Strengthen the awareness of resource protection, scientifically manage and protect ancient tea trees
China Flower and Tree Garden News Reporter Bai Bin Li Zhixian Wang Jun reported that the ancient tea trees in Menghai County, Yunnan Province, are not only valuable resources, but also with the optimism of the Pu'er tea market, they have also created huge economic benefits for local county tea farmers. However, with the destruction of the ecological environment and the lack of management technology, the diseases and insect pests of ancient tea trees have become increasingly serious. Therefore, it is imperative to improve the awareness of tea farmers on the protection of ancient tea tree resources and scientifically manage and protect ancient tea trees.
According to Chen Jianfeng, director of the Menghai County Tea Technical Service Center, at present, common diseases and pests in ancient tea gardens in Menghai County include thrips, small green leafhoppers, tea long white borers, tea valley moths and so on. Chen Jianfeng pointed to the white spots on a tea tree and introduced: This is a tea long white beetle, and the bulge on the branch is the symptom after its harm. Affected by its harm, not only will the tea branches die, but also affect the entire tea garden after spreading.
Chen Jianfeng told reporters that although the moss and lichen parasitic on the branches are beautiful, the harm to tea trees is also serious. Mosses and lichens are like blood-sucking insects, which will absorb the nutrients of tea plants, causing tea plants to grow weakly and even die of branches. Therefore, it is necessary to completely remove the moss and lichen attached to the tea tree to ensure the healthy growth of the tea tree.
According to Chen Jianfeng, soil cultivation management is an important part of tea garden management, and scientific management methods are particularly important, but soil farming is generally ignored in tea garden management. To this end, Chen Jianfeng pointed out that every winter to carry out a ploughing of the soil, the purpose is to increase the soil permeability and air permeability, promote the regeneration of the root system, enhance the absorption capacity of nutrients, followed by deep soil turning, reduce the occurrence of diseases and insect pests, and then help the soil to absorb water more easily during the rainy season. "Soil tillage is recommended to be implemented in relatively gentle tea gardens, and for some steep slopes, or tea gardens with loose soil, tillage is not recommended." Chen Jianfeng said.
Chen Jianfeng stressed that the trees in the tea garden can not only play a role in maintaining the water and soil of the tea garden, but also provide shade for the tea plants, improve the microclimate of the tea garden, and increase the humidity in the tea garden, which can improve the quality of tea. In addition, the trees in the tea garden can also provide a habitat for birds and other natural enemies of tea tree pests, thereby reducing the occurrence of insect pests, so it is necessary to guide the majority of tea farmers to take good care of the trees in the tea garden, and at the same time, the relevant departments will increase the investigation and punishment of deforestation to ensure the ecological environment of the ancient tea garden.
