【摘要】 本文以新疆南部苹果园为对象,设置生草、覆草、免耕、清耕四种处理,研究不同管理方式对苹果产量和品质的影响。结果表明,各处理对产量影响表现为生草>覆草>免耕>清耕,生草和覆草分别比免耕提高4.44%和1.68%,比清耕提高6.52%和3.70%;四种管理方式以覆草处理对果实单果重促进作用最明显,生草处理能显著改善果实着色情况,各项果实外观品质指标均以清耕处理表现最差,可溶性固形物、可溶性糖、可滴定酸三项指标以覆草处理表现最佳,生草次之。免耕处理对果实Vc含量的增加最为显著。综合各项指标,推荐覆草和生草为南疆干旱区适宜的果园管理方式。更多还原

【Abstract】 The study,using apple orchards in southern Xinjiang as target and setting up four treatments as mulching,growing grass,no-till and clean till,investigated the effects of the treatments on apple yield and quality.Results showed that different treatment effects on apple yield followed an order of growing grass>mulching>no-till>clean till.The treatments of growing grass and mulching produced 4.44% and 1.68%of higher apple yield than the of no-till treatment,and 6.52%and 3.70%of higher yield than clean till treatment.Mulching had the most significant effect on promoting fruit weight.Growing grass significantly improved the color of the fruit.The clean till treatment resulted in the worst fruit appearance. Mulching treatment had the highest soluble solids,soluble sugar and titratable acids and followed by growing grass.No-till had the most significant effect on increasing fruit Vc.Considering all the indicators, we recommended that mulching and growing grass can be the appropriate orchard management practices in the southern arid area of Xinjiang.更多还原
