摘要
开展青海云杉天然母树林培育技术研究。在母树林内设置标准地采取抚育采伐、施肥等综合措施,测定种子产量、千粒重,计算结实率、发芽率。结果表明采取抚育措施增产明显,应设置母树林基地,实现云杉种子良种化。
To research the breeding technology of natural mother forest of Picea crassifolia in Qinghai Province.Comprehensive measures such as breeding cutting and fertilization were set up in the mother trees to measure seed yield and 1 000-grain weight,calculate seed setting rate and germination rate.Adopting tending measures to increase production.The mother forest base should be set up to realize the improved variety of P.crassifolia.
