Soil improvement method of ecological tea garden

Abstract

The invention discloses a soil improvement method of an ecological tea garden and relates to the technical field of ecological tea garden establishment. The soil improvement method is characterized by including the steps of 1), land selection; 2), land regulation; 3), planting of leguminous green manure; 4), application of weathering coal; 5), application of organic fertilizer containing rhizobium; 6), adjustment of soil aid and alkali in the tea garden. The soil improvement method has the advantages that soil is well improved via placement and cultivation application of the weathering coal and planting of the leguminous green manure, the soil is fertile, fertility is long and stable, the soil is loosen, construction of the standardized ecological tea garden and development of tea industry are benefited, and higher market demand is met.

Description

Technical field: [0001] The invention relates to the technical field of ecological tea garden construction, in particular to a soil improvement method for an ecological tea garden. Background technique: [0002] Anhui Province is located in the middle and lower reaches of the Yangtze River. It has a mild and humid climate and four distinct seasons. The area of ​​mountains and hills accounts for more than 60% of the province. Especially the Huangshan Mountain in the south and the Dabie Mountain in the southwest are suitable for tea plantation. They are the main production and processing places for tea in our province. In the mid-1970s, the planting area of ​​tea gardens in our province was basically at the forefront of the country, reaching more than 1 million mu. In the 1990s, it accounted for 11.2% of the national tea garden area, reaching 1.78 million mu, second only to Zhejiang and Yunnan, ranking third in the country. , but after the 1990s, due to various reasons, the ar...

Problems solved by technology

In the mid-1970s, the planting area of ​​tea gardens in our province was basically at the forefront of the country, reaching more than 1 million mu. In the 1990s, it accounted for 11.2% of the national tea garden area, reaching 1.78 million mu, second only to Zhejiang and Yunnan, ranking third in the country. , but after the 1990s, due to various reasons, the area of ​​tea gardens grew slowly and fluctuated, and its proportion in the country declined year by year, and its ranking fell. In recent years, it is far lower than the two major tea-growing provinces of Guizhou and Yunnan. The province does not pay enough attention to the development of tea production, and the investment in infrastructure construction is not large. Compared with other major tea-producing provinces, the construction and development of tea gardens lag behind

[0004] Nowadays, chemical fertilizers and pesticides are more or less used in the construction of ecological or organic tea gardens, or farmyard manure is used directly. The invention patent of patent CN201610047271.1 discloses a method for improving the soil ecology of tea gardens. This technology interplants beans in tea gardens. In the process of plant clover, use rhizobia to directly dress seeds, and use inorganic fertilizers to promote strong seedlings and increase grass yield. Direct seed dressing may not really play the role of inoculating rhizobia, and it uses inorganic fertilizers as topdressing It is said that the construction of ecological tea gardens is not allowed
