云杉是我省林区的主要更新树种,过去由于种子不足,直接影响育苗、造林的速度。母树林是种子遗传品质经过一定改良的专供采种的林分,它是种子园未大面积建成以前,解决林木种子的过渡形式。建立母树林,能提高种子的产量和品质,对加速绿化祖国,提高林木生产有着十分重要的作用。 Spruce is the main regeneration species in our province’s forest area. In the past, due to the lack of seeds, the spruce directly affected the speed of nursery and afforestation. The mother forest is the seed genetic quality after a certain improvement for the purpose of planting the forest, it is the seed orchard before the completion of large areas to solve the transition form of tree seeds. Establishing mother trees can increase the yield and quality of seeds and play an important role in accelerating the afforestation of the motherland and raising the production of trees.
