Abstract

Abstract: 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.

Key words: natural grass, low latitude plateau area, peach orchard, soil properties, Yunnan Province
