Tea garden moisture conservation tillage minimizing method

Abstract

The invention belongs to the tea plant cultivation technical field, and specifically relates to a tea garden moisture conservation tillage minimizing method comprising the following steps: deep tillage impurity removing and base fertilizer reapplying are done before the tea garden is closed in September-October; uniformly broadcasting trifolium repens seeds in blank zones between lines in the tea garden according to a ratio of 1.0-1.5Kg / mu; raking seeds and capping soil in the surface; doing earthing work with the earthing depth of 0.5-1.0cm; keeping surface soil to be moisture after the earthing work; re-applying nitrogenous fertilizer for one time according to a ratio of 10kg / mu before rhizobium is not generated in a 30-50days period of the trifolium repens seedling stage. The method can utilize competition and allelopathy effects between plants so as to improve tea garden ecology, thus improving soil quality, reducing weed survival space, finally realizing less-tillage or even non-tillage effect of the tea garden cultivation management, and providing important meanings for tea sustainable production and simplification works.

Description

technical field [0001] The invention belongs to the technical field of tea tree cultivation, and in particular relates to a method for preserving moisture and reducing tillage in tea gardens. Background technique [0002] Cultivation is an important technical link in the cultivation and management of tea gardens. Its purpose is simply to maintain soil moisture and hoe weeds in tea gardens. Among them, water conservation in tea gardens is mainly achieved by reducing soil water loss and expanding soil water storage capacity. Common moisture conservation measures include laying grass between rows, plastic film mulching, and hoeing to conserve water. However, mulching with plastic film will have a negative impact on the permeability of tea garden soil. Part of the water will be blocked by the plastic film and difficult to enter the soil plow layer. Moreover, the plastic film itself will cause secondary pollution to the tea garden soil. At the same time, due to the complex terra...

Problems solved by technology

Manual weeding in tea gardens is labor-intensive and labor-intensive, and the duration of no weed damage is short (only 10-20 days), and the benefit of weed control is low

The cost of chemical weeding is relatively low, and the effect of weed control is relatively good. However, the use of herbicides in tea gardens pollutes tea leaves, resulting in excessive pesticide residues in tea leaves. At the same time, continuous use of herbicide residues in the soil will also destroy microorganisms and soil insects in the soil. And the community structure of other small animals will also cause great harm to the normal structure of the tea garden soil rhizosphere biodiversity
