Raw material composition and preparation method of sustained-release drought-resistant water-retention nutrient

Abstract

The invention relates to a raw material composition and preparation method of a sustained-release drought-resistant water-retention nutrient. The drought-resistant water-retention nutrient provided by the invention is prepared from the following raw materials in parts by weight: 550-700 parts of HA35% ammonium phytate, 80-200 parts of N64% coated urea, 60-150 parts of P14 phosphate fertilizer, 60-150 parts of N17 and P44 ammonium phosphate, 20-35 parts of chitin, 3-30 parts of 80-mesh kushenin and 20-50 parts of glauconite. The sustained-release drought-resistant water-retention nutrient prepared by the preparation method provided by the invention has the characteristics of synchronous plant absorption and sustained release, high water absorption capability, good stress resistance and water retention properties, entire nutrients, rich bioactive substances and soil activation, can improve leaf photosynthesis, prevent bacteria infection and alleviate drought-induced plant physiological damage, has significant effects in greenness, environment friendliness and quality and efficiency improvement, is especially suitable for production of food economical crops, and has persistency and controllability on the drought resistance and nutrient supply.

Description

1. Technical field: [0001] The invention relates to a raw material composition and a preparation method of a slow-release drought-resistant and water-retaining nutrient. 2. Background technology: [0002] my country is a large agricultural country with vast territory and rich resources. However, serious natural disasters are extremely unfavorable to the sustainable development of agriculture. Agricultural production is facing severe challenges. Drought has become the most common natural disaster that people face. At present, arid areas account for 41% of the world's land area. my country is an arid area. Larger countries, especially the 16 northern provinces, have arable land area of ​​51.3 million hectares, accounting for 51% of the country's arable land area. Among them, the loess dryland area in the northwest is a typical semi-arid area. Due to the low rainfall and uneven temporal and spatial distribution, crops need to The "misalignment" of water quantity and water suppl...

AI Technical Summary

Problems solved by technology

In recent years, many drought-resistant nutritional fertilizers have appeared at home and abroad in response to the lack of water and poor nutrients in dry-farmed areas. However, similar foreign products do not match the conditions of domestic enemy rear, soil, and environmental crops, and the nutrients are not balanced. Unreasonable coordination of elements

Domestic similar products have poor effect on activating soil, incomplete absorption by plants, insignificant effect of anti-stress membrane structure components, poor durability and controllability in drought resistance and nutrient supply, which affect its drought resistance effect

Under this situation, all parts of the country are actively exploring the development of circular economy and research on realizing drought resistance and water conservation. However, due to technical factors and the influence of traditional agricultural models, there are very few feasible drought-resistant products, and drought resistance and abundance conservation in dry-farmed areas are still in the low-level stage. exploring
