Abstract

Spruce is an important timber tree species for industrial use .The bottleneck for the cultivation of spruce is its slow growth , which affects the genetic evaluation process seriously .The domestic and overseas researches on accelerating spruce seedling growth by plastic sheds and greenhouses were expatiated .And the factors influencing fast growth of spruce seedlings such as light , temperature , humidity , moisture and fertilizers were analyzed . Increasing illumination had a significant effect on the growth of spruce seedlings .Light treatment could hinder from early dormancy of spruce .Temperature in the roots was also an important factor affecting spruce growth .The techniques for accelerating seedling growth could shorten the period of seedlings cultivation .Finally , further study in future was also put forward .[ Ch , 34 ref .]
