水杉、池杉、落羽杉（以下简称“三杉”）,具有生长迅速,干形圆满、通直,材质良好,适应性强,树冠小,病虫害少等特点。其中池杉、落羽杉还具有耐水湿、耐干旱、易萌芽,便于更新等优点,所以,深受群众欢迎。目前已在我省大江南北平原水网地区广为引种栽培。 我场于1971年开始引进少量“三杉”种子过引繁殖,取得了成功。但因种源缺乏,所以扦插繁殖就成为我场发展“三杉”的重要途径。当前,已广泛应用的是春季硬枝扦插和夏季嫩枝扦插。 现将我场甘泉工区近几年来“三杉”扦插繁殖技术总结如下:
Metasequoia, Ipomoea, Taxodium distichum (hereinafter referred to as “fir”), with rapid growth, stem-shaped successful, straight, good material, adaptability, small crown, pest less. One of Ikeda, Taxodium also has water-resistant wet, drought-resistant, easy to sprout, easy to update, etc. Therefore, by the masses. At present, it has been widely introduced and cultivated in the water network area of the Yangtze River in our province. My field in 1971 began to introduce a small amount of “fir” seeds over breeding, and achieved success. However, due to the lack of provenance, cutting propagation has become an important way for us to develop “San-fir.” At present, it has been widely used in spring hardwood cutting and summer softwood cutting. Now my field Oasis area work in recent years, “three fir” cutting propagation techniques are summarized as follows:
