青海云杉常规播种育苗与强化播种育苗的关键技术

Conventional and accelerating sowing and seedling technology on Picea crassifolia

系统调查总结了青海云杉常规播种育苗的关键技术;并在常规育苗的基础上,参考国内外有关云杉和青海云杉的强化育苗技术,总结了青海云杉强化育苗的关键技术,包括温室塑料大棚容器育苗技术和夜间补光技术。对青海云杉常规播种育苗技术和强化播种育苗技术进行比较分析,二者的关系是常规播种育苗是青海云杉播种育苗的基础,而强化播种育苗是青海云杉播种育苗的发展方向。

The key conventional techniques of Picea crassifolia seeding and seedling cultivation in Qinghai province were summarized. On the basis of conventional seedling raising, the key technologies of strengthening seedling raising of Qinghai spruce, including greenhouse plastic greenhouse container seedling raising technology and night light replenishment technology, were summarized by referring to the strengthening seedling raising technology of spruce and Qinghai spruce at home and abroad. The relationship between conventional seeding and seedling raising technology of Qinghai spruce and intensive seeding and seedling raising technology is that conventional seeding and seedling raising is the foundation of Qinghai spruce seeding and seedling raising, while intensive seeding and seedling raising is the development direction of Qinghai spruce seeding and seedling raising.
