小麦的叶部施肥已在生产上得到了较为广泛的应用,效果较为明显。一、小麦叶部施肥的作用(一)增加产量小麦叶部施肥,无论氮肥、磷肥、钾肥,还是硼、锰、铜、锌、钼等微肥,无论是植物激素,还是某些肥料和激素及农药混用,都能促进增产。小麦体内需氮时,氮素通过叶部施用,对促进其体内叶绿素和蛋白质的形成,比土壤施入的既快又多。据观察,在小麦叶部喷施氮肥后一两天就能加 Leaf foliage fertilization in wheat has been more widely used in production, the effect is more obvious. First, the role of wheat leaf fertilization (A) increase the yield Wheat leaf fertilization, regardless of nitrogen, phosphate, potassium, or boron, manganese, copper, zinc, molybdenum and other micro-fertilizers, whether plant hormones, or some fertilizers and hormones And pesticide mix, can promote the increase. When nitrogen is required in the body of wheat, nitrogen is applied through the leaves to promote the formation of chlorophyll and protein in the body, much faster and faster than the application of soil. It is observed that in the wheat leaves after spraying nitrogen can be added a day or two
