兴安落叶松是更新造林的主要树种之一,因其生长速度快,材质优良,又是营造速生丰产林的好树种。我局过去虽然营造了大面积的人工林,由于自由式的采种和收购,种子质量低劣,苗木质量差,推迟了速生丰产的年限。要想林木速生丰产,关键是解决优良种子问题。而当前种子园处于初建时期,不能大量提供良种。在这种情况下,最好的办法是在现有的人工用材林中,选择优良林分,加以人为措施改造成为母树林。这样的母树林,结实早、产量高、质量好。是当前一个时期解决良种的有效途径。
Larix Larix reforestation is one of the main reforestation, because of its fast growth, good quality, but also to create a good fast-growing plantation tree species. In the past, despite the fact that I built a large-scale plantation in the past, due to the free-range planting and acquisition, the quality of the seed is poor and the quality of seedlings is poor, the time limit for fast-growing and high-yielding has been postponed. In order to yield fast-growing trees, the key is to solve the problem of excellent seeds. The current seed orchard was first built, can not provide a large number of varieties. In this case, the best way is to select good stands in existing timber plantations and make artificial measures to transform them into mother trees. Such mother woods, strong early, high yield, good quality. It is an effective way to solve the thoroughbred in the current period.
