苹果有机无机配比施肥的最佳肥效探讨

针对临猗县果农在苹果施肥上有机无机肥料盲目配比的现状,进行了苹果有机无机肥料的配比试验。结果表明,有机无机肥料按照1∶1投资金额配比施用的处理,单果质量最高,较最低处理提高11 g;单株产量提高4.5 kg,含糖量提高1.0百分点,果径<70 cm的比例降低了5.6百分点,>80 cm的比例增加5.3百分点,平均净增效益10 719元/hm2。针对不同肥力水平提出针对性的施肥建议,在提高苹果肥料利用率的同时实现提质增产,为完善县域苹果测土配方施肥技术体系提供一定依据。

Approach to Best Fertilizer Efficiency of Organic and Inorganic Combined Fertilization on Apple

For present blind situation of organic and inorganic fertilizer of apple grower,the ratio of organic and inorganic fertilizer experiment of apple was taken.The results showed that,organic and inorganic fertilizer treatment with 1:1 amount of investment ratio,single fruit weight was the highest than the other processing by 11g,yield per plant improved 4.5 kg,sugar content increased 1 percentage point,the proportion of fruit diameter <70cm ratio decreased by 5.6 percentage points,while that >80 cm increased 5.3 percentage points,the average net profit was 10 719 Yuan/hm2.According to the different fertility level for fertilization suggestion,to improve the utilization rate of fertilizer and to achieve quality apple production,the paper provided the basis for measuring soil formula fertilization technique system to perfecting the apple planting in Linyi county.
