水杉育苗多采用遮荫的办法,以调节温度,保持湿度,提高扦插成活率,通常要用大量的木桩和苇箔,而且每天还要揭盖荫棚,因此,大面积生产有一定困难。为了寻找省工、省料、管理简便的育苗方法,1976年我们进行了全光与覆盖遮荫(前期用塑料薄膜,后期用杨树枝叶遮荫)的对比试验。在全光育苗试验中,又安排了不同作床方式、 Metasequoia nursery use shading approach to adjust the temperature and humidity to improve the survival rate of cuttings, usually with a large number of wood piles and reed foil, but also cover the shelter shade, therefore, large-scale production has some difficulties. In 1976, we conducted a comparative test of total light and covered shading (pre-use of plastic film and later use of poplar branches and shades) in order to find ways to save labor, save materials and manage easily. In the whole light nursery test, and arranged for different ways for the bed,
