Long-acting water-soluble fertilizer and preparation method thereof

Abstract

The invention discloses a long-acting water-soluble fertilizer and a preparation method thereof. The long-acting water-soluble fertilizer contains a water-soluble nitrogenous fertilizer, a water-soluble phosphatic fertilizer, a water-soluble potash fertilizer, a biochemical fulvic acid potassium, 3, 4-dimethylpyrazole phosphate, chitosan oligosaccharide and 4-amido-1, 2, 4 triazole. The fertilizer has the advantages that the utilization rate of nitrogen phosphorus and potassium nutrients is increased, the effective period of the fertilizer is prolonged, the useless accumulation of phosphorus and potassium nutrients in soil and accumulation of nitrate in soil and fruit can be reduced, the soil is conditioned, and the disease resistance of plants is improved. The long-acting water-soluble fertilizer is simple in production process, low in cost, and beneficial for wide popularization.

Description

technical field [0001] The invention relates to a composition, in particular to a long-acting water-soluble fertilizer and a preparation method thereof. Background technique [0002] Due to the advantages of saving labor and quick results, water-soluble fertilizers have developed rapidly in my country in recent years, and they are also the development trend of modern agricultural fertilizers in my country. Water-soluble fertilizers use fertilizers and water together, which solves the problem that fertilization must be done in the field, and greatly improves labor efficiency. However, due to the short effective period of water-soluble fertilizers, they are frequently used. Ordinary water-soluble fertilizers are applied once every 7-10 days, about 3-7kg / mu each time. A large amount of nutrients accumulate in the soil, resulting in increasingly serious problems such as secondary salinization, soil compaction, and soil acidification. In some places, there are even phenomena suc...

Problems solved by technology

However, due to the short effective period of water-soluble fertilizers, they are frequently used. Ordinary water-soluble fertilizers are applied once every 7-10 days, about 3-7kg / mu each time. A large amount of nutrients accumulate in the soil, resulting in increasingly serious problems such as secondary salinization, soil compaction, and soil acidification. In some places, there are even phenomena such as small old seedlings, deformed fruits, dead sheds, and many diseases. A large amount of nitric acid accumulated in the soil Salt degrades the quality of vegetables and fruits and poses risks to human health
