Establishing method of pinus kesiya royle ex gordon cutting and breeding system

The invention discloses an establishing method of a pinus kesiya royle ex gordon cutting and breeding system. According to the establishing method disclosed by the invention, scions of superior plants are selected as cutting propagation materials, an optimized light matrix is adopted to be matched with hormone, and nourishing-bag seedlings are utilized for carrying out rapid cultivation and seedling management, so that quick industrial breeding which is light in matrix, good in rooting, high in seedling forming rate and strong in nursery stock is realized, the breeding cost is reduced, the breeding efficiency is increased, and meanwhile, forestation and transportation cost and labor intensity are reduced. Short and dry type stock plants of the pinus kesiya royle ex gordon produce 200 to 300 scions per plant, the weight of light-matrix nourishing-bag seedlings is 0.14 to 0.15 kg per bag when the seedlings are out of a nursery, the rooting time after cutting is 10 to 15 days ahead, the average seedling height i
