Description
Technical Field
The invention belongs to the technical field of soil improvement, and particularly relates to a tea acidified soil restoration bio-organic fertilizer and a preparation method thereof.
Background
At present: tea trees are typical acid-loving crops, and the suitable pH value of the tea trees is 4.5-5.5. After the tea trees are planted, the soil can be gradually acidified due to physiological effects of organic acid secretion and the like of the tea trees; acid rain, excessive application of fertilizers, particularly urea and ammonium nitrogen fertilizers, can aggravate soil acidification. The research shows that the tea garden soil is continuously acidified, according to the research of tea institute of Chinese academy of agricultural sciences, the pH value of most tea garden soil in the three provinces of Jiang, Zhe and Wan in 1990 and 1991 is above 4.5, the pH value is only 13.7% when the pH value is less than 4.0, the measurement result in 1998 is increased to 43.9%, and the recent research shows that the pH value of nearly half of tea garden soil is less than 4.0. On the national scale, tea garden soil also shows a continuous acidification trend, and at present, the pH value of the soil is less than 4.0 by about one third.
Tea trees are acid-loving crops, the pH value of soil is more than 6.5, the growth and development of the tea trees are not facilitated, but the excessive acidification causes serious imbalance of soil nutrients, poor biological properties and soil hardening, and the growth and development of the tea trees are also influenced. If the pH value of the soil is about 5.0, the tea tree has developed root system and vigorous growth, tea buds are strong, and young shoots grow quickly; when the pH value is less than 4.0, the root tip is atrophied and growth is inhibited, at the moment, the absorption of nitrogen, phosphorus and potassium by the tea tree is sharply reduced, germination is retarded, and young shoots grow slowly. In addition, excessive acidification can also lead to the improvement of the bioavailability of heavy metal elements such as lead in the soil, thereby affecting the safety quality and the quality of the tea. Therefore, the method for improving the severely acidified tea garden soil not only can obviously improve the soil quality level, but also has an important effect on improving the tea yield and quality.
At present, lime substances are generally used for improving acidified soil in agricultural production, the problem of soil acidification cannot be fundamentally solved by applying lime, and certain adverse effects exist, such as: reduce the water permeability of soil, slow down the growth of leguminous and non-leguminous crops, reduce the phosphorus absorption of plants and the like. The nitrogenous fertilizer in the chemical fertilizer market of China mainly contains urea and ammonium nitrogen, the phosphatic fertilizer market mainly contains monoammonium phosphate, diammonium phosphate and calcium superphosphate, and the potash fertilizer mainly contains potassium sulfate and potassium chloride.
Through the above analysis, the problems and defects of the prior art are as follows: the existing acidified soil improvement can not solve the problem of soil acidification, and can affect the yield and quality of tea leaves.
