High-concentration anti-crystallization humic acid water soluble liquid fertilizer

Abstract

The invention relates to the field of agricultural fertilizer, in particular to high-concentration anti-crystallization humic acid water soluble liquid fertilizer. The fertilizer is suitable for fertilization to vegetable and fruit crops. The effective component of the fertilizer is prepared from the following raw materials in percent by weight: 8 to 12 percent of glycerol, 12 to 18 percent of mannitol, 12 to 18 percent of urea, 20 to 30 percent of monopotassium phosphate, 9 to 15 percent of potassium hydroxide, 6 to 10 percent of potassium humate, and 12 to 18 percent of water. The fertilizersolves the problems of high water-soluble fertilizer residue, low content, insufficient fertilizer efficiency and low utilization.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, namely a high-concentration anti-crystallization humic acid water-soluble liquid fertilizer. Suitable for fertilizing vegetable and fruit crops. Background technique [0002] In the prior art, the humic acid water-soluble fertilizers that exist in the market have many disadvantages. The raw materials react with each other to form insoluble substances. Due to the limited solubility of inorganic salt raw materials and low concentration, the production cost is high. Pure inorganic salts are used as The absorption rate of nutrient crops is low. At the same time, in the integration of water and fertilizer in modern agriculture, sprinkler irrigation and dripper facilities are used. If the residue rate of water-soluble fertilizers is too high, it will lead to pipe plugging and other phenomena, and the uncontrollable reaction between materials will lead to fertilizer efficiency. decrease, and the...
