Construction method of biodiversity tea garden

Abstract

The invention provides a construction method of a biodiversity tea garden. According to the construction method, Chinese birches are planted in the tea garden and arbor-type tea trees are grown in the tea garden to achieve a shading effect in the tea garden; green manure crops such as fungi, beans and white radish are interplanted in the tea garden to increase the soil fertility; meanwhile, diseases, insect pests and weeds in the tea garden are controlled by use of agricultural and biological measures. As a result, a stereoscopic ecological community structure, namely Chinese birch shading trees at the upper layer, arbor-type old tea trees at the middle layer, ecological tea garden at the lower layer and weed green manure at the bottom layer, is formed in the tea garden, and a compound ecological tea garden system which is reasonable in structure and stable in function is constructed. The problems of excessive pesticide residue, declining of biodiversity, harm to tea food safety and the like due to the application of pesticides and chemical fertilizers in the tea garden are solved. The yield of the tea garden is increased, the tea quality is guaranteed and the tea quality reaches the organic level.

Description

technical field [0001] The invention relates to a method for constructing a biodiversity tea garden. Background technique [0002] At present, the tea planting model in most tea areas in my country is a "single tea" model, that is, the entire land is reclaimed for tea plantation, and the tea tree variety is single, which not only reduces the effective use of land, but tea trees are perennial evergreen crops. The phase climate is more stable than that of ordinary farmland. In the tea garden, the tea tree is the only dependent of the insect community, so the stability of the insect community is poor. Moreover, the ecological environment of the entire tea area and the physiological functions of tea trees are prone to imbalance, poor nutrient circulation, soil fertility decline, and the ability of tea gardens to resist diseases and insect pests are reduced, resulting in reduced tea inclusions, reduced tea yield, and lower quality. A large amount of chemical fertilizers and pest...

AI Technical Summary

Problems solved by technology

In the tea garden, the tea tree is the only dependent of the insect community, so the stability of the insect community is poor

Moreover, the ecological environment of the entire tea area and the physiological functions of tea trees are prone to imbalance, poor nutrient cycle, soil fertility decline, and tea plantation resistance to diseases and insect pests are reduced, resulting in reduced tea inclusions, reduced tea yield, and lower quality

A large amount of chemical fertilizers and pesticides are required, which may lead to excessive pesticide residues in tea and endanger the food safety of tea
