减氮配施有机肥对华浙优210产量与米质的影响
Effects of Reduced Nitrogen Application Combined with Organic Fertilizer Application on Yield and Quality of Huazheyou 210
摘要
Abstract
In order to investigate the effects of nitrogen reduction combined with the application of organic fertilizer on the yield and quality of high-quality rice variety Huazheyou 210,providing theoretical and technical guidance for high-yield,high-quality,and efficient cultivation of high-quality rice.Field experiments were conducted in Lanxi and Fuyang,Zhe-jiang Province,in 2022,using a completely randomized block design with three nitrogen application treatments:no nitrogen fertilizer treatment(control,T0),chemical fertilizer application treatment(T1),and nitrogen reduction combined with the application of commercial organic fertilizer treatment(T2).The growth,yield and quality of rice in different treatments were compared and analyzed.The results indicated that,compared with T1 treatment,T2 treatment could reduce unproductive tillers,and increase the percentage of productive tillers,increase leaf area duration and crop growth rate during the middle and late growth periods,increase root oxidation activity and leaf photosynthetic rate during the grain filling period,and in-crease the rate of head milled rice and gel consistency,reduce the rate of chalkiness grain,chalkiness degree and protein content of rice.The yield of nitrogen reduction combined with organic fertilizer treatment was the same as that of conven-tional chemical fertilizer treatment,and had higher nitrogen use efficiency,and could improve rice quality.关键词
