A high-absorptivity slowly-decomposed fertilizer

Abstract

A high-absorptivity slowly-decomposed fertilizer is disclosed. The fertilizer is characterized by comprising following raw materials by weight: 20-30% of fulvic acid, 15-25% of dry azolla powder, 8-15% of ultrafine rock phosphate, 10-15% of potassium chloride, 3-5% of ferrous sulphate, 6-8% of ammonium sulfate, 10-15% of calcium nitrate, 3-6% of boric acid, 2-3% of magnesium sulfate, 4-5% of sulfur powder, 1-2% of bentonite and 2-3% of an inducer. The raw materials of the fertilizer are matched reasonably. The fertilizer improves soil physical and chemical properties and improves the soil structure. By the compatibility of adopting purified materials rich in fulvic acid as main materials and adopting nitrogen, phosphorus, and other organic matters as auxiliary materials, effects of increasing yields and increasing fertility are achieved. Organic and inorganic are combined. The fertilizer is high in fertility, small in using amount, easy in manufacturing, low in production cost, free of pollution to the environment in production and using processes, and capable of increasing the yield.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, and in particular relates to a fertilizer with a high absorption rate for relief. Background technique [0002] Organic fertilizers are rich in organic matter and nutrients needed for crop growth. They can not only provide the nutrients needed for crop growth, improve the soil, but also improve crop quality, increase crop yield, promote high and stable crop yields, maintain soil fertility, and increase fertilizer efficiency. Utilization rate, reduce production cost. The full and rational use of organic fertilizers can increase crop yields, improve soil fertility, improve the quality of agricultural products, and increase the effectiveness of soil nutrients. [0003] Many places in my country are rich in weathered coal resources, and its geological reserves reach as much as 100 million tons. Its grade is very high, that is, it contains 27 kinds of nutrients such as nitrogen, phosphorus, po...

Problems solved by technology

[0004] At present, people who use fertilizers only pay attention to the effect of fertilizers to increase production, and ignore the pollution of fertilizers to the soil environment, especially to products.

It not only poses a serious environmental problem, but also poses a danger to human health. Therefore, in recent years, non-polluting organic food and green food have aroused people's interest. However, in the production process of safe food, people have noticed that there are more pollution from pesticides and additives.
