摘　　要：总结了黄土高原旱地苹果园生草栽培的土壤环境效应,包括对土壤有机质的提升效应、对大量元素供应状况的改善以及土壤理化特性的效应;归纳了果园生草栽培对苹果树体生长发育和果品品质、产量的影响,主要正面效应包括抑制营养生长,促进生殖生长,提高产量,提高固形物、糖酸比和硬度等品质指标;分析了生草栽培的果园生态效应;评述了黄土高原旱地果园生草栽培的应用与管理方法,确定了黄土高原旱区果园生草栽培的草种、生草栽培模式以及生草后管理等,为适地推进黄土高原旱地苹果园生草栽培提供思路和参考依据。This paper summarized the effects of pasture-planting in semi-dry region apple orchard in the loess plateau on the soil environment, including the promotion of the organic content, the macro element supply status, and the effect on the soil physiological and chemical characters; outlined the effect of pasture-planting on the growth of apple trees, the quality and quantity of apple fruits including the inhibition of vegetative growth of the apple tree, promotion of the flowering and bearing, and increasing of yield and fruit firmness,soluble substance content and sugar acid ratio. The ecological effect of pasture-planting was also analyzed.The application of pasture-planting was also discussed and the appreciated grass species, pasture-planting mode and the management after planting were recommended. This will put forth ideas and reference for promoting pasture-planting in apple orchard in semi-dry region of the loess plateau.
