)2000倍混合液,40%啶虫.毒(必治)1500-2000倍液喷杀幼虫,可连用1-2次,间隔7-10天。可轮换用药,以延缓抗性的产生。(2)对于成虫可利用其取食花蜜习性,喷45%丙溴辛硫磷(国光依它)1000倍液。

Sometimes called purple queen, purple heart (Setcreasea pallida) is a low-growing tender perennial grown for its showy violet leaves and sprawling, dark-purple stems. It grows in U.S. Department of Agriculture plant hardiness zones 7 through 11 and it's usually used as a ground cover or container plant. Purple heart needs little care, but providing some general maintenance will keep it looking its best.
Seasonal Watering
Although highly drought-tolerant once established, purple heart will look tidier and more lush if it gets regular water in summer. Water it weekly from spring until fall, providing 1 inch of water each time. Allow the soil to dry out on the surface between waterings to keep the roots healthy. During times of extreme heat or drought, increase watering to twice weekly if the soil is drying out faster than normal. Reduce watering to once every two weeks in winter and provide no water during rainy weather. Pot-grown purple hearts should also be watered whenever the soil dries on the surface. Water until the excess flows from the drainage holes of the pot. Always use pots with drainage holes for this plant.
Fertilizer Needs
Purple heart uses its soil nutrients efficiently and requires little supplemental fertilizer. Potted plants or those grown in poor or especially fast-draining soil may need a boost of nutrients during the active growing season to enhance their lush, violet foliage. Dissolve 1/2 teaspoon of general-purpose, 15-15-15 ratio fertilizer in 1 gallon of water. Apply the solution monthly and watch for pale or washed out-looking foliage, which is a sign of overfeeding. Reduce feeding to once every two months if the purple heart's foliage turns pale or if it starts producing an abundance of leggy, weedy growth.
Pruning and Grooming
Among purple heart's most positive attributes is its gracefully trailing habit and vigorous growth. This is also one of its greatest drawbacks because can quickly overtake a bed or produce spindly, unattractive growth if left unpruned. Pruning purple heart should be done in spring or early summer just after it finishes flowering. Remove up to two-thirds of the growth to promote a fuller, bushier appearance and encourage more blooming. Before pruning, soak your shears in a solution of equal parts water and rubbing alcohol or full-strength household disinfectant for five minutes and then rinse the blades. The pruned stems can be discarded in a green waste can or used to propagate new purple heart plants.
Considerations
Purple heart doesn't have serious pest or disease issues if it is grown under the right conditions, making it a smart choice for a low-maintenance yard. But it does have some significant drawbacks that may cause issues in your garden. Its vigorous growth may become invasive in warm, frost-free climates. Keeping it pruned helps limit its spread, but it may also require inorganic mulch or an underground root barrier to keep its roots from spreading. Another issue with purple heart is its foliage, which may irritate the skin. Growing it in a pot will address both concerns, as long as the pot is kept away from where people might accidentally brush against it.
