Problems solved by technology

The amount of fertilizer used in tea gardens is large, and more physiologically acidic fertilizers are used. The acidification of tea garden soil is more prominent than that of ordinary cultivated land. sustainable development
[0003] The traditional method of improving acidic soil is to use lime or limestone powder alone. Applying lime can obviously reduce the acidity of acidic soil, but sometimes it will increase the degree of reacidification
There are also some acidic soil compound improvers on the market, the main component is a mixture of lime and some minerals or industrial by-products, but most of these improvers contain a certain amount of toxic metal elements, such as lead, cadmium, arsenic, chromium, etc. , there is a problem of pollution to the soil environment

Embodiment approach

[0010] As a kind of embodiment of the present invention, a kind of tea garden soil improvement method comprises the following steps:

[0011] The first step is to plow and loosen the soil of the tea garden, and then sprinkle the soil improver on the soil. The soil improver is prepared by the following method: step 1, prepare calcium carbonate powder, and grind the calcium carbonate to a thickness of 80 mesh ; Step 2, preparing chicken manure / pig manure granules, fermenting and maturing chicken manure / pig manure at 40 degrees Celsius for 20 days, then drying it to a water content of 3.5-4%, and then granulating the chicken manure / pig manure The manure granules are dried until the water content is lower than 2%; step 3, mix calcium carbonate powder and chicken manure / pig manure granules together, then add 100 mesh charcoal powder, yeast, Bacillus subtilis, potassium fulvic acid, and mix the above The components are mixed and stirred evenly at normal temperature to obtain the tea...

Abstract

The invention provides a tea garden soil improvement method, and relates to the technical field of soil improvement. The tea garden soil improvement method comprises the steps of (1) shallow-ploughing and loosening tea garden soil, and spraying a soil conditioner on the soil; (2) deep-ploughing the tea garden soil, and turning over and burying the soil conditioner into the soil; and (3) applying organic composite fertilizer on the soil surface and covering up by shallow soil. The method has a few steps, and is easy to operate, materials of the soil conditioner are simple and easily obtained, manufacturing cost is low, and the tea garden soil is prevented from being polluted.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a tea garden soil improvement method. Background technique [0002] At present, most of the tea gardens in southern my country that have been planted for more than 5 years have a certain degree of soil acidification. Soil acidification is a manifestation of soil degradation, which refers to a natural phenomenon in which soil acidification increases and becomes strongly or extremely acidic. Phenomenon. Soil acidification in my country is becoming more and more serious. The acidified land area has expanded to more than 40% of the cultivated land area in my country, and it often occurs in large areas, especially in the south of my country. Because the soil itself is acidic and there is much rain, the soil The phenomenon of acidification is even more serious, with more than 70% of the soil acidified or severely acidified in Hunan. The amount of fertilizer used in tea gardens...
