Healthy and ecological planting method of organic selenium-enriched white tea

Abstract

The invention relates to a healthy and ecological planting method of organic selenium-enriched white tea. The method includes the steps of firstly, digging planting furrows 15cm in depth and 30cm in width in a tea garden, laying mulches in the planting furrows, laying a mixture layer formed by rice husks 5cm in thickness and humus on the mulches, laying organic selenium fertilizer mixture 2cm in thickness on the mixture layer, and covering the organic selenium fertilizer mixture with 8cm of soil; secondly, transplanting white tea trees into the planting furrows according to standardized specifications of tea trees, sufficiently watering the white tea trees after the transplanting, and covering the ground with a layer of straw; thirdly, timely supplementing the organic selenium fertilizer mixture in spring and autumn in the first year of transplanting; fourthly, performing standardized tea garden management, to be more specific, mainly paying attention to the maintenance of the planting furrows, watering in dry summer, timely weeding in spring, mainly performing topdressing, weeding and furrow cleaning in autumn and preventing freezing damage in winter; picking tea leaves in the vigorous growing period of the selenium-enriched white tea instead of early spring after 2-3 years of cultivation.

Description

technical field [0001] The invention relates to the technical field of organic tea planting, in particular to a healthy and ecological planting method of organic selenium-enriched white tea. 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...

AI Technical Summary

Problems solved by technology

However, due to the use of soil root application in the middle stage of crop growth, it is impossible to ensure that the nutrients are fully absorbed by the tea trees.

Most of the selenium in the nutrient will remain in the soil, and will be lost with rainwater or irrigation water, which will increase the burden of selenium in the soil and water environment. Long-term use will easily lead to selenium pollution

However, the relevant known technologies do not involve selenium-enriched tea seedlings, tea leaves rich in organic selenium, and specific production methods for cultivating tea leaves rich in organic selenium.
