以玉米生长的必需元素为例,通过木桶原理说明限制作物产量的决定性因素。并通过介绍近年来化肥施用的变化历程,分析不合理施肥对土壤造成的影响,提出了合理施用中微量元素和微生物菌肥是打破目前农作物增产极限的有效措施。
Take the necessary elements for the growth of corn as an example to illustrate the decisive factors that limit crop yields through the principle of barrels. By introducing the changing course of chemical fertilizer application in recent years and analyzing the influence of irrational fertilization on soil, it is put forward that the reasonable application of trace elements and microbial fertilizer is an effective measure to break the limit of increasing crop yield.
