Abstract
An organic slow-release fertilizer belongs to the technical field of chemical fertilizers. The present invention consists of the following materials: 10-30 parts of polybutylene succinate, 10-30 parts of dimethylacrylamide, 0.1-0.2 parts of amino acid, 0.5-0.9 parts of sodium alkylsulfonate, 40-60 parts of urea 10-25 parts of sawdust, 5-10 parts of polyisoglutaric acid, 10-30 parts of bran, 10-20 parts of humic acid, 2-5 parts of potassium sulfate, 3-5 parts of nitrogen-fixing bacteria fertilizer, 0.5 parts of calcium -1.2 parts, magnesium 0.2-1.5 parts, iron 0.4-0.8 parts, boron 0.1-0.3 parts. The invention adds a water-retaining agent with a large specific surface area and a porous physical irregular water-absorbing structure, which further improves the water-retaining and water-absorbing properties of the fertilizer, has excellent gel strength and high salt and alkali resistance, and is biodegradable without affecting The components of the soil improve the lodging resistance, disease resistance and drought resistance of crops, and the crop absorption rate is high.
Description
technical field [0001] The invention relates to a fertilizer and belongs to the technical field of chemical fertilizers. Background technique [0002] Dry early water shortage is an important factor restricting the development of agriculture and accelerating land desertification in our country. According to relevant national statistics, my country's desertified land area is 2.622 million km 2 , accounting for 27.4% of the total land area, and the annual direct economic loss due to desertification reaches 54 billion yuan. Large-scale crop failures often occur in many areas. my country's agricultural water consumption accounts for about 80% of water resource consumption. However, the global water resource crisis makes irrigated agriculture must also take the development path of water conservation and water conservation. Therefore, improving the water use efficiency of farmland is the central task of our country's agriculture. [0003] In recent years, the use of water-abso...
