Abstract

The invention relates to a fast-dissolving water-soluble fertilizer, which comprises the following raw materials (by weight): 5-40 parts of humic acid, 0.1-2 parts of polyaspartic acid, 15-25 parts ofurea, 5-15 parts of potassium dihydrogen phosphate, 5-15 parts of ammonium superphosphate, 1-4 parts of a disintegrant, 20-30 parts of potassium nitrate, and 1-5 parts of a surfactant. The water-soluble fertilizer of the invention is an organic-inorganic composite water-soluble fertilizer, which can be quickly dissolved to promote rapid absorption of nutrients by plants, helps improve utilizationratio of nutrients and enhance the quality and yield of plants, can avoid soil pollution after application, and can meet the requirements of drip irrigation micro-spray. The fertilizer of the invention also has a good slow-release function. The nutrients are slowly released into the soil for crop absorption, and the synergistic effect of the various raw materials has a greater effect of promotingfertilizer efficiency and nutritional balance of the fertilizer.

Description

technical field [0001] The invention relates to a fertilizer, in particular to an instant water-soluble fertilizer and a preparation method thereof. Background technique [0002] Traditional fertilizers are artificially spread or mechanically planted. With the development of modern agriculture and the demand for water and fertilizer conservation, water and fertilizer integrated irrigation and fertilization technology is improving fertilizer utilization, saving agricultural water, reducing ecological environment pollution, and improving crop quality. And it shows obvious advantages in terms of reducing labor force. Therefore, water-soluble fertilizer or flushing fertilization suitable for drip fertigation has become a new type of environmentally friendly fertilizer suitable for high-efficiency agriculture and sustainable agricultural development. Water-soluble fertilizers refer to multi-element compound fertilizers that can be completely dissolved in water. Compared with tra...
