Paddy field soil amendment

Abstract

The invention provides paddy field soil amendment and relates to the technical field of soil improvement. The Paddy field soil amendment is made of, by weight, 25 parts of silicate, 6 parts of alums, 10-20 parts of bacillus subtilis powder, 15 parts of fulvic acid, 10 parts of chlorogenic acid, 15 parts of straw decomposition additives, 8 parts of yellow sand, 8 parts of composting soil, 8 parts of bamboo and wood ash, 8 parts of azotobacter powder, 55 parts of bog rotten straw fertilizer, 35 parts of grain slag fertilizer, 15 parts of diatom ooze and 25 parts of fine silica powder. The paddy field soil amendment has the advantages that raw materials adopted for the paddy field soil amendment are rich and low in price, the preparation technology is simple, the prepared paddy field soil amendment is suitable for improving paddy field soil, the improved paddy field soil has good fertilizer maintaining and moisture maintaining effects, the fertilizer effect is relieved in soil slowly, and it can be avoided that a great amount of nutrient elements required by plants in the soil are lost in the watering and irrigating processes.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to an amendment for improving paddy field soil and a preparation method thereof. Background technique [0002] Cultivated land is the basic resource and condition for human survival. Entering the 21st century, the population is increasing, the cultivated land is gradually decreasing, and people's living standards are constantly improving. To maintain sustainable agricultural development, we must first ensure the quantity and quality of cultivated land. According to incomplete statistics from the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the Food and Agriculture Organization (FAO), the land area of ​​the world is about 1.829 billion hectares, and the per capita arable land is 0.26 hectares. As of December 31, 2011, the amount of cultivated land in the country was 1.82476 billion mu. Basic farmland refers to the cultivated land that canno...

Problems solved by technology

Because basic farmland is the essence of cultivated land, strengthening the protection of basic farmland and implementing special protection for high-quality cultivated land has played a positive role in ensuring national food security. , are diverse, so the damage to the current soil is relatively large. The soil contains a lot of chemical substances, but it is becoming more and more barren, and the fertility is getting weaker. Planting crops requires the application of a large amount of chemical fertilizers to ensure the harvest. When the soil is actually planted, it has a great impact on the crops, especially for the paddy fields at the current stage. The loss of soil nutrients is serious, and the ability to retain fertilizer is poor. After adding new water to the paddy fields, the fertility will decline. Nutrient elements in the paddy fields cannot meet the needs of rice growth
