Dry grass orchard covering grass is an effective measure to improve soil water storage capacity and reduce soil water and soil loss and surface water evaporation. It can be used with wheat straw, smashed straw, local weeds, etc., and the thickness of the grass is 15-20 cm. In order to prevent fire, it can be carried out in the rainy season. The soil is pressed on the soil, and after the grass is rotted, it is turned into the soil and covered with new grass. The grass cover has the disadvantages of the roots of the winter jujube tree seedlings. It can be fertilized every year by deep fertilization, rooting down, and paying attention to the prevention and control of pests in the grass to eliminate the pests and germs that overwinter in the grass.

Planting green manure crops in dryland orchards and turning them on site is a good strategy to increase soil organic matter content and store water to improve drought resistance. Spring cover mulch can be implemented, and green manure can be planted before the rainy season to solve the contradiction between green manure crops and fruit trees.

The annual green manure crop can be selected from mung bean or tianjing. It is planted before the rainy season. After the rain, it can be emerged. After the rain, the seedlings are planted early and the fresh produce is high. In order to increase the yield of grass, in the growth period of green manure crops, combined with rainfall, topdressing nitrogen fertilizer and phosphorus and potassium fertilizer, when the mung bean or tianjing flowering, it will be pressed on the spot. It is also necessary to prevent the growth of the green manure crops in the second weeds of winter jujube seedlings.
