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...

AI Technical Summary

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
