Background
Over-application of chemical fertilizers for many years causes soil acidification and water eutrophication, seriously affects the soil quality of cultivated land and damages the ecological environment to a certain extent. The rise of the chemical fertilizer causes that farmers use the chemical fertilizer excessively in the process of pursuing the maximization of the yield per mu, and the quality of cultivated land is seriously influenced.
In recent years, the wide application of various chemical fertilizers and pesticides brings great harm to land and crops, and soil hardening, soil microbial environment deterioration, crop pesticide residue standard exceeding, quality reduction and the like generally exist. With the abuse of chemical fertilizers, the soil quality in all regions is remarkably reduced. The soil structure is seriously damaged, and beneficial microorganisms and organic matters in the soil are reduced to different degrees. Some nutrient substances in the soil are seriously lost, so that the self-purification capacity of the soil is weakened after the soil is polluted by heavy metal, the yield and the quality of agricultural products are reduced, and the resistance of the agricultural products to diseases and insect pests is reduced. Therefore, modern ecological agriculture is urgently needed to be built, and zero pollution of soil in the production process is realized while materials and energy are efficiently utilized.
For sustainable development of agriculture, pollution-free microbial fertilizers have come into the sight of people. As one of the main measures for effectively dealing with the problems, the appearance, use and popularization of microbial organic fertilizers are necessary requirements for agricultural sustainable development and also necessary results of continuous innovation of scientific and technical research and development. The biological organic fertilizer is prepared by taking livestock and poultry manure, municipal domestic waste, crop straws, agricultural and sideline products and organic wastes generated by food processing as raw materials, matching with a multifunctional fermentation strain agent, quickly deodorizing, decomposing, dehydrating and adding functional microorganisms. Compared with chemical fertilizers, the biological organic fertilizer has the greatest difference that the biological organic fertilizer contains various functional microorganisms, and is very beneficial to plants and soil; meanwhile, the fertilizer contains a large amount of organic matters, and after the fertilizer is applied to soil, the soil fertility can be increased, and the soil pollution can be improved; the fertilizer efficiency is more durable, and the quality of crops can be improved while the yield and the income are increased.
However, the existing bio-organic fertilizer still has the defects of long preparation period, high requirements on fermentation environment, field and process, easy leakage and secondary pollution in the fermentation preparation process, high cost of substances required to be added in the preparation process, unobvious yield increasing and income increasing effects, long time required for generating and stably sustaining beneficial effects and the like, and the defects limit large-scale and generalized use and production of the bio-organic fertilizer and are also important reasons that the existing bio-organic fertilizer still cannot impact the main stream status of fertilizers.

the preparation method of the dried orange peel-Pu ' er ripe tea soup fermentation water comprises the steps of mixing Pu ' er ripe tea with water according to the solid-to-liquid ratio of 5-10g/L, heating to boil, keeping boiling for 10-15min, filtering out tea soup, cooling to room temperature, and measuring the pH value of the Pu ' er ripe tea soup to be 8.5-10; the tea leaves are not used, because the nutrition of the Pu-Er ripe tea after long-time boiling is fully released into the tea soup, the tea leaves have no great utilization value, and the alkalinity of the tea leaves is stronger than that of the tea soup, the moist tea leaves are applied to the soil, on one hand, the mould and bacteria are easy to breed and attract insects in the process of rotting the tea leaves, on the other hand, the soil alkalinity is stronger, and the two phenomena are not beneficial to the growth of plants; filtering out tea soup, mixing pericarpium Citri Tangerinae and cooked Pu-erh tea soup at solid-to-liquid ratio of 30-45g/L, placing in another plastic barrel, sealing and fermenting at room temperature above 20 deg.C, and determining fermentation time according to temperature; during fermentation, the plastic barrel is opened immediately after obvious expansion, and the barrel is prevented from being broken by expansion; and (3) until the fermentation of the fermented product in the plastic barrel is completely fermented, keeping the plastic barrel in the original state and not expanding any more, then filtering the dried orange peel residue and other solid residues in the fermented product, keeping liquid, and measuring the pH value to be 4.0-5.5 to obtain the dried orange peel-Pu' er ripe tea soup fermented water.
