Fruit tree perforating deep layer fertilizing method

Abstract

The present invention provides a method for deep fertilizer-application of the fruit tree by punching holes. According to the diameter of the crown of the fruit tree, a cavity hole with the diameter of 20 cm and the depth of 40 to 50 cm is punched every one meter on the circumference 20 cm to 30 cm outside the drip line of the crown range of the tree body, and then according to the growth of the fruit tree in different seasons, the fertilizer is put into the hole and then the fruit tree is watered. The fertilizer released by the present invention is the nitrogenous fertilizer, the phosphorus fertilizer, the potash fertilizer and the organic fertilizer; the ratio between the total quality of the nitrogenous fertilizer, the phosphorus fertilizer and the potash fertilizer and the diameter of the tree crown for every fruit tree is 1m / 5kg to 1m / 6kg; and the ratio of the nitrogenous fertilizer, the phosphorus fertilizer and the potash fertilizer is 3 / 4 / 2. The method of the present invention induces the root of the fruit tree to be deepened in the earth to absorb the nutrition and the water, thereby guaranteeing the effective absorption of the fertilizer, increasing the drought-resistant ability of the fruit tree, strengthening the growth and improving the yield.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and relates to a fertilization method suitable for perennial fruit trees on hillsides and flat lands, in particular to a method for deep-layer fertilization of fruit trees. Background technique [0002] At present, the fertilization method in the cultivation process of perennial fruit trees on hillside and flat land is mainly to apply various required fertilizers to the roots of fruit trees during the growth period of fruit trees. The disadvantage of this method is that the orchard has been operated for many years, and the soil is compacted due to watering. When fertilizing, it is difficult for the root system of the tree to absorb nutrients, resulting in loss of fertilizer, and at the same time causing further compaction and hardening of the soil and environmental pollution. Therefore, the fertilization method in the prior art is costly and wasteful, and the growth of the tree and...

The disadvantage of this method is that the orchard has been operated for many years, and the soil will be compacted due to watering.

When fertilizing, it is difficult for the root system of the tree to absorb nutrients, resulting in loss of fertilizer, and at the same time causing further compaction and hardening of the soil and environmental pollution. Therefore, the fertilization method in the prior art is costly and wastes a lot. not obvious
