一、概况:1976年开始试建杉木初级种子园,1984年重新调整,现经营面积1924亩,分为两个生产点,大坪种子生产区和种子园育种试验区,两个区相距3公里,这样有效的防止了不良花粉的侵入,其中种子生产区1000亩,生产初级良种近400kg,育种区200亩,试验区400亩,母树林478亩,生产种子500多kg.二、种子园的建设:①杉木:宜宾地区在80年代初收集了约500个全国各省区优良无性系,通过表型选择约100个特别优良的无性系已移植到富顺种子园.通过10年表型选择和子代测定,初步选出11个表现优良的无性系.马尾松:1984年收集了全省优树400个,并且进行了部分子代测定.选择了大头茶作为营建混交林的主要伴生树种,拟在种子园建设后期,营建
First, an overview: Beginning in 1976 to test the establishment of Chinese fir primary seedling, re-adjusted in 1984, now operating area of 1924 acres, is divided into two production points, Daping seed production and seed breeding test area, the two districts apart 3 km, This effectively prevents the intrusion of undesirable pollen, of which 1,000 acres of seed production area, the production of primary seed nearly 400kg, breeding area of 200 mu, 400 mu of test area, the mother of the forest 478 acres, more than 500 kg of seed production. : ① Chinese fir: Yibin collected about 500 excellent clones from all provinces and regions in the early 1980s and selected about 100 excellent clones by transplanting to Fushun Seed Orchard. By 10-year phenotypic selection and offspring assay , Eleven clones with good performance were initially selected.Mononetus: 400 elite trees were collected from the province in 1984, and some offspring were selected.And the main associated trees were selected for the construction of mixed forest, Park construction late, construction
