First, reduce the loss of livestock manure and urine nutrients: improve the rims, do not leak water, do not leak fertilizer, easy to use the gasket; the floor of the rim is suitable for soil, the ratio of excreta to soil is 1:3 ~ 4, do Go to the diligent pad, circle once a day or every other day; if the excrement of the pen is not used temporarily, you should immediately pile up the outer mud seal to ensure the fertilizer effect.
Second, reduce the loss of human urine nutrients technology: human urine is rich in N, P, K. According to the measurement, if the human urine is not treated, it will be stored in the tank for 60 days, and the loss of N is about 90%. The method of reducing the loss of human urine nutrients is: the urine is accumulated in the tank or the pool, and must be covered in the tank or the pool to prevent evaporation, preferably stored for 7 to 10 days, to reduce the accumulation time to save nutrients.
Third, reduce the loss of manure nutrient technology: First, repair the toilet, septic tank, to achieve anti-seepage, leak-proof, rain-proof, and cover the closed; Second, change the use of methods, that is, change the application as a sparse application, will The mature manure after decomposing is best applied to the soil after dilution. The time of decomposing is generally 6 to 7 days in summer and 15 to 20 days in other seasons. Thirdly, human feces and urine should be strongly promoted.
Fourth, reduce the loss of plant ash nutrient technology: Because of the large amount of potassium carbonate, the plant ash is the only alkaline potassium fertilizer in the farmyard manure. Human excrement and manure are all acidic organic fertilizers, so the two are relatively acidic, neutralized, and the nutrients are lost. According to the measurement, after the plant ash and human excrement were mixed at a ratio of 1:1.5, after storage for ten days, the loss of N was about 27.4%, and the loss of N by storage for three months was about 85.9%. Therefore, in the work of composting and fertilizing, it is necessary to vigorously promote the monocropping of plant ash, single storage, and single use. It is forbidden to pour the ash into the organic fertilizer, and at the same time prevent the ash from being leached by the rain.
