Spruce culture medium prepared from cassava stalk

Abstract

The invention provides a spruce culture medium prepared from a cassava stalk. The cassava stalk and the spruce skin are respectively smashed into different sizes of particles, after treatment of pile fermentation, the ectomycorrhizal fungi of the spruce is added into the particles and then blended uniformly so as to obtain the spruce culture medium, the spruce culture medium comprises the following raw material components according to parts by weight: 4-5 parts of pile fermenting cassava stalk base material and 5-6 parts of pile fermenting spruce skin base material, the pile fermenting cassava stalk powder base material comprises 100 parts of cassava stalk powder, 100 parts of chicken manure, 0.1 part of cassava powder, 5 parts of superphosphate, 0.05 part of slaked lime powder, and 0.02 part of an enzyme microorganism agent, and the pile fermenting spruce skin powder base material comprises 100 parts of spruce skin powder, 2 parts of urea, 0.02 part of slaked lime powder, and 0.01 part of 95% hymexazol wettable powder. The spruce culture medium makes full use of processing residue of agriculture and forestry, so that the culture of seedling cost is lowered; and the culture medium has the particles with proper size, has a loose structure, is high in organic matter content, contains multiple microelements, is proper in power of hydrogen, has less germ, and is very suitable for growth of spruce seedlings.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to a fir cultivation substrate prepared from cassava stalks. Background technique [0002] Chinese fir (Cunninghamia lanceolata) grows rapidly, has excellent materials, is easy to process, and has a wide range of uses. It is one of the important fast-growing timber tree species in South China. The existing Chinese fir forest area in Guangxi exceeds 1.25 million hectares, and more than 500,000 mu of forests are renewed every year, requiring a large number of afforestation seedlings. [0003] Cassava is one of the main economic crops in southern my country. After farmers harvest cassava, most of the remaining cassava stalks are discarded or burned, except for a very small part as seeds, resulting in waste of resources and air pollution. Cassava stalks are rich in cellulose, hemicellulose, lignin, protein and mineral elements, which can be used to cultivate edible fungi. At th...

[0003] Cassava is one of the main economic crops in southern my country. After farmers harvest cassava, most of the remaining cassava stalks are discarded or burned, except for a very small part as seeds, resulting in waste of resources and air pollution.

Cassava stalks are rich in cellulose, hemicellulose, lignin, protein and mineral elements, which can be used to cultivate edible fungi. At the same time, cassava stalks are light in weight, loose in structure, easy to decompose, and have better water absorption and moisture retention. They are also the best choice for making cultivation substrates. Good material, but there is no related report
