有机液肥施用对水稻增产效应的分析

以“赣晚籼37号”(926)为材料,研究了卢博士有机液肥不同施用方法对水稻产量的影响,并对水稻产量构成因素进行了分析。施用卢博士有机液肥4个处理的产量明显高于不施卢博士有机液肥的处理,而且施用卢博士有机液肥的4个处理中,不同的用量次数之间也有明显的差异。结果表明,卢博士有机液肥在水稻上的使用具有显著的增产效应。增产原因主要在于有效穗、结实率、穗粒数和千粒重的增加,且增幅最高的达12.15%。

Analysis on Effects of Organic Liquid Fertilizer on Rice Yield

Effects of different application methods of Luboshi organic liquid fertilizer on rice yield and yield components were studied by using "Ganwanxian 37"(926) as tested material.The rice yield of four treatments with applying Luboshi organic fertilizer was higher than that of the treatment without applying the fertilizer.There was significant difference among the four treatments with application.So the results showed that applying Luboshi organic fertilizer had significant yield-increasing effect on rice.According to the results,the increase of yield was mainly due to the increase of effective panicles,setting rate,grains per panicle and 1000-grain weight.What's more,the highest yieldincreasing rate could reach 12.15%.
