为了进行果树配方肥肥料研究,筛选出适合当地的最佳配方,进一步修正和完善果树施肥技术,为大面积示范推广新的测土配方施肥技术提供科学依据,笔者于2015~2016年在陕西省合阳县甘井镇西牛庄苹果园进了新型肥料不同使用量研究试验,结果表明:优化处理和新型肥料不同用量处理对苹果都有增产作用,优化处理和农民常规施肥相比,亩增产474.5kg,增产率15.9%、投入产出比为1∶6.5;株施4kg、6kg、8kg和农民常规施肥相比,分别增产275.2kg、428.5kg、562.3kg,增产率分别为9.2%、14.4%、18.9%。投入产出比分别为1∶4.1、1∶3.6、1∶3.2。在新型肥料不同施用量中,株施8kg增产效果最好,株施4kg投产比最高。
In order to carry out the fruit fertilizer fertilizer research, screening out the best for the local formula, and further amendments and improve the fruit tree fertilization technology for large-scale demonstration of new soil testing and fertilizer technology to provide a scientific basis, the author in 2015 to 2016 in Shaanxi Province Heyang County Ganjing Township West Niu Zhuang Apple Orchard into the new use of different doses of fertilizer research and experimental results show that: Optimum treatment and application of new fertilizers have different effects on apples have increased yield, optimization and farmers conventional fertilization compared to an increase of 474.5 mu kg and yield increase rate of 15.9% and input-output ratio of 1: 6.5. The yield of 4kg, 6kg and 8kg was increased by 275.2kg, 428.5kg and 562.3kg, respectively. The yield was 9.2% and 14.4% , 18.9%. Input-output ratio was 1: 4.1, 1: 3.6, 1: 3.2 respectively. In the new fertilizer application rates, the plant yield 8kg the best yield, plant 4kg put into operation the highest.
