| 国土绿化对树种的需求呈多元化趋势。今后我国国土绿化的主战场是西部和北部地区，造林地多以宜林荒山荒地荒滩、荒废和受损山体、退化林地草地等为主，对乡土树种和耐瘠薄、耐盐碱、抗寒、抗旱、抗风等逆性强的树种需求依然较大。 The demand for tree species for land greening shows a diversified trend. In the future, the main battlefield of China's land greening will be the western and northern regions. Most of the afforestation land will be suitable for afforestation, such as barren mountains, wasteland, wasteland and beaches, abandoned and damaged mountains, degraded woodland and grassland, and there will be a great demand for local trees and trees with strong stress resistance such as barren, salt and alkali resistance, cold resistance, drought resistance and wind resistance. 南部、东部、中部地区在巩固现有绿化成果基础上，以调结构、提质量为主，森林质量精准提升、国家储备林基地建设等工程项目的持续推进，对珍贵树种和特色经济林树种苗木有一定需求。城乡绿化美化及新农村建设，对新优乡土树种苗木、彩叶树种苗木及花灌木有一定需求，但由于受绿化用地、市政项目压缩等因素的制约，同质化中小规格苗、常州苗木 保定电动门 保定空压机 化粪池模具 微型蠕动泵 保定强夯 收费岛模具规绿化苗木和进口高端大树苗需求量将会大幅下降。 On the basis of consolidating the existing greening achievements, the southern, Eastern and central regions focus on adjusting structure and improving quality, and the continuous promotion of engineering projects such as the accurate improvement of forest quality and the construction of national reserve forest base have a certain demand for precious tree species and seedlings of characteristic economic forest species. Urban and rural greening and beautification and new rural construction have a certain demand for new and excellent native tree seedlings, color leaf tree seedlings and flowering shrubs. However, due to the constraints of greening land, municipal project compression and other factors, the demand for homogenized small and medium-sized seedlings, conventional greening seedlings and imported high-end tree seedlings will decline significantly. |
