在有机肥料与化肥配合施用时,怎样确定各自的施用适期,使两类肥料都能充分发挥作用而达到增产增收的目的,是个值得讨论的问题。一、从水稻施肥的历史经验看小麦的施肥制度在生物学特性及栽培条件方面,水稻和小麦虽有很大差别,但是在施肥方面,也有可以相互借鉴的地方。如日本在施用化肥的早期阶段,也曾由 In the organic fertilizer and fertilizer with the application, how to determine the appropriate application period, so that both types of fertilizers can fully play the role of production and income to achieve the purpose, it is a question worth discussing. First, from the historical experience of fertilization of rice to see the fertilization system of wheat In terms of biological characteristics and cultivation conditions, rice and wheat, although very different, but in fertilization, there are also places to learn from each other. Such as Japan in the early stages of the application of fertilizers, have also been
