| 摘 要： | 研究了太行山低山丘陵区苹果园生草栽培对土壤和树体养分的影响,结果表明,生草处理果园0~40cm土壤有机质含量较对照提高12.87%,全N提高10.31%,但全P和全K略低于对照;生草处理苹果各器官N素含量均高于对照,而叶和果实中P、K的含量略低于对照。说明生草果园苹果和紫花苜蓿在P、K吸收上存在着一定的竞争。

| Abstract: | A 6-year continuous experiment on effects of sod culture on nutrient content of soil and apple tree was conducted in the drought hilly region of Taihang mountain. The results showed that the organic matter in 0-40cm soil of sod culture treatment increased by 12.87%, total N by 10.31%, N content in each apple tree organ separately higher than those in tree with clean tillage. But total P total K of 0-40cm soil and content of N and K of leaves and fruits were lower than that of treatment with clean tillage. This indicated that there was slight competition in P and K intake between apple tree and alfalfa in sod culture orchard. |
