杉木为我国特产的重要用材树种之一,具有生长快,材质好的优点,因此对杉木的培育、利用研究,历来很重视。解放后,杉木造林在我省有了新的发展,特别是经过无产阶级文化大革命以来,发展更快。苏北灌溉总渠阜宁段的河堤上,于一九六六年开始引种杉木,目前造林面积已发展到1200多亩,郁闭成林,有的林木已高达10米以上,生长很好,对我省多快好省发展用材林提供了宝贵的经验。为了杉木扩栽造林,近年来,我们在探索杉木在苏北河堤的生长特性和生态条件的同时,在总渠河堤上,选择有代表性的不同树龄的杉木1 -4株,作了杉木根系的初步观察分析,根据所取得的资料整理小结,供参考,并希同志们指正。
Cunninghamia lanceolata is one of the important timber species in our country. It has the advantages of fast growth and good material quality. Therefore, the research on the cultivation and utilization of Cunninghamia lanceolata has always attached great importance. After the liberation, the reforestation of afforestation in our province has a new development in our province, especially after the Great Proletarian Cultural Revolution, the development is faster. In 1966, the introduction of Chinese fir was started on the embankment of the Funing section of Northern Jiangsu irrigation canal. At present, the area of afforestation has developed to more than 1,200 mu. The forest is closed and some trees are up to 10 meters high and grow well. , Which provided valuable experience for the development of timber forests in our province. In order to expand afforestation of Chinese fir plantation, in recent years, we explored the growth characteristics and ecological conditions of Chinese fir plantation on the northern bank of the embankment, and selected 1 to 4 representative Chinese fir plantations Preliminary observation and analysis of the root system of Chinese fir, according to the information obtained to collate the summary, for reference, and hope comrades correct.
