Cultivation and Application of Hemlock Phenology and Disaster Spectrum in Bailongjiang Forest Area of Gansu Province
As a native tree species in Bailong River basin of Gansu province,hemlock is an excellent tree species for afforestation and water conservation forests in barren mountains with developed roots,resistance to wind and snow pressure,and long life.However,due to its small population in distribution area,low seed germination rate,long dormant period and poor natural regeneration ability,hem-lock seedling cultivation technology is very important.Through the cultivation of hemlock seedlings in the state-owned nursery of Eco-logical Construction Management and Protection Center of Gansu Province,the phenological characteristics and disaster laws were re-corded in detail,and the technology of seed collection and seed production,seeding and seedling cultivation,container seedling trans-plantation and cultivation,artificial afforestation and other technologies were further understood and mastered,which could provide ref-erence for the cultivation of hemlock.
