Embodiment Construction

[0037] The following is attached figure 1 The application is described in further detail.

[0038] The embodiment of the present application discloses a method for on-site resource utilization of agricultural and forestry waste. refer to figure 1 , an in-situ resource utilization method for agricultural and forestry waste, comprising the following steps:

[0039] S1. Dig a fermentation tank; dig a 25-35 cm deep pit on the ground near the agricultural and forestry waste as a fermentation tank.

[0040] S2. Laying an insulating cloth; laying an insulating cloth for isolating the agricultural and forestry waste from the outside world in the fermentation tank, and the insulating cloth in this embodiment is a transparent plastic cloth. The area of ​​the transparent plastic cloth is much larger than the area of ​​the bottom of the fermentation tank, and the transparent plastic cloth is laid on the bottom of the fermentation tank and the peripheral wall of the fermentation tank, a...

Abstract

The invention relates to an agricultural and forestry waste on-site resource utilization method, and belongs to the field of waste treatment. Laying isolation cloth in the fermentation tank, wherein the edge of the isolation cloth is positioned outside the fermentation tank; loading the crushed agricultural and forestry wastes into a fermentation tank; urea is added into the agricultural and forestry waste to adjust the carbon nitrogen ratio to 20-30: 1; the edge of the isolation cloth covers the agriculture and forestry garbage, so that the isolation cloth completely wraps the agriculture and forestry garbage; the agricultural and forestry garbage becomes a soil conditioner after being decomposed and fermented for 55-65 days in the isolation cloth; and the soil conditioner is backfilled into the soil to improve the soil environment. The fertilizer has the effect of improving the soil environment.

Description

technical field [0001] The present application relates to the field of garbage disposal, in particular to a method for on-site resource utilization of agricultural and forestry garbage. Background technique [0002] Agricultural and forestry waste is an important member of waste, an important biomass resource, and an important renewable resource. The energy conversion and utilization of agricultural and forestry waste is one of the research hotspots in the field of renewable energy. my country is a large agricultural country, and a large amount of agricultural and forestry waste is produced every year. Therefore, it is of great significance to properly dispose of agricultural and forestry waste. [0003] At present, the way to deal with agricultural and forestry waste is usually to crush the agricultural and forestry waste and directly apply it to the soil to increase the fertility of the soil. In this way, the serious environmental pollution caused by incineration of agric...
