    1. Purging of leaves and weeds. In general, leaves and weeds are high in nitrogen. Such as fresh poplar leaves nitrogenous fresh elm leaves, fresh locust leaves, fresh purple locust leaves.

    leaves, fresh dogtail grass.

    Fresh cang. Fresh thorns are mixed with weeds on average. Fresh leaves and weeds should be dried for half a day, and then 30 of the amount of fresh grass should be added to the fine soil. When making, a layer of raw materials can be spread on the spot, sprinkled with a layer of human feces according to the amount of raw materials in the layer of 10, and then sprinkled with a layer of 2 3 inches thick fine soil, layer by layer to 5,000 6,000 pounds, sealed with mud outside, soaked for 30 35 days, smash the compost pile and then seal it, and the fertilizer will be completely decomposed after 50 days.

    2. Crop straw making. Sun-dried corn, sorghum, wheat, straw and other straws contain an average nitrogen. Because crop straw contains cellulose.

    And the horn is higher, not easy to rot, so when making manure, you can use straw, manure, fine soil "three-in-one" method, the proportion of the three is: straw 60% (1 day before the soaking with water), rotten manure 1000, fine soil 30%, when making, first lay a layer of 3 5 inches thick soil, and then spread a layer of 1 foot thick dry stalks, and sprinkle about 1% lime water.

    and ammonia to replenish the nitrogen source needed for microbial activity and to regulate the pH of the compost pile.

    Then spread a layer of 3 4 inches thick manure (donkey, horse manure is the best), pile up in turn, 5,000 6,000 pounds per pile, seal with mud outside, turn over the compost pile in about 40 days, splash an appropriate amount of water, continue to make after mud sealing, and then after about 20 days can be decomposed.

    3. Preparation of aquatic plants in lakes and rivers. Aquatic.

    The average nitrogen content, phosphorus and potassium content of weeds is equivalent to 24 kilograms of ammonium sulfate per thousand catties of fresh grass.

    20 kg of superphosphate, 13 kg of potassium sulfate. The proportion of raw materials is 30% finely crushed dry lake mud, 60% dried aquatic weeds, and 10% manure or donkey and horse manure. Use these raw materials to pile up a layer of lake mud, a layer of aquatic plants, and a layer of manure, and the mud seal is drunk, and it is manually turned over once after 1 month, and then the mud is sealed for about 20 days to rot.

    4. The preparation of fishy fertilizer in the lake and sea. The main raw materials are lake snails, clams and other animals. Most of the nitrogen contained in this kind of fishy fertilizer is protein, and phosphorus is mostly organic phosphorus, which can not be directly absorbed by crops, and must be converted into fast-acting nitrogen and phosphorus by microbial decomposition through fermentation before being absorbed and utilized by crops.

    The method of making the fishy fertilizer of the lake and the sea is: first, the collected snails and clams are pressed into a paste with stones, and the raw materials are made according to the ratio of 1 kg of fishy fertilizer and 2 3 kg of fine soil, and after mixing, put it into the pit of 3 4 cubic meters, splash a small amount of water on the top, and then seal it with mud, and it can be decomposed after 40 days.

    1. Loose accumulation method.

    Pile up the leaves in the manure accumulation field and keep the ventilation good during the accumulation process. Under high temperature conditions, livestock manure and urine decompose quickly, and in a short period of time, well-rotted organic fertilizer can be produced.

    2. Tight stacking method.

    The leaves are piled up layer by layer in the manure accumulation site, and pressed as they are piled up. If it is too dry, you can add an appropriate amount of water to keep it moist, the height of the compost pile is suitable to 2 meters, and when the accumulation is completed, seal the compost pile with soil, and the temperature is generally kept at 15 to 35.

    After about 3 to 4 months, the organic fertilizer can reach a semi-decomposed state, and it can be completely decomposed after more than 6 months.

    3. Loose and tight cross stacking method.

    The use of loose and tight alternating accumulation can not only shorten the decomposition time of organic fertilizer, but also reduce nitrogen loss. Pile the fresh leaves loosely outside the circle about a metre high without pressing them tightly to allow them to ferment. Generally, after 2 to 3 days, the temperature in the compost can reach 60 to 70, and then you can continue to pile up fresh organic fertilizer, so that it is stacked layer by layer until the height is 2 meters to meters.

    Seal the compost pile with soil to maintain the temperature, block the air ingress, and prevent fertilizer loss and large amounts of water evaporation. Generally, it can reach a semi-rotted state in 1 and a half to 2 months, and it can be completely rotted after 4 months.
