秸秆直接还田氮素调节技术的研究

Study on the Technology of Regulating N after Returning the Stalks to Field Directly

本文通过对三年秸秆还田定位试验研究，提出了因还田的秸秆种类、数量、下季种植作物及秸秆还田年限而异的有利子节氮增产增收的调氮条件与方法。

According to the study of the fixed position test in returning the stalks to the field directly for three years, different conditions and methods of regulating N have been proposed, which are suitable to saving N and increasing grain yield, those are related to kind and amount of stalk、next cropping and the number of years for returning the stalks to the field continuously.
