Abstract

The invention discloses an efficient slow-release organic fertilizer for rice. The efficient slow-release organic fertilizer contains the following raw materials: animal dung, crop straws, folium mori, distillers' grains, a compound microorganism bacterial agent, humus, modified zeolite powder, dolomite, montmorillonoid, ardealite and potassium chloride. By adding the raw materials including the compound microorganism bacterial agent, the modified zeolite powder, the humus and the like, the pathogenic bacteria in soil can be effectively inhibited, and comprehensive nutrients can be provided, so that the healthy and strong growth of crops can be maintained.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a high-efficiency slow-release organic fertilizer for rice. Background technique [0002] Although traditional inorganic chemical fertilizers have high nutrient content and rapid fertilizer effect, their fertilizer effect is strong but not long-lasting, and the effect of improving soil is not great, and even has side effects of destroying soil properties. The large-scale use of inorganic chemical fertilizers in agricultural production will bring such as Various problems such as quality decline, soil compaction, and water pollution. With the improvement of people's living standards, residents' demand for safe, hygienic and pollution-free organic and green food continues to increase. The majority of farmers urgently need to use organic fertilizers to improve the market competitiveness of agricultural products. Contents of the invention [0003] Based on the techn...
