我区的东岭、增盛两个林场,被省确定为重点樟子松母树林发展基地,面积为2.1万亩。现已进入结实能力的有1000亩,10—15年生的有8000亩,其余绝大部分是幼龄阶段。这两处营造的樟子松初期以防风固沙为主,所以造林密度较大。按母树林要求,今后需要疏伐、改造、加强管理等,以提高种子的产量和质量,培育出适宜我区自然条件的优良种子。 My district Dongling, Zeng Sheng two farms, the province identified as the focus of Scotch Pine growing base, an area of ​​21000 acres. Has now entered a solid capacity of 1000 acres, 10-15 years of 8000 acres, most of the remaining young stage. The two constructions of Pinus sylvestris were mainly windbreak and sand-fixation, so the planting density was larger. According to the requirements of the mother forest, in the future there will be a need to thin out, transform and strengthen management so as to increase the yield and quality of the seeds and cultivate fine seeds suitable for the natural conditions in our region.
