The biogas fertilizer kills the parasite eggs and harmful bacteria after being fermented by biogas, and at the same time enriches the nutrients, which is a high-quality organic fertilizer. It can be used to grow vegetables, not only can increase fertilizer efficiency, but also reduce the use of pesticides and fertilizers. The vegetables produced are deeply loved by consumers. Compared with vegetable fields without biogas fertilizer, the yield can be increased by about 30%, and the market sales price is also better than ordinary ones. The price is high.
1. Biogas residue as base fertilizer: The vegetables used for transplanting seedlings are used, and the base fertilizer is applied by acupoint application method. When the seedlings are transplanted, each 667 square meters is applied to the colonization hole with 2000 kg of decomposed biogas residue, and mixed with the round soil excavated by the open hole to be planted. For vegetables that are used for on-demand or large-area cultivation, the base fertilizer is generally carried out by means of strips. For melons and vegetables, such as pumpkin, melon, cucumber, tomato, etc., generally use large-cavity and large-fertilizer method. Each 667 square meters is mixed with 3000 kg of biogas residue, 35 kg of superphosphate, 100 kg of grass ash and appropriate amount of domestic garbage. Cover a layer of round soil with a thickness of about 5-10 cm. Immediately after planting, water is poured and covered with straw or straw.
Second, the biogas slurry for topdressing: generally adopts two methods: root external pouring and foliar spraying. The root drenched biogas slurry can be determined according to the variety of vegetables, generally 500-3000 kg per 667 square meters. Fertilization time is good for sunny days or evenings. It is not suitable for fertilization when rainy days or soils are too wet. The biogas slurry sprayed on the foliage is filtered through gauze before use. In the tender leaves of vegetables, the biogas slurry should be diluted 1 times in water, and the dosage should be between 40-50 kg. When spraying, the back of the leaves should be the main one, and it should be filled with liquid beads instead of dripping water. Spray time, morning dew after dry, summer is good in the evening, no spray at noon, rain. Leafy vegetables can be fertilized during any growing season of vegetables, and can also be sprayed with biogas slurry when combined with disease prevention and pest control. The melons can be grown in the bud stage, the flowering stage, and the fruit expansion period, and 3% potassium dihydrogen phosphate is added to the biogas slurry.
Third, note:
(1) When the biogas residue is used as the base fertilizer, the biogas residue must be piled up and decomposed outside the biogas tank.
(2) When the biogas slurry is topdressed, the concentration of the biogas slurry should be observed. If the biogas slurry is dark brown and has a certain consistency, it should be diluted after use.
(3) The biogas slurry is topdressed and topdressed, and the biogas slurry is generally parked outside the biogas tank for half a day.
(4) 7 days before the market is listed, the biogas fertilizer is generally not pursued.
