NOVELTY - Culture medium is made by smashing the stems of Manihot esculenta and the bark of Cunninghamia lanceolata. After pile fermentation and mixing, the obtained culture medium comprises 4-5 pts. wt. base material prepared by pile fermentation of Manihot esculenta stems and 5-6 pts. wt. base material prepared by pile fermentation of the Cunninghamia lanceolata bark. The base material prepared by pile fermentation of Manihot esculenta stems includes chicken manure, tapioca, calcium superphosphate, slaked lime and enzyme-producing microorganisms.    USE - Culture medium (claimed).    ADVANTAGE - Using cassava rod and fir skin of fir prepared culture medium, where the agricultural and forestry processing residue of full use of local materials, it can protect environment and reduces the breeding cost, improves the organic matter content, adding urea stack anger fir skin, which can reduce, promote the activity of microorganism, it is good for plant root development, has strong buffering property can resist nutrient sialic alkali degree and salinity change of the plant root.    DETAILED DESCRIPTION - Culture medium is made from the stems of Manihot esculenta, where the stems of Manihot esculenta and the bark of Cunninghamia lanceolata are smashed into particles of different size. After pile fermentation and uniform mixing, the obtained culture medium comprises 4-5 pts. wt. base material prepared by pile fermentation of the Manihot esculenta stems and 5-6 pts. wt. base material prepared by the pile fermentation of the Cunninghamia lanceolata bark. The base material prepared by the pile fermentation of the Manihot esculenta stems comprises 100 pts. wt. powdered stems of Manihot esculenta, 100 pts. wt. chicken manure, 0.1-0.2 pts. wt. tapioca, 5 pts. wt. calcium superphosphate, 0.05 pts. wt. slaked lime and 0.02 pts. wt. enzyme-producing microorganisms.    The base material prepared by the pile fermentation of the Cunninghamia lanceolata bark comprises 100 pts. wt. powdered bark of Cunninghamia lanceolata, 2 pts. wt. urea, 0.02 pts. wt. slaked lime and 0.01 pts. wt. wettable powder containing 95% hymexazol. The tapioca has a mesh size of 3-5 and the powdered bark of Cunninghamia lanceolata has a mesh size of 8-10.
