Humic acid organic biological compound fertilizer and preparation method thereof

Abstract

The invention provides a humic acid organic biological compound fertilizer and a preparation process thereof. The novel compound fertilizer mainly comprises active ingredients such as activated humicacid, chicken manure and biological bacteria. A weight ratio of active ingredients of the compound fertilizer, namely the activated humic acid and the chicken manure and the biological bacteria is asfollows: the weight ratio of the activated humic acid to the chicken manure is 1:(2-2.5), preferably, the weight ratio is 1:2.2; and the amount of the biological bacteria is 30 million strains per gram. The humic acid organic biological compound fertilizer can effectively improve the soil, improve the soil fertility, improve the soil permeability, improve the water and fertilizer retention capacity of the soil, convert phosphorus and potassium which are difficult to utilize by crops in the soil and medium and trace elements to act on available effective nutrients of the crops, antagonize the activity of pathogenic bacteria in the soil and improve the disease resistance of the crops.

Description

technical field [0001] The invention belongs to the field of agricultural chemical fertilizers, and in particular relates to a humic acid organic biological compound fertilizer and a preparation method thereof. Background technique [0002] The extensive application of chemical fertilizers in the 20th century has made an indelible contribution to increasing crop yield per unit area, accelerating land reproduction and reuse rates, and increasing the overall output of agricultural products, and has also played an important role in alleviating the contradiction between human needs and limited land . However, due to the long-term and excessive use of chemical fertilizers for many years, the organic fertilizers in the soil are insufficient and the proportions of various nutrients are out of balance, resulting in varying degrees of damage to the agricultural ecological environment, soil physical and chemical properties, and soil microbial flora, resulting in soil erosion. The...

Insufficient input of organic fertilizers leads to a decline in soil organic matter content, soil fertility, and high and stable yields

[0003] However, ordinary organic fertilizers have the disadvantages of being dirty, smelly, unhygienic, low in nutrient content, slow in action and inconvenient to use, and cannot meet the needs of modern agriculture.

Humic acid plays a magical role in plant growth because of its biological activity and special structural properties. Various compound fertilizers containing humic acid components have received great attention, but most of the common ones on the market are humic acid The compound fertilizer compounded with inorganic chemical fertilizers, the fertilizer effect of this compound fertilizer is still not comprehensive enough, and it is easy to cause many shortcomings similar to ordinary chemical fertilizers, such as insufficient soil fertility.
