众所周知,肥料是小麦增产的物质基础,而小麦追施化肥能显著地增加产量。为了达到科学地、经济地使用化肥,用最少的肥量来获得最大的经济收益,我们对春麦施用化肥的几个技术问题,进行了比较试验,现将结果摘要如下: 一、化肥深施效果好 通过几年的探索与实践,小麦追施化肥,深施较撒施增产17.8％,在追肥量相同的情况下,深施肥每公斤化肥(尿素)比撒施肥多增产3.4斤小麦籽粒。
It is well-known that fertilizers are the material basis for increasing wheat yield while wheat topdressing fertilizers can significantly increase yields. In order to achieve scientific and economical use of chemical fertilizers, with the least amount of fertilizer to get the maximum economic benefits, we applied several technical problems of spring wheat, and compared the results are summarized as follows: First, the effect of fertilizer deep application Good through several years of exploration and practice, topdressing chemical fertilizers of wheat, applying more facilities than the yield of 17.8%, in the case of the same amount of fertilizer, the deep fertilization of fertilizer (kg of urea) than the yield of more than 3.4 kg of wheat grain yield.
