按树的无性繁殖通常采用组织培养法和扦插法。由于组培苗工厂投资大,技术要求高,生产苗木的成本高,因而组织培养法较难适应当前的林业生产需要。扦插育苗虽然育苗材料来源广,繁殖系数大,育苗设备简单,生产成本低及遗传性比较稳定,但难于解决扦插苗的病害问题。因为采用土壤等固体的基质扦插, Asexual tree-based propagation usually adopts tissue culture and cuttings. Due to the large investment in tissue culture seedlings plant, high technical requirements, the high cost of producing seedlings, tissue culture method is difficult to adapt to the current forestry production needs. Although cutting seedling nursery material source wide, multiplication coefficient, nursery equipment is simple, low production costs and genetic stability, but difficult to solve the disease of cutting seedlings. Because of the use of solids such as soil matrix cutting,
