Soil improvement method for planting fruit trees

Abstract

The invention discloses a soil improvement method for planting fruit trees, and relates to the technical field of soil improvement. The method is used for solving the problems that soil for planting the fruit trees in the prior art is low in organic matter content and low in fruiting rate. The method comprises the steps of A, green manure planting, wherein a single-cropping green manure planting method is adopted during two years of soil fallow, sweet clovers and vicia villosa are rotated, and the harvested sweet clovers and the vicia villosa are crushed and turned over in the fallow land; B,deep tillage of soil, wherein the soil in step A is subjected to deep tillage, and the deep tillage depth of the soil is 60-90 cm; C, high edges and wide ditches are dug, wherein the land in step B isdivided into a plurality of land strips with the width of 4.5 m, deep ditches are dug in the inner sides of the land strips, the soil of the deep ditches is evenly paved on the outer sides of the land strips to form the high edges, the ground plane of the land strips serves as a reference plane, the depth of the deep ditches is 30 cm, and the height of the high edges is 30 cm. The method has theadvantages that the content of organic matter in the soil is improved, fruit hanging of the fruit trees is facilitated, and waterlogging is prevented; meanwhile, the fruit trees are planted on the high edges, and wide-furrow plantation of shade-tolerant crops increases the land utilization rate.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil improvement method for planting fruit trees. Background technique [0002] The development policy of my country's fruit tree industry is "fruit trees go up the mountain and down the beach, and do not compete with grain, cotton and oil for land", which determines that my country's fruit trees are planted on hillsides, mountainous areas, hills, beaches, tidal flats and saline-alkali land. These places generally have poor soil quality, poor structure and low fertility. Specifically, the organic matter content in the soil is low or extremely low, which is not conducive to the growth and development of fruit trees and the fruit setting rate is low. At present, the soil organic matter content of orchards in northern my country is generally below 1%, and the average content of organic matter in southern orchards is about 1%, which cannot meet the nutrients needed for fru...
