控释氮肥在小麦上的示范应用效果
Application Effect of Controlled-Release Nitrogen Fertilizer on Wheat
摘要
Abstract
The application effect of controlled -release nitrogen fertilizer on wheat was researched by field demonstration test .The results showed that the use of controlled -release nitrogen fertilizer to reduce 30% of pure nitrogen increased the spike number per hectare , grain number per spike and 1 000-grain weight; the yield of the villages Qianzhuliucun and Zhongcun increased by 9.9%and 7.9%respectively .The use of con-trolled-release fertilizer to reduce 50%of pure nitrogen could increase 0.3 g of 1 000-grain weight but change fewer in grain number per spike , so the yield increased by 3.5%.The application effect of controlled -release nitrogen fertilizer reducing 30%pure nitrogen was obviously better than that reducing 50%nitrogen .关键词
