超级稻Y两优5867不同施氮量、施肥配比及栽插密度试验

Test on Nitrogen Application,Fertilization Ratio and Planting Density of Super Rice 'Y Liangyou 5867'

在龙岩市永定区进行氮肥不同施用量、氮磷钾不同比例配比和不同栽植密度试验,结果表明:(1)氮肥不同施用量试验(N∶P2O5∶K2O为1∶0.3∶0.75)以180kg·hm^(-2)产量最高;(2)氮磷钾不同比例配比试验以氮磷钾1∶0.5∶1比例为佳,综合性状好,产量最高,产量为10.33t·hm^(-2);(3)不同栽植密度试验产量最高的处理为插植密度23.3cm×26.6cm,产量为10.21t·hm^(-2)。

A test on different nitrogen application,different proportions of nitrogen,phosphorus and potassium,and different planting density were conducted in Yongding District of Longyan City.The results showed that:(1)The yield of 180 kg·hm-2 N fertilizer application was the highest in the test of different application of nitrogen fertilizer(N∶P 2O 5∶K 2O was 1∶0.3∶0.75);(2)The ratio of nitrogen,phosphorus,potassium of 1∶0.5∶1 was the best in the test of different proportions of nitrogen,phosphorus and potassium,the comprehensive character of rice was good and the yield was the highest,which was 10.33 t·hm-2;(3)In the test of different planting density,the highest yield was 10.21 t·hm-2 while the planting density was 23.3 cm×26.6 cm.
