苹果园有机肥替代化肥效果分析

Analysis on the Effect of Organic Fertilizer Replacing Chemical Fertilizer in Apple Orchard

为探究有机肥替代不同比例化肥(基肥)对苹果产量的影响,开展苹果园有机肥替代化肥试验,设置了有机肥替代化肥(基肥)20%、40%、60%和100%处理,并分析了不同处理的苹果产量、投入产出情况以及不同处理的化肥偏生产力(PFP)。结果表明:有机肥替代化肥(基肥)能够提高苹果产量,提高商品果率,有机肥替代40%化肥(基肥)和有机肥替代60%化肥(基肥)均能够显著提高苹果产量。综合分析,有机肥替代40%化肥(基肥)的667 m^(2)平均纯收入最高,且化肥用量减少19.5%,提高了化肥偏生产力,能够实现化肥减量增效。

In order to explore the effect of organic fertilizer substitution for chemical fertilizer(base fertilizer) on apple yield, the experiment of organic fertilizer substitution for chemical fertilizer in apple orchard was carried out.The treatments of 20%, 40%, 60% and 100% organic fertilizer substitution for chemical fertilizer(base fertilizer)were set up. The apple yield, input and output of different treatments and the partial factor productivity of fertilizer(PFP) under different treatments were analyzed. The results showed that the substitution of organic fertilizer for chemical fertilizer(base fertilizer) could increase apple yield and commercial fruit rate. The substitution of organic fertilizer for 40% chemical fertilizer(base fertilizer) and 60% chemical fertilizer(base fertilizer) could significantly increase apple yield. Comprehensive analysis shows that the average net income per 667 m^(2) of organic fertilizer replacing 40% chemical fertilizer(base fertilizer) is the highest, and the amount of chemical fertilizer is reduced by19.5%, which improves the PFP of chemical fertilizer and can achieve chemical weight Loss and increase efficiency.
