摘  要：
以往从减少病虫害越冬基数出发,果园落叶多清除或销毁。但落叶是有机物,可改清除为树下埋施,以有利于改良土壤。4年的落叶还田结果表明,土壤有机质含量比对照增加10.7%～14.5%,土壤含水量增加8%～12%,苹果着色增加11%～15%,可溶性固形物含量增加0.7%～2.2%,苹果产量增加6.9%～10.5%,收入增加9.2%～16.1%。可见,每年的落叶量虽然不多,但年复一年积累起来,其改土和增产提质效果是明显的。

摘  要：
In the past,starting from the winter base of reducing diseases and insect pests, orchard leaves were removed or destroyed. But the leaves are organic and can be removed and buried under the trees to help improve the soil. 4 years of defoliation returning results showed that soil organic matter content is 10.7% ～14.5% higher than the control,soil water content increased from 8% to 12%,apple coloring increase 11% ～15%,the increase of soluble solids content of 0.7%～2.2%,apple yield increased by 6.9% to 10.5%,revenue increased 9.2%～16.1%. It can be seen that the annual amount of fallen leaves is not large,but it has been accumulated year after year. The effect of soil improvement and yield increase and quality improvement is obvious.
