| 摘 要： | 为探讨丹江口库区麦套稻新型耕作方式的适宜施肥量,采用“3414”肥效试验方案研究了氮、磷、钾施肥对水稻产量、生产效益和养分利用的影响.结果表明,麦套稻系统水稻产量的形成主要决定于单位面积穗数和穗总粒数；氮磷钾合理施肥可显著提高产量,在N、P2O5和K2O施用量分别为168.0、75.0、90.0 kg/hm2时产量最高... |

| Abstract: | '3414' field trial was adopted to study the appropriate rate of fertilizer application and efficiency of fertilizer usage in relay cropping rice with wheat,a new cropping system in Danjiangkou region.Results showed that the yield of relay cropping rice was mainly determined by the effective panicle number per hectare and total grains per panicle.Appropriate application of N,P and K fertilizer increased yield significantly and farmer's economic income.The highest grain yield reached up to 6 889 kg/hm2 when t... |
