摘要
充分利用落叶松种间杂种优势,并把它作为落叶松遗传改良的基本策略,这在我国北方的林业工作者中已逐渐成为共识,但如何大量生产杂种种子一直是杂种落叶松推广技术中的瓶颈。本文根据长期的研究结果,提出了大量生产优良杂种种子的可靠方法,它符合低投入、高产出、易普及的原则。
Taking use of hybridization advantage between species of Larix is regarded as the basic
strategy of genetic improvement of Larix, which have been become common idea by forestry
researcher in the north of China. But how to produce largely hybrid seeds always is the bottleneck of
application techniques for hybrid seed of Larix. This paper gives feasible method to produce largely
hybrid seeds on the base of long research that is low cost, high yield and easy applying.
