A kind of selenium-enriched high-quality rattan tea planting method

Abstract

The invention provides a selenium-enriched and high-quality rattan tea planting method. The specific steps are as follows: geographical environment selection, seedling preparation, planting condition establishment, seedling planting, trench backfilling, and distributed fertilization. The selenium-enriched high-quality rattan tea planting method is reasonably designed. , The application of selenium fertilizer is carried out by means of distributed fertilization. The fertilization device can intermittently apply selenium fertilizer and other fertilizers to the soil gap by inserting the tip into the steel pipe. When fertilizing, the air-borne powder fertilizer is used. The mixed fertilizer enters the various gaps in the soil through the fertilizer release holes on the steel pipe with the tip inserted, thereby improving the distribution range of the fertilizer in the soil. The fertilizer is distributed in the soil around the seedlings, making the fertilizer more easily absorbed by the seedlings. It can improve the survival rate of seedlings in the early stage of planting, prevent the accumulation of fertilizers, which is not easy to be absorbed and damage the root system of seedlings, and the good absorption of selenium fertilizer is beneficial to the increase of dihydromyricetin content in vine tea general leaves.

Description

technical field [0001] The invention belongs to the technical field of rattan tea planting, and particularly relates to a selenium-enriched high-quality rattan tea planting method. Background technique [0002] Selenium in the earth's crust is the original source of selenium in the natural environment. Rock, soil, water, and atmosphere all contain a certain amount of selenium. The selenium in the soil comes from the parent rock. Oxides are washed into the soil by rain, volcanic movements, industrial waste gas emissions and other human activities make selenium enter the atmosphere and water, and the selenium entering the environment undergoes biotransformation and transfer process, forming a natural selenium cycle ecological chain, soil selenium It is the direct source of plant selenium. Selenium is absorbed by plants in the form of selenate, selenite or organic selenium. The roots and leaves of plants have certain absorption capacity. When selenium fertilizer is applied, roo...

[0002] Selenium in the earth's crust is the original source of selenium in the natural environment. Rocks, soil, water, and the atmosphere all contain a certain amount of selenium. Oxides, washed into the soil by rain, volcanic movement, industrial waste gas emissions and other human activities, make selenium enter the atmosphere and water, and the selenium entering the environment undergoes biotransformation and transfer processes to form a selenium cycle ecological chain in nature. Soil selenium It is the direct source of selenium in plants. Selenium is absorbed by plants in the form of selenate, selenite or organic selenium. Plant roots and leaves have a certain absorption capacity. When selenium fertilizer is applied, root fertilization and leaf selenium are generally used. The method of surface spraying, foliar spraying has certain risks, especially for the planting of vine tea, which often has fewer leaves and weak absorption capacity, and root fertilization is required. However, the existing vine tea planting method is When fertilizing, the fertilizer is often piled directly on the base of the vine tea. After the roots of the vine tea seedlings develop, if they extend to the place where the fertilizer gathers, it is very easy to damage the root system, thereby reducing the survival rate of the vine tea, which is not conducive to the normal growth of the vine tea. For this reason, the present invention proposes a kind of selenium-enriched high-quality vine tea planting method
