[0002] The Qinghai-Tibet Plateau is famous for its unique soil types, including alpine meadow soil, alpine steppe soil and alpine cold desert soil. These soils are formed under cold and humid climatic conditions, are usually acidic, contain high organic matter and clay, and rich in total carbon content. However, due to the high altitude, low temperature and low precipitation in the region, the soil develops slowly, resulting in a slow decomposition of organic matter, which in turn affects the content of extractable organic carbon in the soil. Summary of the invention

The present invention uses agricultural by-products such as solid wood sawdust, vegetable bran, wheat bran, cattle and sheep manure as raw materials, accelerates the decomposition of organic matter through fermentation and the action of microbial composite strains, and increases the extractable organic carbon content in the soil. The present invention not only helps to improve soil structure and soil fertility, but also promotes plant growth, while realizing the resource utilization of agricultural waste, and has the characteristics of environmental protection and sustainability.

[0007] As an improvement, the solid wood sawdust comes from tree trunks, barks, leaves and the like.

[0008] As an improvement, the raw materials are calculated by weight as follows:

[0009] 4500 parts of solid wood sawdust, 100 parts of vegetable bran, 100 parts of wheat bran, 250 parts of cow dung, 250 parts of sheep dung, 30 parts of brown sugar, 40 parts of corn starch, and 100 parts of microbial composite strains.

[0010] The preparation method of the present invention comprises the following steps:

[0011] S1. Add water to the solid wood sawdust to make the moisture content of the solid wood sawdust reach 65%-75%;

[0012] S2. Vegetable bran, wheat bran, cow dung, sheep dung, brown sugar, corn starch and microbial composite strains are sequentially added to the wet solid wood sawdust and mixed evenly using an automatic mixer;

[0013] S3. After mixing, stacking and fermentation at a constant temperature;

[0014] S4. Fermentation takes 20-30 days, during which the compost is turned over at intervals;

[0015] S5. After fermentation, the raw materials are passed through a pellet machine to produce formed biomass fertilizer.

[0016] As an improvement, the stack in step S3 has a height of 1.6-2.2 meters and a width of 2.5-3.5 meters.

[0017] As an improvement, the operation method of turning the pile is: turning the pile once every 7-10 days, for a total of 2-3 times.

[0018] As an improvement, the compression ratio of the biomass fertilizer is 6.0, and the size of the formed particles is between 0.8 cm and 1.0 cm.

[0019] The present invention has the advantages that:

[0020] 1. The carbon-water biomass fertilizer used in the present invention has a wide range of raw materials, including solid wood sawdust, vegetable bran, wheat bran, cattle and sheep manure, etc. These by-products commonly found in agriculture and wood processing are not only easy to obtain but also low in cost. By converting these wastes into fertilizers, the present invention reduces production costs while also alleviating environmental pressure and achieving resource reuse and recycling.

[0021] 2. The present invention uses fermentation technology to effectively degrade cellulose in solid wood sawdust, thereby increasing organic matter in the soil and improving soil structure. In addition, with the assistance of composite microbial strains, the decomposition of organic matter is accelerated, the organic carbon content in the soil is increased, the growth of plants is promoted, and the yield and quality of crops are improved.

[0022] 3. The biomass fertilizer preparation method of the present invention is both environmentally friendly and efficient. Through fermentation and granulation treatment, the release of fertilizer is more uniform and slow, which not only improves the utilization efficiency of fertilizer, but also reduces the loss of chemical fertilizer. In addition, the application of biomass fertilizer helps to adjust the pH value of the soil, enhance the water and fertilizer retention capacity of the soil, improve the soil microecological environment, achieve friendly protection of the environment, and at the same time improve the sustainability of agricultural production.
