Planting method of high-quality selenium-enriched tea

Abstract

The invention discloses a planting method of high-quality selenium-enriched tea. The planting method comprises the following steps: selecting a planting land, and constructing horizontal terraced fields on the planting land; spreading a first matrix fertilizer on the surface of the terraced fields, performing overturning and crushing on the terraced fields, and after the overturning and crushing are completed, airing the terraced fields; after the airing is completed, spreading a second matrix fertilizer on the surface of the terraced fields, performing overturning and crushing on the terracedfields, and after the overturning and crushing are completed, airing the terraced fields; after the airing is completed, flatting the surface of the terraced fields, and inserting tea seedlings on the flattened terraced fields; after tea seedling cutting is completed, performing watering on the terraced fields; performing shallow ploughing and weed removing 3-4 times every year during the non-picking season; performing irrigation according to the degree of drought in the dry season, and performing proper drainage in the rainy season; after the tea seedlings are planted, applying a selenium-enriched fertilizer on the 10th day, and applying the selenium-enriched fertilizer every two months thereafter; and when young leaves of tea trees grow to a picking standard, performing picking on the tea trees. The planting method can improve the selenium content of the tea, thereby improving the quality of the selenium-enriched tea.

Description

technical field [0001] The invention relates to the technical field of tea planting, in particular to a planting method of high-quality selenium-enriched tea. Background technique [0002] Tea is a famous health drink. The drinking of tea by the Han people began in Shennong for more than 4,700 years. Until now, Chinese Han compatriots still have the custom of serving tea instead of courtesy. Tea belongs to the family Theaceae, and is an evergreen shrub or small tree plant. Tea trees like a humid climate and are widely cultivated in the south of the Yangtze River Basin in China. The leaves of the tea tree are made into tea leaves, which are soaked in water and used. The leaves of the tea tree can be picked after 3 years of planting. Generally, the tender buds with 4-5 leaves are picked around Qingming, and the quality of the tea leaves is very good, which is a treasure. Tea, cocoa, and coffee are called the world's three major non-alcoholic beverages. [0003] Tea is kn...
