青海云杉强化育苗技术试验

Test on Techniques of Accelerating Spruce seedling Growth

东峡林场多年来围绕云杉生长的主导因子开展了云杉强化育苗技术试验,在常规的日光温室塑料大棚容器育苗技术基础上,通过人为调控云杉生长发育所需的水、肥、热、光等环境因子,促进苗木生长,为缩短育苗周期提供了可靠的依据。

Tests on factor effect spruce growth were conducted in Dongxia Forestry Centre, based on the container seedling cultivation technique in green house, the environment factors as water,fertilizer,heat,light were controlled artifical in order to promote the growth of seedling and the seedling periodic shortened.
