The invention provides a self-circulation peach orchard grass growing covering cultivation method. The technical problems that in the prior art, the peach orchard circulation updating cost is high, and the fruit tree growth condition is poor are solved. The method comprises the following steps: sowing medicago sativa or astragalus sinicus among peach tree rows; after the grass seeds are mature and 5-10 days before the fruit expansion period of the peach trees is started, light-proof and water-permeable gardening ground cloth is laid in an overhead mode 20-30 cm away from the ground, and weed suppression and decay promotion are achieved; the ground cloth is removed after the fruits are harvested, so that grass seeds naturally falling off in the last year germinate and regenerate in a light-transmitting manner, and a'cloth covering-cloth uncovering 'closed-loop cycle is formed. Zero-cost self-circulation (the germination rate is larger than or equal to 92.3%) of grass seeds is synchronously achieved, the decomposition fertilizer efficiency is matched with the peach tree fertilizer requirement peak (the soluble solid content breaks through 13.21%, and the weight of a single fruit is 236.12 g), and the synergistic advantages of soil improvement and acid reduction (organic matter content is 33.09 g / kg) of alfalfa and nitrogen fixation and sugar extraction (soluble sugar content is increased by 12.61%) of astragalus sinicus are exerted. The problems of year-by-year reseeding, fertilizer competition between grass and trees and fertilizer efficiency lag in the traditional grass growing technology are solved, the planting cost is reduced, and the dual improvement of ecology and quality is realized.
