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,

Embodiment

[0030] Experimental location: Bazhuang base tea garden of Songluo Organic Tea Development Co., Ltd.

[0031] Current status of the tea garden: yellow-red soil developed from phyllite and sand shale, with a pH of around 4.51. The tea tree varieties are local group species, and the tea trees are double planted and densely planted. The annual application of pure nitrogen is about 20kg per mu, the level of fertilization is medium, and the yield is low.

[0032] Treatment method: adopt this method from 2012 to 2013, and set up a test area (indicated by T in the table) in the tea garden, with an area of ​​1000m 2 . 1 control area (indicated by CK in the table), with an area of ​​1000m 2 .

[0033] The seeds are sown on the blank strip between the rows of the tea garden, and the surface seeds and floating soil are evenly raked with a shallow-toothed nail rake, and the soil covering operation is carried out. The covering depth: 0.5-1.0cm, and the seed dosage: 1.0-1.5kg / mu. Grass ...

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...
