Improvement preparation for improving soil of dry farmland

Abstract

The invention discloses an improvement preparation for improving soil in a dry farmland and relates to the technical field of preparation of a soil improvement agent. The improvement preparation is prepared from the following raw materials in parts by weight: 40 parts of nitrogenous fertilizer, 15 parts of phosphate fertilizer, 12 parts of potash fertilizer, 8 parts of nitrogen-fixing bacteria powder, 6 parts of fulvic acid, 4 parts of aminosalicylic acid, 55 parts of bog rotten straw fertilizer, 35 parts of grain slag fertilizer and 36 parts of silicon dioxide micropowder. The raw materials of the preparation are rich and cheap; a preparation technology is simple and convenient; biomass is selected more safely; the preparation meets metabolism of microorganisms in the dry land, is suitable for the relatively barren farmland, has a better effect of supplementing fertility to the soil, and is obvious in use effect; the soil has a better fertilizer maintenance effect by the action of the silicon dioxide micropowder; and loss of nutritive elements in the soil is avoided.

Description

technical field [0001] The invention relates to the technical field of soil improver preparation, in particular to an improvement preparation for improving upland 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 cultivat...

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, and there are still a large amount of chemical substances in the soil. This kind of soil has a great impact on the actual planting of crops, which will cause slow growth of crops and poor disease resistance.

[0003] At present, a major problem still exists in most of the cultivated land in my country is that the soil fertilizer retention capacity is poor, and the nutrients required for crop growth are lost quickly, and a large amount of topdressing chemical fertilizers are needed to meet the nutrients required for crop growth.
