Peach orchard soil conditioner and application thereof

Abstract

The invention provides a peach orchard soil conditioner and application thereof. The peach orchard soil conditioner comprises biomass charcoal, and the biomass charcoal comprises, by mass, 0.76-1.35% of nitrogen, 0.68-1.25% of phosphorus, 1.47-2.08% of potassium, 0.34-0.57% of sulfur, 0.37-0.66% of calcium, 1.04-1.32% of magnesium, 40.8-55.4% of organic carbon and 13.6-42.1% of inorganic carbon. The pH value of the soil conditioner is 8.3-9.8. The peach orchard soil conditioner is high in adsorption affinity, can greatly improve the granular structure, porosity and air permeability of soil, provides survival space for beneficial soil microorganisms, effectively solves the continuous cropping problems of soil acidification, nutrient loss and unbalance, microbial population unbalance and the like, and greatly increases the peach seedling transplanting survival rate.

Description

technical field [0001] The invention belongs to the technical field of agricultural soil improvement, and in particular relates to a peach orchard soil conditioner and its application. Background technique [0002] Peach is a popular fruit. According to the 2014 China Agricultural Yearbook statistics, in 2013 my country’s peach planting area was 765,900 hectares, with a total output of 11.9241 million tons, accounting for 61.59% of the world’s major peach-producing countries. The planting area and total Production is still rising steadily. [0003] The survey results show that the general economic life of peach trees is only 12-15 years. When the peach orchard removes old trees and replants new peach trees, the root meristems of the newly planted peach trees are poor, the growth of young trees is stagnant or weak, the plants are short, the leaves are chlorotic, the branches are gummed, the fruiting is delayed, the resistance and the continuous cropping survival rate are shar...

Problems solved by technology

[0004] Affected by limited land resources, regional brand benefits, and industrial chain advantages, it is difficult to implement methods such as opening new peach orchards or land rotation in actual production. New seedlings must be continuously planted on the soil that has been cut down from old peach trees. The problem of continuous cropping obstacles is prominent. It has seriously threatened the sustainable development of the peach industry and has become a bottleneck problem restricting the development of peach production in some areas.

[0005] The reasons for continuous cropping obstacles in peach trees are ve
