豫南水稻“3414”肥效试验

"3414"Fertilizer Effect Experiment of Rice in Southern Henan

为探明珍珠糯最佳经济效益时的氮、磷、钾需求量,为珍珠糯在信阳地区的高效栽培提供肥料技术支撑,本文开展了珍珠糯水稻"3414"肥效试验,采用"3414"完全实施方案,设氮、磷、钾3个因素,4个处理水平(0、1、2、3),14个处理,3次重复。结果表明,3种肥料对珍珠糯产量影响表现为氮>磷>钾;施用尿素392 kg/hm^2、过磷酸钙750 kg/hm^2、氯化钾210 kg/hm^2处理平均产量最高,达10361.26 kg/hm^2;最佳经济效益施肥方案为尿素261.16 kg/hm^2、过磷酸钙328.5 kg/hm^2、氯化钾223.1 kg/hm^2。

In order to explore the demand of N,P and K for the best economic benefit of Zhenzhunuo,and provide fertilizer technology support for the efficient cultivation of Zhenzhunuo in Xinyang area,"3414"full implementation fertilizer effect experiment was carried out.In this study,3 factors(N,P and K)and 4 treatment levels(0,1,2,3)were set,and there were 14 treatments and 3 replication.The results showed that the order of 3 fertilizer effects on the yield of Zhenzhunuo were N>P>K.The average yield was the highest(10361.26 kg/hm^2),when applying urea 392 kg/hm^2,superphosphate 750 kg/hm^2 and potassium chloride 210 kg/hm^2.The best economic benefit scheme is urea 261.16 kg/hm^2,superphosphate 328.5 kg/hm^2 and potassium chloride 223.1 kg/hm^2.
