Abstract

The invention relates to a special slow release water-soluble fertilizer for soybeans, and a preparation method thereof. Raw material components of the special slow release water-soluble fertilizer for soybeans comprise 140-150 parts of a urea formaldehyde fertilizer, 40-50 parts of diammonium phosphate, 60-70 parts of potassium dihydrogen phosphate, 50-60 parts of potassium nitrate, 10-15 parts of a chelated medium and trace element premix, 3-4 parts of sodium molybdate, 10-15 parts of soluble organic matters, 4-5 parts of a solubilizer and 3-5 parts of an amide hydrogel material. The invention also relates to the preparation method of the special water-soluble fertilizer for soybeans. Parts of nitrogen and phosphorus nutrients of the special slow release water-soluble fertilizer for soybeans have a slow release effect, and the special slow release water-soluble fertilizer for soybeans also contains a small amount of soluble organic matters, has comprehensive nutrition, meets soybean demands, accords with the nutrient absorption rule of a soybean generation period, can increase the yield of soybeans and improve the quality of the soybeans, and has improved fertilizer effect utilization rate.

Description

technical field [0001] The invention relates to a special slow-release water-soluble fertilizer for soybeans and a preparation method thereof. More specifically, the invention relates to a special slow-release water-soluble fertilizer for soybeans and a preparation method thereof, belonging to the field of special water-soluble fertilizers. Background technique [0002] Soybeans have comprehensive nutrition and rich content. The protein content is 2 times higher than that of pork and 2.5 times that of eggs. The amino acid composition of soybean protein is similar to that of animal protein, and the amino acid ratio is closer to the ratio required by the human body, so it is easy to digest and absorb. Soybeans are rich in inorganic salts such as calcium, phosphorus, magnesium, and potassium, as well as trace elements such as copper, iron, zinc, iodine, and molybdenum. my country is the hometown of soybeans. However, under the impact of foreign soybeans in recent years, my coun...
