西紅柿葉片向上卷曲怎么辦
   近日,菜農張師傅向育苗基質咨詢:不知道是什么原因,近期棚內的西紅柿總是出現卷葉的情況。記者來到棚內,看到西紅柿中部葉片向上翻卷,并向上蔓延,嚴重的植株葉片卷成筒狀。番茄卷葉是因為根系供水不足導致葉片缺水,那么,又是什么原因造成根系供水不足呢?育苗基質分析主要有以下兩點。
    Recently, the master Zhang to matrix consulting seedling: don't know what the reason is, the recent greenhouse tomatoes is always rolled leaf situation. Reporters came to the studio, see the tomatoes middle leaves rolled up, and spread upward, rolled into a tube shaped leaves serious. Tomato leaf curl is because of insufficient water supply shortage caused the blade root, then, and what are the causes of root water shortage? Seedling matrix analysis are mainly in the following points.
  一是肥水不適傷根所致。當前春茬西紅柿正處于結果盛期,為保證果實生長,很多菜農加大了澆水和施肥量。若一次性澆水施肥量過大,很容易造成傷根,致使毛細根生長緩慢,根系受傷后,吸收水分的能力會隨之下降,根系吸水量小,不能滿足蒸騰作用的需求,因而造成了番茄卷葉。
    One is the discomfort caused by root fertilizer. The current spring tomato is the results of peak, in order to ensure the fruit growth, many farmers to increase the watering and fertilizing amount. If the one-time watering and fertilizing amount is too large, it is easy to cause root damage, resulting in Mao Xigen slow growth, root injury, the ability of water absorption decreases, water uptake by roots is small, can not meet the transpiration demand, resulting in tomato leaf curl.
  二是土壤缺水干旱所致。在采訪中育苗基質http://www.1096095.com/ 了解到,很多菜農存在相隔固定天數澆水的做法,但是,當前溫度逐漸升高,西紅柿葉片的蒸騰作用加強,若不及時進行澆水,高溫干旱的條件下,番茄葉片的氣孔就會關閉,也就出現了葉片從下部葉片開始向上翻卷的現象。
    The two is caused by soil drought. In an interview with the substrate to know, many farmers are separated by a fixed day watering practices, however, the temperature increases gradually, strengthen the transpiration of tomato leaf, if not timely watering, high temperature and drought conditions, stomatal will tomato leaves off, also appeared in the leaves from the beginning of the lower leaves rolled up the phenomenon of.
  因此,當前為防止西紅柿發生卷葉,一定要注意合理的肥水管理,保持見濕見干的土壤條件。另外,番茄出現卷葉后,為促進葉片恢復,延緩其衰老,可葉面噴施細胞分裂素400倍混加核苷酸葉肥500倍,效果較好。
    Therefore, in order to prevent the occurrence of the tomato leaf curl, attention must be paid to the management of water and reasonable, maintain see see wet soil conditions. In addition, the tomato has rolled leaf, in order to promote the recovery of the leaves, delay the aging, can be sprayed 400 times mixed with cytokinin nucleotides leaf fertilizer 500 times, good results.
