摘要
通过对水稻施用不同量级穗肥来研究其对水稻产量的影响,确认穗肥不同施用量的增产效果,选择最佳施用量。结果表明,适当增加穗肥施用量对提高水稻产量有较好的作用,不同穗肥施用量增产率分别为2.8%～7.7%,效益增加35.2～98.8元/667 m2。其中施用尿素7.5 kg/667 m2、硫酸钾4.4 kg/667 m2的处理增产、增收效果最明显。
In order to select the best amount, the test analysed the yield-increasing effect under the different anoumt of panicle fertilizer, the results indicated that opportune panicle fertilizer can increase the yield and its yield increase by 2.8% to 7.7% with a benefit increase by 35.2-98.8 yuan/667 m^2, the best dosage of urea and potassium sulfate which were 7.5 kg/667 m^2 and 4.4 kg/667 m^2 can receive obvious income.
