播期密度氮肥运筹对‘罗麦10号’产量的影响
Effects of different nitrogen fertilizer treatments sowing date density on yield of'Luomai-10'
摘要
Abstract
To study the effects of sowing date,density and nitrogen fertilizer on the yield of'Luomai-10',the effects of sowing date,the test of planting density and nitrogen management on grain yield and yield components had been set up.The results showed that sowing date and density affected grain yield significantly,the average yield of November 5th (S2) was the highest (7 510.20 kg/hm2) and significantly higher than November 15th(S3)and November 25th(S4).Early sowing and lower density treatment could get higher yield.When the nitrogen application levels were 210 kg/hm2 and 270 kg/hm2,the dressing ratio was 6∶ 4,the yields were the highest;when the nitrogen application level was 330 kg/hm2,the yield of dressing ratio treatments 7∶3 was highest.When the sowing date was November 5th,the basic seedlings was 210 × 104/hm2,the nitrogen application was 210 kg/hm2,the dressing ratio was 6∶ 4,'Luomai-10'could attain an higher yield.关键词
