水杉(Metasequoia glyptostroboidesHu et Cheng),是杉科水杉属中幸存的一种,属国家一级保护树种。近年来,我省广泛进行了人工栽培,尤以洞庭湖区各县大量发展,并表现出生长速度快,干形通直,尖削度小,出材量大的优势。为了进一步推广和发展这一珍贵速生用材树种,1978年冬,我们选择地处高丘地带的田坪水库周围,作试验林栽培了1.13万株,目前生长旺盛,成材在望. Metasequoia glyptostroboides Hu et Cheng is one of the surviving species of Metasequoia in Cirsium, which belongs to the national first-class protected species. In recent years, extensive cultivation has been carried out in our province, especially in the counties in the Dongting Lake area. It has also shown the advantages of fast growth, straight stem, sharp taper and large output. In order to further popularize and develop this precious and quick-growing timber species, in the winter of 1978, we chose to plant 11,300 experimental forests in the Pingtung Reservoir in the high hill area. At present, we are experiencing vigorous growth and looking promising.
