摘要
对陕西省己建成的油松良种基地现实良种生产数量和质量分析结果表明,良种的遗传品质和播种品质基本上达到了营建初级种子园的目的,但基地生产能力较低,良种数量远远满足不了造林用种的需要。并对加强良种基地管理,提高良种生产能力提出了一些看法。
Analysis of quantity and quality of Chinese pine seed production in the bases of Shaanxi shows that the quality in genetic and sowing of superior seeds reaches the goal of elementary seed orchard construction,but with a low production capacity,which does not meet the demands of seeds in afforestation.Some suggestion to intensively manage seed multiplication bases and enhance seed production capacity are also proposed.
