Abstract: At present, the domestic cost of resin-tapping is increasing, the price of rosin fluctuates frequently and is relatively low, which causes low economic benefit of resin-tapping. Especially for decentralized rosin farmers, since the benefits cannot offset the loss of the wood for tapping and the cost of resin-tapping, farmers’ willingness for resin-tapping is not high, and the resin industry is facing the problem of raw material shortage. But the price rise in the domestic market will weaken the position of Chinese rosin products in the international market and lead to a dramatic increase of international rosin products, which will induce the replacement of rosin products by petroleum resins. In this review, technologies of variety breeding, ecological influence, tree factor, tapping methods, plant density, soil factor and so on in China are summarized, in order to provide certain theoretical reference for developing new technology of Pinus massoniana tapping and improving business management system of high-yield Pinus massoniana plantations, give technical guidance for the resin-tapping farmers, and find a solution to the problem of high cost and raw material shortage in resin industry.
