Problems solved by technology

However, a large number of studies have shown that soil acidification in tea gardens will not only destroy the soil microbial flora, but also affect the mineralization of soil organic matter and the cycle transformation of nutrients, hinder the absorption of nutrients by tea trees, which is not conducive to the growth of tea trees, and is one of the important factors affecting the bioavailability of soil selenium

Abstract

The invention relates to the technical field of tea gardens, and discloses a fertilizing method for a tea garden with strong acid soil, which comprises the following steps: 1, preparing soil and bedding; 2, preparing a test material; 3, primary fertilization; and 4, secondary fertilization. According to the method disclosed by the invention, an alkaline modifier is firstly applied to neutralize the acidity of soil in a staggered combined application manner, so that the chemical effectiveness of selenium in the soil is improved; meanwhile, the influence of low pH of soil and an alkaline modifier on the bio-organic fertilizer is relieved, so that the bio-organic fertilizer can better adapt to the soil environment of the tea garden; after the bio-organic fertilizer is applied, the microbial community structure of the rhizosphere soil of the tea tree is improved, selenium in the soil is further activated, the root growth of the tea tree is promoted, and the capability of the tea tree for absorbing nutrient elements such as selenium is improved, so that the bio-availability of the selenium in the soil of the strong-acidity high-selenium tea garden is improved.

Description

technical field [0001] The invention relates to the technical field of tea gardens, in particular to a fertilization method for tea gardens in strongly acidic soil. Background technique [0002] Selenium (Se) is known by scientists as the "king of anti-cancer" among trace elements in the human body. A large number of studies have shown that the occurrence of many diseases is related to the low intake of selenium, appropriate supplementation can improve the body's resistance to certain diseases, and can also prevent diabetes, cardiovascular and cerebrovascular diseases, Keshan disease, Kashin-Beck disease, etc. . The sources of selenium supplementation mainly include inorganic selenium and organic selenium. Among them, organic selenium from biological sources is the most safe, less prone to selenium poisoning, easy to be absorbed by the human body, and has high selenium supplementation efficiency, so it is the most popular. The acquisition of bio-sourced organic selenium is...
