Humic acid organic biological composite fertilizer and preparation method thereof

Abstract

The invention provides a humic acid organic biological composite fertilizer and a preparation method thereof. The above novel composite fertilizer mainly includes activated humic acid, chicken manure and biological fungi, wherein a weight ratio of the activated humic acid to the chicken manure is 1:2-2.5, and preferably 1:2.2. The quantity of biological fungi is 30 millions / g. The humic acid organic biological composite fertilizer can effectively improve soil, raises the soil fertility, improves the permeability of the soil, improves the water and fertilizer conservation capability of the soil, converts hard-to-use phosphorus, potassium and medium and trace elements in the soil into crop-available effective nutrients, prevents activity of pathogens in the soil, and improves the disease resistance of 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 pot...
