Method for improving orchard soil

Abstract

The invention discloses a method for improving orchard soil. The method is characterized by comprising a step (1) of a high temperature disinfection method, wherein lime nitrogen of 70-80 kg and shattered wheat straw of 500-1000 kg per 667 square meters are applied during June to August after seedlings of previous crops are pulled up, furrows with the depth of 30 cm are ditched by rotary tillage, leveling, ridging or row spacing of the crops, the wheat straw or corn stalk of 3000 kg, ammonium bicarbonate of 50 kg, poultry dung of 5-6 cubic meters per 667 square meters are applied, surface soil covering is performed to form a ridge, a greenhouse film is sealed, a mulching film is covered tightly to perform irrigation, 500-1000-fold abamectin liquor of 200 milliliters per plant is utilized to irrigate roots after 15-20 days of insolation and high temperature processing and entering the greenhouse, and the effect for preventing soil-borne disease is good, and a step (2) of irrigation salt-leaching method, wherein the greenhouse is fully loaded with fresh water during rotation of crops and when the soil is not used to form accumulated water of 3-5 cm, the water is discharged from drainage ditches after soil salinity is dissolved fully, and the salinity in the soil is reduced effectively.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a method for improving orchard soil. Background technique [0002] Fruit trees play an important role in the national economy and people's livelihood. Our country has long implemented the strategy of going up the mountain and down the beach, and not competing with grain and cotton for land. Most of the orchards have poor soil, low soil organic matter content, poor soil aggregate structure, inappropriate soil pH, and poor water and fertilizer retention. nutritional deficiencies. Therefore, improving the soil quality of the orchard is the key to making the fruit trees high-yield and high-quality, and the orchard sustainable development. [0003] At present, the soil quality of orchards in my country is facing serious challenges. The extensive use of chemical fertilizers not only greatly increases the cost and causes a lot of waste, but more seriously pollutes the soil a...

Its advantage is that it saves labor, can effectively prevent grass shortage and protect the soil structure; the disadvantage is that it increases the cost and pollutes the soil to a certain extent.

[0009] However, before planting, no gardening and land preparation and soil fertility have been carried out. After the fruit seedlings are planted, the plowing layer is shallow, the structure is poor, the fertility is low, the organic matter is low, and the pH is not suitable, which has brought great troubles to the planting.
