Problems solved by technology

Most of the existing seedlings at home and abroad use sandy soil, and a small part use matrix. The reason is that the resources of the matrix are few and the cost is high.

Embodiment

[0011] Mix 60% stevia slag, 30% waste shiitake mushroom sticks, and 10% animal manure in a weight ratio. After mixing, add a starter (microorganism) in a ratio of 8:100. During the process, the temperature is maintained at 55°C to 70°C, and the fermentation time is 22 days. Turn and stir once every 1-2 days until the end of fermentation. When the fermentation time is close, the fermentation temperature is measured. If the fermentation temperature does not rise any more, that is, when it is close to normal temperature (28° C.), the fermented substrate is sieved and classified, and packed according to different standards. Finally, the sieved coarse grains are crushed, returned to the pre-sieving process and mixed with the fermented substrate, and then sieved and packaged again to obtain a special substrate for seedling production using stevia rebaudiana dregs as raw materials.

Abstract

The invention relates to a recycling and seedling technology of organic wastes, in particular to a method for producing a special seedling substrate by utilizing stevia rebaudiana dregs as a raw material. The method comprises the following steps of: mixing 50 to 70 percent of stevia rebaudiana dregs, 20 to 40 percent of waste shiitake logs and 10 to 20 percent of animal feces in percentage by weight, stirring, fermenting, screening and packaging to obtain a finished product. The method comprises the detailed steps of: adding a leavening agent in mixed raw materials according to the proportion of 8: 100; evenly stirring and beginning to ferment with the fermentation temperature of 55 to 70 DEG C and the fermentation time of 20 to 30 days; screening and grading the fermented substrate, crushing coarse grains, returning to working procedures before screening and mixing the fermented substrate, screening again and finally packaging. By adopting the invention, resources are fully utilized, carbon dioxide is fixed and the pollution is reduced. The special seedling substrate produced by taking the stevia rebaudiana dregs as the raw material not only reduces the cost, but also has the characteristics of simple formula, easy operation, strong permeability, sufficient nutrients, and the like, and is suitable for seedling of all plants.

Description

technical field [0001] The invention relates to recycling of organic waste and seedling raising technology, in particular to a method for producing a special substrate for seedling raising by using stevia rebaudiana slag as a raw material. Background technique [0002] At present, in my country's stevia sugar production plants, the stevia slag after extracting stevia sugar has been treated as garbage, which pollutes the environment and is also a burden for manufacturers. The recycling of resources has become a prominent problem. In addition, due to the excessive use of oil and coal resources, a large amount of carbon dioxide emissions, resulting in global warming, droughts, floods, sandstorms and other natural disasters frequently occur, threatening people's lives and property, affecting economic development, so "carbon sinks" "became the focus of world attention. Afforestation has become one of the main measures to improve the ecological environment in our country. Seedlin...
