测土配方施肥对春小麦产量和品质的影响

本文的试验结果表明,测土施肥与习惯施肥相比,在低肥力土壤上增产23—25％,每亩增加纯收入13—16元;在高肥力土壤上增加纯收入5—13元。测土施肥春小麦籽粒的粗蛋白质和粗脂肪的含量都比较高。因此,测土施肥是一项增产、增收、节肥的先进施肥技术,有推广应用的价值。

Effect of Soil Test and Fertilizer Recommendation on Yield and Quality of Spring Wheat

The soil test and fertilizer recommendation method could increase yield by 23—25%: the net income was 13—16 yuans per mu more than that of the routine method in the low P supplying soils, and 5—13 yuans per mu more in high P supplying soils. The contents of crude proteins and crude fats in spring wheat seeds were higher. Therefore, this method is an advanced fertilization technique, and may thus be used widely.
