New method of fertilizing fruit trees - hole storage fertilizer film

The method is to bury a certain amount of straws in the concentrated distribution area of ​​the fruit tree, and cover the mulch film, thereby temporarily storing the applied fertilizer water, reducing the loss, gradually releasing nutrients and water, and stabilizing the annual supply of fruit trees. It can obviously improve the growth and development of fruit trees and achieve the purpose of increasing production and strengthening trees. Its advantages are to improve the early spring ground temperature, save water and fertilizer, improve the survival rate of young trees, increase the yield of strong trees, low cost and significant benefits. This technology can be used on apples, pears, apricots, plums, etc., usually after the fruit trees are germinated to flower each year.

The specific operation is as follows: 4 to 8 holes can be set for the big tree, and 2 points for the young tree. The general hole diameter is 25 to 30 cm, the depth of the hole is 35 to 45 cm, and the bundled grass handles are used (for straw or weeds). Yes, the grass bundles are 15 to 25 cm in diameter and 30 to 35 cm in length, soaked in water before burying) and vertically bundled into the holes. Apply calcium superphosphate at the bottom of the hole, 50-100 grams per hole. When backfilling, it should be solid. When the top of the grass is covered with soil to 1 cm, 50-100 grams of urea should be applied. If ammonium bicarbonate is applied, it should be backfilled. Apply 20 cm on the ground. Then fill the soil, then water, and then cover the soil, after the hole is buried, it is 1-2 cm below the ground, forming a small sputum to accumulate water. Then cover the mulch on the top, and put a small hole in the mulch at the center of the hole to press a small stone to collect rainwater and water.
