水杉是世界稀有珍贵树种。我场地处平原湖区,栽植的水杉适应性强,生长快,树形高大,材性好,深受群众喜爱。10年生的水杉高10多米,胸径26厘米。多年来,我们一直采用扦插育苗。并且,由春插转为以深秋插为主。实践告诉我们,深秋扦插育苗具有很多好处,如:插条来源广,可大面积育苗,成本低;单位面积扦插密度大,成活率高,相应产苗量高;气温适宜,管理集中方便;利于移栽养大苗。故我们从1976年以来,每年打插面积在5—10亩之间,产苗几
Metasequoia is rare in the world of precious species. My field is located in plain Lake District, planted Metasequoia adaptable, fast growth, tall tree, good material, loved by the masses. 10-year-old Metasequoia higher than 10 meters, diameter 26 cm. Over the years, we have been using cuttage nursery. And, by the spring inserted into late autumn inserted mainly. Practice tells us that the late autumn cutting seedlings have many benefits, such as: broad source of cuttings, large areas of seedlings, low cost; density per unit area of the large, high survival rate, the corresponding seedling production; suitable temperature, centralized management convenience; Transplanting raised seedlings. Therefore, since 1976, we have inserted an area of between 5 and 10 mu each year, producing a few seedlings
