摘　　要：以自然生草有机覆盖区域(秋冬季辅以撒播紫花光叶苕子种子)为试验对象,清耕制区域作为对照,研究自然生草有机覆盖对土壤含水量、土壤容重、土壤温度、桃树春梢生长、桃树品质的影响,结果表明,在低纬度高原地区的雨养桃园,自然生草有机覆盖可以提高土壤含水量、降低土壤容重、降低土壤温度、促进桃树春梢的生长,自然生草有机覆盖区域桃树果实的产量、总糖含量、维生素C含量都显著高于清耕制区域的桃树。The organic mulching area of natural grass(supplemented by sowing Vicia Villosa Roth var.glabrescens seeds in autumn and winter)was used as the test object,and the cultivation area of clear tillage was used as the control to study the effects of organic mulching method of natural grass on soil water content,soil volume density,soil temperature,spring shoot growth of peach trees,and peach tree quality.The results showed that,in the rain-fed peach orchard of the low latitude plateau area,organic mulching of natural grass could improve soil water content,reduce soil bulk density,reduce soil temperature,and promote the spring shoot growth of peach trees.Peach fruit yield,total sugar content and vitamin C content in the organic mulching area of natural grass were significantly higher than those of peach trees in the clear tillage area.
