叶面喷肥,就是直接把肥料喷在叶片上,使肥料从叶的角质层和气孔进入,通过质膜进入细胞,被小麦吸收。尤其是在小麦生长的中后期,植株较高,叶片封行,不便采用地面施肥的办法,采用叶面喷肥,既防止对小麦的损伤,又解决了小麦在生产过程中对肥料的需要。这样可延长叶片寿命,增强光合作用,使籽粒饱满,千粒重增加,同时也减轻千热风的危害,达到增产的目的。试验证明,中后期进行小麦叶面喷肥,一般 Foliar spray, that is, the fertilizer sprayed directly on the leaves, the fertilizer from the stratum corneum and stomata into the membrane, through the plasma membrane into the cell, was absorbed by wheat. Especially in the middle and late wheat growth, the plants are higher, leaves sealed, inconvenience to use the ground fertilization approach, the use of foliar spray, both to prevent damage to wheat, but also to solve the wheat in the production process of fertilizer needs. This will extend the life of the leaves and enhance photosynthesis, so that full grain, 1000-grain weight increase, but also reduce the harm of thousands of hot air to achieve the purpose of increasing production. Test proved that in the late wheat foliar fertilizer, in general
