Black tea planting method

Abstract

The invention discloses a black tea planting method, and relates to a planting method of tea. The method mainly comprises five steps of 1, preparing organic selenium fertilizer; 2, applying the fertilizer; 3, planting grass; 4, turning soil; 5, picking. According to the main process, the fertilizer is applied from the middle ten days of September to the first ten days of October, with a tea tree distance being 30 cm, a shallow trench with the depth of 10 cm is dug, and the fermented organic selenium fertilizer is evenly drilled among rows; then alfalfa seeds are sown on the organic fertilizer, and straw or weeds are covered with thin 2-3 cm of thin soil; in the first 5-10 days before spring tea sprouts, the alfalfa is shoveled away, the alfalfa is covered with 10-15 cm of soil, and then the tea is picked 15-20 days after the spring tea sprouts. Since the alfalfa is a selenium aggregation plant, loss of selenium element in the soil can be reduced, but after the alfalfa is shoveled away and covered with the soil, the alfalfa forms the organic fertilizer to increase the content of the selenium element in the soil, and thus the balance of the selenium element in the soil is maintained.

Description

technical field [0001] The invention relates to a tea planting method, in particular to a black tea planting method. Background technique [0002] China is the hometown of tea and the ancient country of tea. The discovery and utilization of tea trees has a history of more than 10,000 years. It is the birthplace of human beings drinking tea, growing tea and making tea. Tea has become the most vital and popular civilized and healthy beverage among the three major beverages in the world. With the improvement of people's living standards, the enhancement of health awareness and the rise of tea culture, people's demand for tea quantity and quality is gradually increasing and improve. [0003] Selenium, the element symbol Se, is an essential trace element for the human body. It has biological properties such as anti-cancer, anti-aging (anti-oxidation), improving human immunity, and antagonizing heavy metals. Selenium in the food chain mainly comes from soil. The distribution of...

Problems solved by technology

Although selenium-enriched tea can be obtained by this planting method, due to the limited ability of tea to absorb selenium, after applying organic selenium fertilizers to the soil, a large amount of selenium will be taken away by the erosion of the soil by rainwater, resulting in The loss of selenium element; the loss of selenium element in the soil will directly affect the content of selenium element in tea, resulting in the waste of organic selenium fertilizer

In addition, there is an interval of several months between fertilization and picking, but the growth of tea buds only takes 15-20 days. After fertilization, the selenium content in the soil will gradually decrease as the rain washes away the soil. When picking, the growth of young shoots will not be able to get enough selenium supplement, so it will also affect the selenium content in tea.
