水稻稀植高产栽培不同施肥方法研究

The Research of Different Methods of Fertilizing of Rice using Thin Planting Density with High Yield

为探索水稻稀植高产栽培的最佳施氮量,开展了水稻稀植高产栽培施肥试验,为我省水稻稀植高产栽培提供科学依据。本试验采用宜香优2115为试验品种,不同的施肥方式配置不同的施肥量进行研究。结果表明:施纯氮和纯钾分别为13kg/667m^2和15 kg/667m^2时的处理产量表现最高,为770.67 kg/667m^2,全生育期最短,综合比较各处理的经济性状,表现也较为优异。其次是施纯氮和纯钾分别为15 kg/667m^2、17 kg/667m^2的处理产量排第2。

To find the best of sparsely-planted rice high-yield cultivation n application rate,conducted sparsely-planted rice high-yield cultivation fertilization experiment,provide scientific basis for our province sparsely-planted rice high-yield cultivation.In this experiment,the study of different fertilizing methods was carried out by using Yixiangyou2115.Experimental results show that application nitrogen and pure potassium is13kg/667m respectively and the processing of15kg/667m yield the highest(770.67kg/667m),the shortest in the whole stages,comprehensive comparison of economic characters of each process were also more excellent.The second is that the nitrogen and the pure potassium are respectively15kg/667m and17kg/667m respectively.
