刺槐是优良的绿化造林树种.苏北平原地区由于普遍大量选用刺槐绿化造林,使林业事业获得迅速发展,在改善生态环境,巩固河提,保持水土,解决用材,提供薪柴,广辟肥源、饲料和蜜源,发展养蜂等方面都起到了很大作用.为了给刺槐造林提供良种,充分发挥刺槐的多种功能和效益,我所自1978年起进行了刺槐良种选育,现已取得较为显著的效果.具体有以下几个方面:一、广泛搜集刺槐基因资源,初步建立了刺槐基因库.本所现有优良单株92个,国外种源13个,为深入进行刺槐遗传改良试验研究奠定了一定的基础.二、初步筛选出了适合江苏栽植的石林、箭杆、射10、射12等刺槐优良无性系.经多点栽植试验,这些无性系表现出许多优良性状.主要是:1.干形通直,圆满,粗细均匀,尖削度小,林相整齐美观.
Robinia pseudoacacia is an excellent green afforestation tree species in the northern Jiangsu Plain due to the widespread selection of acacia afforestation afforestation, the rapid development of forestry, in improving the ecological environment, consolidate the river to maintain water and soil, to solve the timber, to provide fuelwood, , Feed and nectar, the development of beekeeping and other aspects have played a significant role.In order to provide good varieties of acacia afforestation, give full play to a variety of functions and benefits of acacia, I have been since 1978, the acacia seed breeding has been made More specific results are as follows: First, a broad collection of locust gene resources, the initial establishment of the locust gene pool.Excellent existing 92 plants, 13 foreign provenances, in-depth genetic improvement trials of locust And laid a solid foundation for the research.Secondly, the clones suitable for planting acacia, arrowhead, shoot 10, shoot 12 and other fine clones were initially screened out.These clones showed many excellent traits after many planting experiments : 1. Dry shape straight, successful, uniform thickness, sharp taper, neat forest appearance.
