1. Pinus bungeana seedlings belong to the national second-class cherished and protected plants, and are also precious tree species in short supply in China (the national forestry department has long strictly protected them, and relevant tree materials have also been recorded). The relationship between market supply and demand directly affects the price of Pinus bungeana seedlings. For example, the price of Pinus bungeana seedlings over 3m in Beijing market is 3,000 yuan/plant. Since 2000, the price has been very high, and the more speculation, the higher. This aspect is particularly obvious, followed by the increasing demand in Beijing, Tianjin, Hebei, Shandong, Shanghai, Zhejiang, Jiangsu, Hangzhou, Hefei, Dalian and other places, which has also driven the price of this seedling to rise.
Second, the morphological characteristics give Pinus bungeana seedlings a larger market space. There are many deciduous trees and few evergreen trees in China, and the demand for evergreen trees is large. Pinus bungeana is simple, vigorous and graceful, with a tower-shaped crown, majestic and tall, and evergreen all the year round. It is an indispensable first choice tree species in the garden, which can be clustered and planted alone in the green space, and can also be used as street trees and scenic spots for greening. For example, Pinus bungeana is used in the greening of Chang 'an Avenue in Beijing to set off the majesty of the capital.
Third, the growth habit and adaptability to the natural environment are conducive to the market convergence of this variety. Pinus bungeana is a slow-growing plant with slow growth rate, long growth cycle and relatively high price. Pinus bungeana has strong environmental adaptability, likes light and shade, is ridge-tolerant, more salt-alkali tolerant, has low requirements on soil, can adapt to soil PH value of 7.5-8, is resistant to drought and strong wind, has few pests and diseases, and has low management cost. Moreover, the tree species has strong resistance to sulfur dioxide, hydrogen fluoride pollutants and smoke dust in the air, and can grow at a temperature of 40 degrees and a low temperature of -40 degrees, so it can be successfully introduced to Beijing, Tianjin, Hebei, Shanghai, Shandong, Liaoning, Zhejiang, Jiangsu, Hangzhou, Hefei, Dalian and other cities. Suitable for planting in northern and southern cities of China.
Fourthly, there are few sources of Pinus bungeana seedling breeding resources, and the requirements of the project give this seedling great value-added potential. Pinus bungeana has natural forest distribution groups in Shanxi, Henan, Shaanxi and southern Gansu, with a small number and scarce and precious materials. Its seedling can only be divided into two types: planting with plants and sowing with seeds. In a certain period of time, the quantity is small, the price will not plummet, and nursery breeding is still profitable. Pinus bungeana has become a "big tree" in landscape engineering. After nursery cultivation, repeated transplanting and root cutting, the fibrous roots are developed, the soil balls are dense, the roots are less damaged after transplanting, and the survival rate is high. The landscape planning and design in the new era requires the diversity of tree species, which also makes Pinus bungeana seedlings a special variety, which is widely used and constitutes a part of the price factor. Conclusion: As a new industry, the nursery stock industry should choose the best one for production, scientific management and improve the quality by using new technology according to years of production and marketing experience and its own advantages. Grasping the information of seedlings and attaching importance to market research should not be driven by high profits, which violates market rules and hinders the healthy development of seedling wood industry.