Secondly, another plastic barrel is taken, potassium humate powder containing 80-85 wt% of organic matters, 30-35 wt% of humic acid, 8-12 wt% of potassium and 93-95% of soluble potassium humate powder is placed at the bottom of the barrel, the EM bacterial liquid obtained in the first step is added into the barrel, and the solid-liquid ratio of the potassium humate to the EM bacterial liquid is 150-; after adding, covering and shaking the mixture forcibly and uniformly, placing the mixture in an environment with the room temperature of more than 18 ℃ for reaction, and determining the reaction time according to the room temperature; during the reaction period, the condition of the plastic barrel is checked regularly, and when the obvious barrel shrinkage phenomenon occurs, the plastic barrel is opened immediately for ventilation; and (3) the barrel is not shrunk until the plastic barrel is kept in the original state, the reactants in the barrel react completely, organic matters in the potassium humate are fully released and decomposed by EM bacterial liquid, and the pH value is 6-7, so that the reaction liquid is obtained.
Thirdly, adding the dried orange peel-Pu' er tea cooked soup fermentation water obtained in the first step into the reaction liquid, fully and uniformly stirring, then covering and sealing the reaction liquid, placing the reaction liquid in a room temperature environment of more than 18 ℃ for fermentation reaction, wherein the fermentation reaction time is determined according to the temperature and is generally 3-5 days, and timely venting is carried out in the period; during the fermentation reaction period, on one hand, the alkalinity of the reaction liquid and the pericarpium citri reticulatae-Pu 'er ripe tea fermentation water can be further reduced, on the other hand, the reaction liquid and the pericarpium citri reticulatae-Pu' er ripe tea fermentation water are more fully mixed, fermented and reacted, organic matters are further decomposed, nutrient substances, trace elements and the like are more fully released, and the final finished organic fertilizer has very excellent comprehensive improvement effect on the comprehensive quality of fruits, vegetables, crops, flowers and the like; filtering the obtained oily reactant mixed with some insoluble precipitates, impurities and other solid residues after 3-5 days, filtering out solid impurities, and then placing the filtered reactant in a direct sunlight environment at 30-38 ℃ for sealed solarization for 3-5 days, wherein timely air release is noticed during the process; and after the insolation is finished, filtering out residual insoluble impurities and precipitates, and measuring the pH value to be 6.0-6.5 to obtain the oily finished product biological water-soluble fertilizer with uniform texture.
It should be noted that the potassium humate can be mixed with the pericarpium citri reticulatae-pu 'er ripe tea fermentation water for fermentation reaction only after the potassium humate is fully reacted with the EM bacterial liquid to generate a reaction liquid, and if the potassium humate is directly mixed with the pericarpium citri reticulatae-pu' er ripe tea fermentation water or is mixed with the pericarpium citri reticulatae-pu 'er ripe tea fermentation water before the potassium humate is completely reacted with the EM bacterial liquid, acid-base neutralization reaction can be generated between the potassium humate and the pericarpium citri reticulatae-pu' er ripe tea fermentation water, organic matters and nutrients in the potassium humate are inactivated to generate precipitates, so that the final finished product effect is greatly reduced, and even the manufacture is directly failed.
More preferably, after obtaining the reaction solution, before mixing the reaction solution with the pericarpium citri reticulatae-Pu' er ripe tea soup fermentation water, adding polyglutamic acid into the reaction solution, wherein the solid-to-liquid ratio of the added amount to the reaction solution is 10-20 g/L.
More preferably, after the polyglutamic acid is added, aspirin powder can be added, and the solid-liquid ratio of the addition amount to the reaction liquid is 20-25 mg/L.
