小麦往往由于肥水过多,使田间植株郁闭,节间延长,茎秆弱,中上部叶片大而长,头重脚轻,遇风造成倒伏。一般认为第一节间超过10厘米,第二节间超过15厘米,中上部叶片超过18厘米,多发生倒伏现象。防倒伏的办法,一是培育矮秆品种,二是控制肥水,采用“蹲苗”的办法,前者至今还未得到理想的品种,后者往往受自然条件限
Wheat is often due to too much water and fertilizer, so that field plants closed, internode extension, stalk weak, middle and upper leaves large and long, top-heavy, encountering wind caused lodging. It is generally believed that the first internode exceeds 10 cm, the second internodes exceed 15 cm, the middle and upper leaves exceed 18 cm, and the phenomenon of lodging is more likely to occur. Anti-lodging approach, first, to cultivate dwarf varieties, the second is to control the fertilizer, the use of “Dunmiao” approach, the former has not yet been the ideal species, the latter often subject to natural conditions
