缓释氮肥不同施氮量对春小麦生长及产量的影响
Effects of Different Nitrogen Application Rates of Slow-Release Nitrogen Fertilizer on Growth and Yield of Spring Wheat
摘要
Abstract
To explore the effects of different nitrogen fertilizer application rates of slow-release nitrogen on the yield of spring wheat,five treatments were set up:no fertilizer application,application of urea for nitrogen application rate of 240.0 kg·hm-2,and slow-release nitrogen application rates of 240.0 kg·hm-2,192.0 kg·hm-2,and 168.0 kg·hm-2.By studying the effects of different slow-release nitrogen fertilizer application rates on the growth,development,yield and economic benefits of wheat,the optimal application rate of slow-release nitrogen fertilizer was determined.The results showed that when the nitrogen application rates were the same,slow-release nitrogen fertilizer could significantly increase the yield of wheat by 9.0%compared with the application of urea,mainly due to an increase in the number of harvested ears and the grain weight per ear.When the application rate of slow-release nitrogen fertilizer was reduced,the yield decreased,and so did the net income.When the application rate of slow-release nitrogen fertilizer was 240.0 kg·hm-2,the net income was the highest,reaching 14 494.5 yuan·hm-2.Considering factors such as wheat yield and income,it is recommended that the optimal nitrogen application rate for slow-release nitrogen fertilizer be 240.0 kg·hm-2.关键词
