Abstract

The invention relates to a humic acid-containing concentrated liquid compound fertilizer and a preparation method thereof. The humic acid-containing concentrated liquid compound fertilizer consists of humic acid, urea, potassium sulfate, potassium dihydrogen phosphate, phosphoric acid, ammonia, potassium nitrate, organic chelating rare earth and tap water. The preparation method of the humic acid-containing concentrated liquid compound fertilizer comprises the following steps of: firstly weighing the tap water according to a weight ratio, and putting the tap water in a reaction kettle; after the beginning of mixing and heating, weighing the humic acid, the urea, the potassium sulfate, the potassium dihydrogen phosphate, the phosphoric acid, the ammonia, the potassium nitrate and the organic chelating rare earth for standby according to the weight ratio, and putting the materials in the reaction kettle; mixing and heating to 50 DEG C to 60 DEG C, keeping for 2 hours to 3 hours, and cooling to 25 DEG C to 40 DEG C; putting the materials on a colloid mill; putting semi-finished products after grinding in a container to be cooled to normal temperature; metering and packaging the products after sampling inspection is qualified; and obtaining finished products of the humic acid-containing concentrated liquid compound fertilizer. The products have simple production process and low costs of raw materials and production, and can provide nutrition for the growth of crops, prevent and treat physiological diseases of the crops, and simultaneously ensure production increase of the crops and income increase of farmers.

Description

technical field [0001] The invention relates to a fertilizer, in particular, a concentrated humic acid-containing liquid compound fertilizer that provides nutrition for crop growth, prevents and treats physiological diseases of crops, and can significantly increase crop yield and a preparation method thereof. Background technique [0002] Humic acid is a macromolecular organic substance that exists widely in nature. It is widely used in various fields such as agriculture, forestry, animal husbandry, petroleum, chemical industry, building materials, medicine and health, and environmental protection, spanning dozens of industries. Especially the current promotion of ecological agriculture construction, pollution-free agricultural production, green food, pollution-free environmental protection products, etc., makes "humic acid" highly respected. Facts have proved that human life and survival are inseparable from humic acid. my country is rich in humic acid resources, with large...
