Special selenium-rich microbial organic fertilizer for citrus and preparation method thereof

Abstract

The invention discloses a special selenium-rich microbial organic fertilizer for citrus and a preparation method thereof. The special selenium-rich microbial organic fertilizer is prepared from the following raw materials in parts by weight: 30-40 parts of wormcast cultured by cow dung, 10-20 parts of silkworm excrement, 15-20 parts of edible mushroom residues, 8-11 parts of tea leaf residues, 8-12 parts of abamectin mushroom residues, 5-15 parts of peanut cakes, 0.1-0.3 part of microbial zymophyte and 1.1-1.5 parts of 60-120-mesh organic selenium. The organic fertilizer disclosed by the invention is specially used for promoting citrus growth, has the advantages of long and stable fertilizer efficiency, and has the characteristics of simple process, wide raw material source and the like; meanwhile, the organic matter content is high, the soil quality can be improved, the soil structure is improved, and ecological balance is kept.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a special selenium-enriched microbial organic fertilizer for citrus and a preparation method thereof. Background technique [0002] The large and long-term use of chemical fertilizers in agricultural planting in my country has led to the lack of organic matter in the soil, the imbalance of nitrogen, phosphorus, and potassium, and the seriousness of agricultural diseases and insect pests. Excessive use of chemical fertilizers not only causes a large amount of energy consumption, but also causes agricultural water sources and soil environmental pollution. It will also cause soil compaction, crop production reduction, damage to the ecological environment, and eutrophication of water bodies, affecting the health of humans and animals, etc.; The return of nutrient components to the land is of great significance for improving soil, restoring microecology, restoring fertility, vigorousl...
