采用田间示范试验研究了控释氮肥在小麦上的应用效果。结果表明：使用控释肥，降低纯氮30％，小麦的公顷穗数、穗粒数、千粒重均有所增加，前诸留村的增产率为9．9％，中村的增产率为7．9％；降低纯氮50％，小麦的穗粒数基本不变，而千粒重增加0．3 g，增产率为3．5％；控释氮肥施用量降氮30％的示范应用效果明显优于降氮50％的。

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 .
