1, do grass handle. Use corn (2460, 5.00, 0.20%) straw, wheat straw, or rice straw, etc., to bind straws (15-25 cm in diameter and 30-35 cm long) (to be fastened tightly). Soaked in 5%-10% urea solution. 2, digging storage and raising points. In the canopy projecting edge, 50-70 cm inwards, dig a depth of 40 cm, and a stocking hole slightly larger than the diameter of the grass stem. According to the size of the tree crown, the number of stocking holes was determined, and there were 4 holes with a crown diameter of 3.5-4 meters; 6-8 holes with a diameter of 6 meters were evenly distributed around the roots of trees. 3, buried grass. Put the grass stem in the center of the hole and surround it with soil mixed with organic manure (solids 5 kg per hole, add 150 g superphosphate, 50-100 g urea or compound fertilizer) and pour In water, each hole is covered with a film of 1.5-2 square meters, and the edges of the film are tightly packed with soil. The center is putting a small hole on the upper end of the grass and blocking it with stones or soil so that it can be topdressed and watered in the future. 4, generally in the post-flower (mid-May mid-term), the new shoots stop long-term (in mid-June) and fruit picking three periods, each hole to apply 50-100 grams of urea or compound fertilizer, the method is: put the fertilizer in The top of the grass, then watered about 3.5 kilograms. In the rainy season, the mulching film can be removed to store rainwater in the cave. The general storage and maintenance of acupuncture points can be maintained for 2-3 years. The grass should be replaced once a year and the damaged plastic film should be promptly replaced. When setting up the storage point again, the position should be changed, and the entire park should be gradually improved.
