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 tea planting soil improvement method, and particularly relates to the technical field of soil improvement. The method specifically comprises the following operation steps of tea tree garden cleaning treatment, soil deep ploughing treatment, soil multistage sterilization treatment, soil modification treatment and organic fertilizer application. According to the method, the soil of tea planting land for many years is sterilized in a composite sterilization manner of sun sterilization, shed braising sterilization, incineration sterilization and chemical sterilization, meanwhile, dolomite powder is used for improving the pH value of the tea planting soil, the cation exchange capacity of the soil is increased, and the quantity of exchangeable acid and exchangeable aluminum in the soil is reduced through robinia pseudoacacia leaves; and the content of exchangeable calcium and magnesium in the soil is further increased, so that soil acidification is inhibited, the pH value of the tea planting soil can be prevented from being continuously reduced by utilizing physiological alkaline fertilizer, the pH value of the soil is increased to a range suitable for planting tea, and the action 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...
