Due to the drought in recent years, the cost of watering in orchards has increased and the burden on farmers has increased. To this end, the orchards cover grass. Practice has proved that the orchard-covered grass is a technical measure to preserve and increase fertility in dry land orchards, improve fruit quality, and achieve stable production and high yields. 1. Coverage time can be all year round, preferably after spring, wheat harvest or autumn harvest, preferably in a season rich in grassland. Generally, it is covered when the ground temperature reaches 20°C in sandy soil and dry thin soil at 20 cm, and it is suitable when the ground temperature at 20 cm soil layer in clay ground and fertility reaches 22°C. 2. Types of grass cover, amount of all kinds of weeds, leaves, crop stalks and chopped firewood can be. Spring covered hay and summer pressed grass. Partial grass cover, 1,000 to 1200 kilograms of hay per mu, fresh grass 2500 to 3500 kilograms; grass covered the whole park, hay 2000 to 2500 kilograms per acre, fresh grass 5000 ~ 6500 kg. Grass should be short to facilitate coverage and rot. In spring, the grass must be pressed. The extent of partial grass-covering is controlled at the place where the root system is distributed, and it can be just outside the canopy. 3. Before covering the grass with fertilizing and mulching grass, combine with deep turning or squat irrigation. According to the age of trees, apply 0.3 to 0.6 kg of nitrogen fertilizer per plant to meet the requirement of microbial decomposition of organic matter on nitrogen fertilizer. 4. Covering the Grass Straw stalks or orchard weeds are cut into 15-20 cm long sections and spread evenly between rows of orchard rows and under tree trays. The thickness is 15 to 25 cm. After spreading, the grass is pressed onto the grass. Soil to prevent wind blow and prevent fire. The orchard with a thin soil layer and poor fertility can be combined with deep trenching and covering grass, and once over three years, it can be turned over once. 5. Apply fertilizer after grass-covering and gently turn it after autumn. When applying basic fertilizer in autumn, do not turn grass into the ground. Grass should be stamped every year. After 4 to 5 years deeper, turn over the grass and cover the grass when topdressing. The method of applying acupuncture points was used for fertilizing and watering immediately after fertilization. Prior to the “shocking†of the turfgrass garden, 600-800 times more phoxim was sprayed under the trees to eliminate overwintering pests and overwintering eggs concentrated in the clumps. In addition, during the dry season in winter and spring, we must pay attention to the fire protection in the turfgrass garden, and prohibit smoking and burning of discarded debris in orchards.
