羽扇豆还田与氮肥配施对水稻产量、氮肥利用率和土壤肥力的影响
Effects of Lupine Return and Nitrogen Fertilizer on Rice Yield,Nitrogen Use Efficiency and Soil Fertility
摘要
Abstract
The rice was used as the experimental material to conduct a 2-year field experiment.Two treatments including lupine return amount(M)and nitrogen application amount(N)were set up.Two levels of lupine application were set at 0 kg/hm2 and 18 t/hm2 for M treatment,and six levels of nitrogen fertilizer application were set at 0 kg/hm2,90 kg/hm2,135 kg/hm2,180 kg/hm2,225 kg/hm2 and 270 kg/hm2 for N treatment,The effects of lupine application and nitrogen fertilizer application on rice yield,nitrogen fertilizer utilization rate and soil physical and chemical properties were studied.The results showed that after lupine application,the effective panicles per plant,total grains per panicle and 1000-grain weight of rice all increased.The rice yield of treatment(MN135)with 135 kg/hm2 nitrogen fertilizer application combined with lupine return application 18 t/hm2 was significantly higher than that of other treatments,increasing by 25.6%to 34.0%compared with the MN0(CK2)treatment.Lupine application could increase soil pH and soil organic matter content.The contents of available nitrogen,available potassium and organic matter in the MN135 treatment were the highest among all treatments,increasing by 35.4%to 90.2%,31.4%to 39.1%and 10.6%to 15.0%respectively compared with the CK2 treatment.Considering all factors,the combination of 18 t/hm2 lupine return application and 135 kg/hm2 chemical nitrogen fertilizer application was the optimal combination,which could be recommended as a fertilization model for sustainable and stable high-yield rice production and soil nutrient improvement.关键词
