我省水杉种源少,苗木繁殖主要靠扦插育苗.1977年以来,我场开展了水杉四季扦插育苗试验,主要技术是:一、硬枝扦插:冬末初春利用全木质枝扦插.优点是穗源丰富,年生长量大,苗高可达80—100厘米,基径0.8—1.5厘米,当年可以出圃.1.育苗地的选择和苗床制作:不同质地的土壤,空气量不同,对插穗生根的影响亦有差异:土壤与插条生根的关系:
Myeogongmicrter less provenance, nursery stock breeding rely mainly on cutting propagation. Since 1977, I carried out the field of Metasequoia cuttings cuttings of four seasons, the main technical are: First, the hardwood cuttings: early winter late spring all-wood shoot cutting advantage is Rich source, annual growth, seedling height of up to 80-100 cm, the base diameter of 0.8-1.5 cm, the year can be nursery .1 seedling selection and seedbed production: different texture of the soil, the amount of air, root cuttings The effects are also different: the relationship between soil and cuttings rooting:
