Compound microbial water-soluble fertilizer and its preparation method

Abstract

The invention discloses a compound microbial water-soluble fertilizer and a preparation method of the compound microbial water-soluble fertilizer. The fertilizer comprises the following components in percentages by weight: compound microbial fermentation liquid 20-30%, amino acid powder 27-30%, urea 5-9%, ammonium dihydrogen phosphate 5-10%, potassium sulfate 10-15%, secondary element and trace element 1-5%, and water 15-20%. The method comprises performing aerobic fermentation on brown sugar, water, soybean milk and enzyme microorganism to obtain the compound microbial fermentation liquid, sequentially adding the secondary element and trace element, ammonium dihydrogen phosphate and potassium sulfate into a container filled with water, stirring at 70-90 DEG C until the material is dispersed uniformly and free of particle aggregates, cooling to 40 DEG C, sequentially adding the amino acid powder, urea and the compound microbial fermentation liquid, stirring for dissolution, and adjusting pH to be neutral. The compound microbial water-soluble fertilizer of the invention is rich in nutrients and easily soluble in water, prevents soil from hardening, promotes the growth and development of crop, improves the yield and quality of crop, and is suitable for drip irrigation, flushing and spraying.

Description

technical field [0001] The invention relates to a microbial fertilizer, in particular to a composite microbial water-soluble fertilizer, and also relates to a preparation method of the fertilizer. Background technique [0002] In recent years, with the continuous development of agricultural production, the output of various crops has increased significantly, and the amount of fertilizer required is also increasing. The base fertilizer and seed fertilizer obviously cannot meet the nutrient needs of high-yield crops. A large number of research data and production practice results show that according to the law of fertilizer demand of fruit trees, vegetables and field crops, topdressing quantitative nutrient elements during the growth period of fruit trees, vegetables and field crops has a significant effect on improving the yield and quality of fruit trees, vegetables and field crops. important role. Because fruit trees, vegetables and field crops are crops with a long period...

Problems solved by technology

[0003] At present, there are many kinds of water-soluble fertilizers on the market. Some products add a large amount of chemical accelerators, such as sodium nitrophenolate produced by Shandong Haiyuan Biochemical Technology Co., Ltd. Although the yield has increased, it is easy to cause soil compaction, premature aging of plants, and lead to crop failure. Quality decline, endangering human health

Some products use plant straw or weathered coal as raw materials. For example, Wanhexin International Biochemical Co., Ltd. produces organic flushing fertilization, which has poor water solubility and is difficult to use for flushing.
