Method for improving soil fertility of mountain tea garden

Abstract

The invention discloses a method for improving the soil fertility of a mountain tea garden. The method comprises tea garden soil improvement and balanced fertilization; the tea garden soil improvement comprises performing intermittent cultivation on the tea garden, wherein the intermittent cultivation comprises performing cultivation once in the spring tea additional fertilizer period, the summer tea additional fertilizer period and the autumn base fertilizer period of the cultivation year, planting ryegrass between rows of the tea garden after the last cultivation in the cultivation year and mowing and digging the ryegrass in the soil in the following June; the balanced fertilization comprises applying 29.5 to 30.5 kg fertilizer for tea to every mu of tea in the spring tea additional fertilizer period and the summer tea additional fertilizer period and applying 39.5 to 40.5 kg fertilizer for tea and 24.5 to 25.5 kg plant protein organic fertilizer to every mu of tea in the autumn base fertilizer period. According to the method for improving the soil fertility of the mountain tea garden, the soil fertility conditions of the soil of the mountain tea garden can be effectively improved.

Description

technical field [0001] The invention relates to the field of tea planting, in particular to a method for improving soil fertility of tea gardens in mountainous areas. Background technique [0002] Tea is an important economic crop in my country, and its development has a profound impact on the economic revitalization of tea areas, market supply and the establishment of famous tea brands. However, the basic national conditions of insufficient land resources in our country determine that the site conditions of the tea industry are generally poor, and most of them are mountainous areas, especially in Anhui Province, which is one of the main tea producing areas in China. According to survey statistics, about 70% to 80% of tea gardens in Anhui Province are distributed in mountainous areas. [0003] Mountain tea gardens have poor soil, thin soil layer, and poor water and fertilizer retention capacity. In order to achieve high yields, farmers in tea areas generally use excessive ...

Problems solved by technology

This empirical production method of tea farmers not only makes it difficult to continuously improve the yield and quality of tea, but also causes waste of resources and increases the risk of ecological environment pollution

In addition, no-tillage is the main method of soil cultivation in mountainous tea gardens in my country. Although this farming method can maintain the soil structure, since tea trees are perennial crops, years of no-tillage tend to lead to the lack of organic matter in the soil, soil compaction, and reduced soil porosity. , poor permeability, overgrown weeds, and reduced nutrient supply capacity of the soil, resulting in early decline in tree vigor and yield, and decline in tea quality

Moreover, no-tillage leaves the surface exposed for a long time, increasing the risk of soil erosion, which is especially serious in mountainous tea gardens

It can be seen that the traditional tea farmers' production methods and soil cultivation systems will affect the improvement of soil quality.
