肥料的合理运筹是小麦栽培的关键技术措施之一。近年来市郊农场在小麦生产上普遍采用了“二促施肥法”,这对小麦单产的提高起到了明显的作用。为了进一步摸清氮肥施用的最佳时期,为小麦合理施肥提供科学依据,从1984年起,我站协同跃进、五四等农场科研站进行了小麦不同叶龄期施用氮肥的研究,现将研究结果简述如下。
Fertilizer rational operation is one of the key technical measures of wheat cultivation. In recent years, suburban farms in the wheat production generally adopted the “two fertilizers”, which increased wheat yield has played a significant role. In order to further clarify the best period of nitrogen fertilizer application, to provide a scientific basis for rational wheat fertilization, since 1984, I stand synergistic leap forward, May Fourth Farm Research Station wheat nitrogen application at different leaf ages, now study The result is summarized as follows.
