都山绣球组培苗露地栽培研究

Study on tissue culture seedlings cultivation in open field of Hydrangea bretschneideri Dipp. Var dushanensis

通过对都山绣球组培苗移栽1年后进行露地栽培,研究不同土壤、不同海拔、不同光照、不同管理条件下苗木的生长情况。结果表明,将苗移栽到河北宽城都山、塌山及以北的承德县和承德市均能正常生长,且自然条件下能安全越冬;该苗木适合承德市中南部地区栽植;在壤质土上成活率高,生长快;不同海拔对其生长影响不大;移栽时只浇1次水,以后在自然条件下生长的苗木成活率较低,生长速度较慢;移栽后按园林苗木花卉进行管理的成活率高,生长快;移栽后在太阳直射光下生长的成活率较低,生长较慢,而在半阴半阳（50%-60%日照）处移栽的苗木成活率高,生长快。

In order to observe the seedling＇ s growth condition in diffident environment, we cultivated the tissue culture seedlings which had been transplanted for one year in open fields. The results show that It grows well and can survive in winter in Dushan mountain, Tashan mountain, Chengde county and Chengde cit. The middle-south of Chengde area is suitable for its growth. The survival rate is higher and it grows faster in loam soil. Different altitudes have little effect on its growth. If watered just one time after transplanting, the seedlings are hard to survive in nature environment, or grow very slowly. If watered more times, it can grow better. The survive rate will increase and it grows more fast when planted in the half shade （sunshine 50% - 60%） area.
