因为沼气发电机组发电后沼渣沼液始终是在密闭的发酵池内发酵沤制的，水溶性很大，养分损失少，营养元素齐全，肥效高、质量优。沼渣沼液还含有多种微量元素和17种氨基酸。所以沼气发电后的沼渣沼液可做一下如此处理。

Since the biogas generator set generates electricity, the biogas residue and liquid are always fermented and retted in the closed fermentation tank, with great water solubility, less nutrient loss, complete nutrient elements, high fertilizer efficiency and excellent quality. Biogas residue and biogas slurry also contain a variety of trace elements and 17 kinds of amino acids. Therefore, the biogas residue and slurry after biogas power generation can be treated in this way.

1、作大田作物施肥。可以用作基肥和追肥方法与普通农家肥一样施用。作秧苗追肥、则须稀释，1／3桶沼液，冲满2／3水淋施。

1. Fertilize field crops. It can be used as base fertilizer and top dressing, and applied in the same way as ordinary farm manure. For top dressing of seedlings, it is necessary to dilute 1 / 3 of the barrel of biogas slurry, flush 2 / 3 of the water and spray it.

2、作花生施肥。作基肥，一将沼液泼淋于整好的花生地上，再、耕耙一次。种上花生每亩施30担。二是开好行后，将沼液淋于行沟，再种花生，每亩施20担。

2. Fertilize peanuts. As the base fertilizer, once the biogas slurry is splashed on the finished peanut field, it is ploughed and raked again. Each mu planted with peanuts is applied with 30 tons. Second, after opening the row, drench the biogas slurry in the row ditch, and then plant peanuts, applying 20 tons per mu.

3、作瓜菜施肥。瓜菜幼苗时用沼肥，以1／3桶沼液冲2／3桶水淋根部。以后可以直接施用。

3. Fertilize melons and vegetables. The seedlings of melons and vegetables are treated with biogas fertilizer, and the roots are drenched with 1 / 3 barrels of biogas slurry and 2 / 3 barrels of water. It can be directly applied later.

4、种蘑菇用。用沼渣与基料堆沤种蘑菇，蘑菇产量可提高30％，且菇鲜嫩，出菇速度快，菇球均匀，质量好。

4. I grow mushrooms. By composting mushrooms with biogas residue and base materials, the yield of mushrooms can be increased by 30%, and the mushrooms are fresh, tender, fast, uniform and of good quality.

5、作果树施肥。各种果树都可以施沼肥。特别是香蕉、柚子、龙眼、荔枝、杨桃、三华李、黄皮、柑橙类果树施用沼肥，对提高果品品质尤为显著。多数用作催花、保花、保果、壮果肥。每株淋一桶至一担。也可作雾肥喷淋施用。

5. Fertilize fruit trees. All kinds of fruit trees can be fertilized with biogas. In particular, the application of biogas fertilizer to banana, grapefruit, longan, litchi, carambola, Sanhua Plum, Huangpi, citrus and orange fruit trees is particularly significant to improve the quality of fruit. Most of them are used for accelerating flowers, protecting flowers, protecting fruits and strengthening fruits. Drench each plant with one bucket to one load. It can also be used as spray fertilizer.

6、沼液养猪。沼液中含有多种对猪生长有利的物质，其中属于需的氨基酸总量可达52％，是一种饲料添加剂。所以用沼液喂猪可增重15％以上。一般小猪每餐加沼液1斤，中猪1.5至2斤，大猪2至2.5斤。开始初喂时，适当少量，适应后，逐步加至足量。

6. Raising pigs with biogas slurry. Biogas slurry contains a variety of substances beneficial to pig growth, of which the total amount of amino acids required can reach 52%. It is a feed additive. Therefore, feeding pigs with biogas slurry can increase their weight by more than 15%. Generally, 1 kg of biogas slurry is added to each meal for small pigs, 1.5-2 kg for medium pigs and 2-2.5 kg for large pigs. At the beginning of initial feeding, a small amount should be used appropriately, and then gradually added to a sufficient amount after adaptation.

7、沼肥养鱼。沼肥养鱼主要是利用沼液中多种营养元素，提高塘水肥力和增加浮游生物，供鱼食用，同时，可以预防鱼病。一般每亩面积的鱼塘一次加沼液300至400斤，一周2次。专养塘角鱼的，每次加沼液400至500斤，更快长大。

7. Fish farming with marsh manure. Biogas fertilizer fish culture mainly uses a variety of nutrients in biogas slurry to improve the fertility of pond water and increase plankton for fish consumption, and at the same time, it can prevent fish diseases. Generally, 300 to 400 kilograms of biogas slurry are added to the fish pond per mu, twice a week. Those who specially raise pond horned fish can grow up faster by adding 400 to 500 kilograms of biogas slurry each time.
