The method of mulching and mulching with fertilizer in the fruit tree hole is to bury a certain number of straws in the concentrated distribution area of ​​the absorbing roots of the fruit tree and cover it with plastic film, thereby temporarily storing the applied fertilizer and water, reducing loss, and gradually releasing nutrients and water. Stabilize the supply of fertilizer and water throughout the year, significantly improve the growth and development of fruit trees, and achieve the purpose of increasing yield and growing trees. It is usually carried out after the fruit tree sprouts to flower every year.
The specific operation is as follows: the big tree can be set with 4 to 8 holes, and the young tree can be set with 2 holes. The general hole diameter is 25-30 cm, and the hole depth is 35-45 cm. Yes, the straw is bundled with a diameter of 15-25 cm and a length of 30-35 cm, soaked in water before burying). Apply superphosphate at the bottom of the hole, 50-100 grams per hole, and be firm when backfilling the soil. When the top of the grass is covered with soil to 1 cm, apply 50-100 grams of urea. Apply at 20 cm. Then fill the soil, then water, and then cover the soil. After the hole is buried, it will be 1 to 2 cm below the ground, forming a small depression for water accumulation. Then cover the mulch with a small hole in the mulch at the center of the hole and press a small stone to collect rainwater and water.
