檫树生长快,材质好,是我国珍贵的优良用材树种之一。檫树原产山区,寿命可达百年以上,天然林多呈散生状态。解放后,特别是1965年以来,我省各地营造了大面积的人工纯林,由于以往对檫树的生态特性和生长发育规律缺乏足够的认识,致使部分林木生长不良,成林不成材或单位面积产量不高。怎样提高檫树造林效果,为国家提供更多更好的檫树大径材?是近几年来林业生产和科研部门所注意的问题,并进行了多种方式的试验,目前看来带状林生长很好。为了总结这方面的经验,我们在湘中地区选择有代表性的地方,进行了调查。
檫 tree grow fast, good material, is one of China’s precious wood species. Sassafras tree origin mountains, life expectancy of up to a hundred years or more, mostly natural forest scattered status. After the liberation, especially since 1965, a large area of artificial pure forest has been built around our province. Due to the lack of adequate understanding of the ecological characteristics and growth and development rules of poplar in the past, some trees are poorly grown, Area yield is not high. How to improve the effect of the plantation of the plantation tree and provide the country with more and better plantation tree material? It is a problem that the forestry production and scientific research department paid attention to in recent years, and conducted many kinds of tests. Grow well. In order to summarize this experience, we have chosen representative areas in the Central Hunan Province and conducted investigations.
