Method of planting green manure around fruit trees in apple orchard and alternately ditching to accumulate fertilizer and collect roots

Abstract

The invention relates to a green manuring / fruit tree centered alternate ditching and root-oriented manure accumulation method for an apple orchard. The method is characterized in that by taking the trunk of each apple tree as the center, alternate ditching and manure accumulation is performed around each apple tree, thereby forming a square manure accumulation ditch or a hexagonal manure accumulation ditch around each apple tree. The method provided by the invention has a high and balanced manure utilization ratio, thereby being beneficial to the balanced growth of root systems of the apple trees; the method can promote the balanced growth of the fruit trees and improve the quality balance of apples; and the method can not cause water / soil / manure loss.

Description

technical field [0001] The invention belongs to the technical field of apple planting and fertilization. Background technique [0002] With the continuous expansion of the apple planting area and the continuous improvement of the planting level, the varieties of apples have been continuously optimized, and the quality of apples has also been continuously improved. The current apple planting technology is very mature in terms of pruning, shaping, and cultivation, but there are still deficiencies in field management, which are mainly manifested in "heavy nitrogen, phosphorus fertilizer, light organic fertilizer, potassium fertilizer and micro-fertilizer". The unreasonable ratio leads to soil compaction and poor air permeability, which seriously affects the yield and quality of apples. In order to improve the yield and quality of apples and take the road of sustainable development, it is necessary to adjust the fertilization structure and adopt scientific and reasonable fertil...

This method is beneficial to soil fertilization, root growth and fertilizer absorption between fruit tree rows, but it is not conducive to soil fertilization, root growth and fertilizer absorption and utilization between fruit tree rows. After long-term accumulation, fruit tree roots will grow unbalanced , resulting in unbalanced fruit tree branching, branch growth and fruiting, affecting the balance of apple quality

What's more unfavorable is that continuous straight ditches will form waterlogging ditches, which will cause severe waterlogging during the rainy season. If the waterlogging time is too long, the roots of the trees will rot, which is not conducive to the normal growth of fruit trees, especially on slopes, and in ditches. The water continuously flows to the lower place to scour, which causes the loss of water, soil and fertilizer, so another drainage system has to be installed

The second way is to open a shallow ditch around the fruit tree to fertilize. Generally, the ditch is about 10 cm deep. Sprinkle chemical fertilizers to irrigate with water. After the water dries up, return the soil to fill it up. In addition, after the fertilizer is mixed with the soil, some nutrients are fixed by the soil, and the utilization rate of the fertilizer is reduced
