Description

technical field [0001] The invention belongs to the technical field of agricultural and forestry production, and in particular relates to a production process of a matrix used in the technical process of agricultural and forestry production. Background technique [0002] Seedling substrate is an important material in the production of modern agricultural and forestry crop seedlings. It has the characteristics of high germination rate, high survival rate, strong water and fertilizer retention capacity, and good air permeability. It has broad application prospects and a huge market in modern agricultural and forestry production. [0003] Biochar refers to the high-temperature treatment of biomass under anoxic conditions. The oil and gas in the biomass are burned or collected after separation, and the remaining solid matter is mainly biochar. Biochar is almost pure carbon, and it will not disappear for hundreds to thousands of years after being buried in the ground. It is equi...
