Organic fertilizer, also known as farmyard fertilizer, is commonly used in the production of fruit trees, such as compost, circulatory fertilizer, manure fertilizer, green manure, cake fertilizer, river mud, poultry manure, human waste, and soil miscellaneous fertilizer. Most organic fertilizers need to be decomposed by microorganisms before they can be absorbed by the plant's root system. Therefore, they are also known as “delayed fertilizers†and can be used as basal fertilizers. Organic fertilizer can effectively improve soil physicochemical properties, improve soil water retention and fertility, and improve soil ventilation. First, compost: The crop straw, weeds, stems and leaves, leaves, livestock manure and other materials, layered, made through decomposition of microorganisms. During the propagation of microorganisms, appropriate temperature, moisture, ventilation, pH, etc. should be maintained to facilitate the reproduction of microorganisms. Second, ring fertilizer, fertilizer: including pigs, cattle, sheep, chickens, ducks and other livestock, animal dung, rich in nitrogen, phosphorus, potassium and other nutrients, after fermentation and maturity as base fertilizer application. Third, human fecal urine: decomposed human fecal urine, is a quick-acting nitrogen fertilizer, containing more nitrogen, phosphorus, potassium and organic matter can be combined with available phosphorus, potash fertilizer application. Ammonia volatilization loss into the urine, generally should be kept closed, if you add 2-3% of superphosphate, not only can fix nitrogen, but also to supplement the human fecal urine phosphate fertilizer. Human fecal urine can be applied to the ditch or acupuncture points, watered immediately after application and covered with soil to prevent evaporation. Be careful not to apply directly to human roots that have not been cooked. 4. Mud fertilizer: Sludge from ditch, pond, marshes, rivers, ponds and sewers in towns all belong to mud. Contains more organic, is a slow-lasting fertilizer, can be used as a base fertilizer orchard. 5. Green manure: Green manure plants are interplanted between the orchards. They can be fattened locally and used locally. There is no need for composting, picking, or field transportation, saving labor. The green manure crops in the orchard line are suitable for green manure with dwarf stems, many tillers, and well-developed root systems. 6. Urban garbage: The scraps and leaves of the chicken shells, leaves, eggshells, ash, etc. The garbage, which mainly comes from households, food markets, and roads, is a compound organic fertilizer. The three elements containing nitrogen, phosphorus, and potassium are similar to those of compost and manure. After application, the physical structure of the clay and loose soil can be improved.
