西红柿叶片向上卷曲怎么办
   近日,菜农张师傅向育苗基质咨询:不知道是什么原因,近期棚内的西红柿总是出现卷叶的情况。记者来到棚内,看到西红柿中部叶片向上翻卷,并向上蔓延,?#29616;?#30340;植株叶片卷成筒状。番茄卷叶是因为根系供水不足导致叶片缺水,那么,?#36136;?#20160;么原因造成根系供水不足呢?育苗基质分析主要有以下两点。
    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.
  一是肥水不适伤根所致。当前春茬西红柿正处于结果盛期,为保证果实生长,很多菜农加大了浇水和施?#26623;俊?#33509;一次性浇水施?#26623;?#36807;大,很容易造成伤根,致使毛细根生长缓慢,根系受伤后,吸收水分的能力会随之下降,根系吸水量小,不能满足蒸腾作用的需求,因而造成了番茄卷叶。
    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。在采访中育苗基质http://www.fzdmn.tw/ 了解到,很多菜农存在相隔固定天数浇水的做法,但是,当前温度逐渐升高,西红柿叶片的蒸腾作用加强,若不及时进行浇水,高温干旱的条件下,番茄叶片的气孔就会关闭,也就出现了叶片从下部叶片开始向上翻卷?#21335;?#35937;。
    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,当前为防止西红柿发生卷叶,一定要注意合理的肥水管理,保持见湿见干的土壤条件。另外,番茄出现卷叶后,为促进叶片恢复,延缓其衰老,可叶面喷施细胞分裂素400倍混加核苷酸叶肥500倍,效果较好。
    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.
