摘要
经过40多a的林木良种基地建设研究,系统地总结出一套科学、完整的良种基地建设技术体系,并针对林木良种基地建设取得的经验和发展中的问题进行了深入剖析,提出了林木良种建设中的关键技术和林木良种基地建设进程图。到2010年底,共建设林木良种基地80处,面积7 535 hm2,其中包括种子园967 hm2,年产种子5.74万kg、母树林4 612 hm2,年产种子20万kg、采穗圃874 hm2,年采穗条3453万条、测定林159 hm2、优树收集圃395 hm2,展示林358 hm2,其它170 hm2。林木良种144个,木材增益为39.3%以上,果品增益达43.6%以上。
A set of scientific and integrated construction system for thoroughbred base was summed up after 40 years of studies on the construction of forest thoroughbred base in Liaoning Province. And some acquired experiences and existing problems were discussed in detail. The key techniques and process graph of the construction of forest thoroughbred were put forward. By the end of 2009, 80 forest thoroughbred bases with an area of 7 535 hm2 had been built, among which there were 967 hm2 of seed orchard with an annual seed yidd of 57 400 kg, 4 612 hm2 of parent trees with an annual output of 200 000 kg, 874 hm2 of seed orchard with annual cutting yield of 34.53 million individuals, 159 hm2 of test plantation, 395 hm2 of tree plus nursery, 358 hm2 of demonstration forest, and 170 hm2 of other forests. A total of 144 forest tree fine varieties were obtained, with wood gain of more than 39.3% and fruit gain of over 43.6%.
