Embodiment 1

[0025] The invention provides a method for soil improvement of tea plantation, specifically comprising the following steps:

[0026] Step 1: tea tree clearing treatment: pull out the tea trees on the tea planting ground, and remove the dead branches and fallen leaves on the tea planting ground, dry them in the sun, and collect them for later use;

[0027] Step 2: Soil deep plowing treatment: After cleaning the tea trees and dead branches and leaves in the tea garden, plow the soil of the tea plantation site 30-40cm deep, and break up the deep plowed soil. At the same time, remove the deep plowed soil Grass roots, tree roots and stones dug up during the process;

[0028] Step 3: Soil multi-stage sterilization treatment:

[0029] (1) First-level disinfection: Spread the crushed soil and expose it to the hot sun. When the sunlight weakens, knead the spread soil into a pile, pour water and cover it with plastic film for stewing shed treatment, and so on. 8-10 days;

[0030] (2)...

Abstract

The invention discloses a soil improvement method for tea planting, specifically relates to the technical field of soil improvement, and specifically comprises the following operation steps: tea tree clearing treatment→soil deep plowing treatment→soil multi-stage sterilization treatment→soil modification treatment→adding organic Fat. Sterilize the soil of the tea plantation land for many years by adopting the composite sterilization method of sun sterilization + stewed shed sterilization + incineration sterilization + chemical sterilization, and at the same time, use dolomite powder to increase the pH value of the tea plantation soil, and Increase the cation exchange capacity of the soil, use Robinia locust leaves to reduce the amount of exchangeable acid and exchangeable aluminum in the soil, further increase the content of soil exchangeable calcium and magnesium, thereby inhibiting soil acidification, and use physiological alkaline fertilizers to prevent The continuous decrease of the pH value of the soil for tea planting makes the pH value of the soil rise back to the range suitable for tea planting, and the effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of soil improvement, and more specifically, the invention relates to a method for improving soil for tea plantation. Background technique [0002] Tea trees are perennial dryland crops. After many years of planting tea trees in the same land, the soil properties of this land are no longer suitable for planting tea trees. If you continue to plant tea trees, the yield will become lower and the fertilizer required will be greatly reduced. The increase is mainly due to the increase in the content of harmful fungi and insects in the soil, and at the same time, the pH value of the soil has also dropped seriously. Therefore, if you want to continue to use this land to grow tea, you must improve the properties of the soil. [0003] However, when the improvement method in the prior art is used to improve the soil, there are still many shortcomings, such as a low degree of improvement in the content of harmful bacteri...
