Biological organic fertilizer refers to a kind of fertilizer with both microbial fertilizer and organic fertilizer effect, which is composed of specific functional microorganisms and organic materials mainly derived from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and processed and decomposed.
Fermentation fertilizer operation process:
1. The general dosage of bacteria is 0.2%--0.5%.
2. Raw materials and requirements:
Main materials: fruit residue, edible fungus residue, distiller's lees, beer lees, sugar residue, vinegar residue, starch residue, cassava residue, citric acid residue, soy sauce residue, monosodium glutamate residue, powder residue, bean curd residue, medicinal residue, oil residue, oil cake meal, bran, cotton rapeseed meal, sludge, sugar factory brewery residue, leftover food, human and animal feces and other materials.
Auxiliary materials: all kinds of crop straw, leaves, weeds, melon vines, straw, pine shell, peanut shell, sawdust, husk powder, chaff and other dry, crushed, high carbon.
3, raw and auxiliary material ratio: main material: auxiliary material =5:1-3:1.
4, water controls at 60-65%, hand grasp the material into group just water.
5, according to the requirements of the bacteria, main materials and auxiliary materials all mixed evenly, you can use the mix machine.
6, the ambient temperature is above 15℃, a pile of material is not less than 4 square, pile into 1.5 ~ 2 meters wide, about 0.6 meters high, unlimited length of the pile, and use a stick to open the air hole in the pile.
7. When the pile temperature rises to 50℃, it starts to tip over once a day. If the pile temperature exceeds 65℃, it will tip over again. The temperature should be controlled below 70℃. Too high temperature will affect the nutrients.
8. Rot mark: the heap temperature is reduced, the material is loose, there is no original smell of the material, slightly ammonia smell, white mycelium is produced in the heap.
9, mature raw fertilizer: direct use, production of commodity organic fertilizer, biological organic fertilizer, organic and inorganic compound fertilizer, biological organic and inorganic compound fertilizer, etc.
