水杉扦插全光育苗,是林业生产技术上的一项革新。近年在我地有了较大发展。1975年春季,我们在水杉硬枝扦插开始后,利用2千根6—12厘米长的残短枝条,放在50ppm荼乙酸溶液中浸泡20小时(比长枝少4小时),趁雨后阴天在含砂70％的高厢苗床上,用2×5市寸的株行矩,进行了短枝扦插全光育苗试验,收到了良好的效果,成苗率在90％以上。通过观察,水杉春季短枝扦插全光育
Metasequoia cuttings all nursery seedlings, forestry production technology is an innovation. In recent years, I have made great progress. In the spring of 1975, after we started the hardwood cuttings of Metasequoia, we used 2 thousand residues of 6-12 cm in length and dipped in 50 ppm of tartaric acid solution for 20 hours (4 hours less than long branches) Day in 70% of the sand bed containing 70%, with 2 × 5 inch size of the plant line moment, the whole shoot nursery shoot cutting test, received good results, the rate of more than 90% of the seedlings. Through observation, Metasequoia shrubs in spring short shoots all photoperiod
