以冬小麦为试验材料,研究腐植酸尿素对其产量构成因素、产量及氮肥利用率的影响。试验结果表明:腐植酸尿素能显著提高冬小麦产量、千粒重及氮肥利用率。施用腐植酸尿素I型和腐植酸尿素II型与农民习惯施肥相比,冬小麦产量分别增加753.2、756.9 kg/hm~2,千粒重分别提高1.3、1.4 g,氮肥利用率分别提高11.97、11.60个百分点;与普通BB肥相比,冬小麦产量分别增加897.7、894.0 kg/hm~2,千粒重分别提高0.5、0.6 g,氮肥利用率分别提高10.11、9.74个百分点。
Winter wheat was used as experimental material to study the effects of humic acid urea on yield components, yield and nitrogen use efficiency. The results showed that humic acid urea significantly increased winter wheat yield, grain weight and nitrogen use efficiency. The humus urea type I and humic acid urea type II increased the yield of winter wheat by 753.2,756.9 kg / hm ~ 2 and the grain weight increased by 1.3,1.4 g and the nitrogen use efficiency increased by 11.97 and 11.60 percentage points Compared with the normal BB fertilizer, the yield of winter wheat increased by 897.7 and 894.0 kg / hm ~ 2, the grain weight increased by 0.5 and 0.6 g respectively, and the nitrogen use efficiency increased by 10.11 and 9.74 percentage points respectively.
