肥料的配比,用量和施肥时期都会直接影响果树的产量和质量,研究和改进施肥方法,以恢复保持和提高品质,是目前果树栽培管理中最为重要的研究课题之一。为此,我们对苹果、梨进行了定位回归混料比率试验,研究肥料配比,用量及施肥时期,为今后合理施肥提供科学依据。 Fertilizer ratio, dosage and fertilization period will directly affect the yield and quality of fruit trees, research and improve fertilization methods to restore maintain and improve quality, is currently the fruit tree cultivation and management of one of the most important research topics. For this reason, we carried on the experiment of returning the ratio of apples and apples to apples and pears, studied the ratio of fertilizers, dosage and fertilizing period, and provided the scientific basis for rational fertilization in the future.
