Abstract

The invention discloses a large particle humic compound fertilizer and a method for preparing thereof belonging to the agricultural fertilizer field. The fertilizer comprises a humic acid, an inorganic fertilizer, and a medium trace element, wherein the humic acid is prepared by repeating compound bacteria fermention of 70% of lignite and 30% of waste tobacco dust by weight ratio. The weight content summation of nitrogen, phosphor and potassium in the inorganic fertilizer accounts for not less than 20% of the total fertilizer, wherein the weight ratio of nitrogen, phosphere and potassium is 10:4:6. The fertilizer has advantages of high fertilizer efficiency, long fertilizer efficiency and can improve the trophic structure of soil.

Description

technical field [0001] The invention relates to the field of agricultural chemical fertilizers, in particular to designing compound fertilizers. Background technique [0002] Chemical fertilizers are one of the most important means of production in modern times. At present, conventional compound fertilizers at home and abroad are generally powdery or small-grained inorganic fertilizers, which are highly volatile so that the effective substances in them cannot be effectively absorbed by crops. At the same time, due to the long-term use of inorganic fertilizers, the current soil nutrient element structure is unbalanced. Contents of the invention [0003] The embodiment of the present invention provides a fertilizer with high fertilizer efficiency and long fertilizer effect, which can improve the nutritional structure of soil. [0004] The embodiment of the present invention provides a method for preparing fertilizer. The prepared fertilizer has high fertilizer efficiency a...
