通过对三倍体山杨试管苗移栽成活率进行的探讨表明,影响试管苗移栽成活率的关键因素是:①不同基质对成活率有影响,腐殖土效果最佳;②温室内的温湿度对成活率有影响,适宜的移栽温度为20 ～30 ℃,最高不超过35 ℃,最低不低于15 ℃。移栽后5d 内地温保持在22 ℃以上,湿度控制在80 % ～90 % 并有自然光照。每天需进行叶面喷雾2 次;③全年均可进行移苗,但以4 ～10 月移苗为佳,成活率可达85 % ～90 % 。虽然7 ～8 月气温高达30 ℃,成活率仍能达90 % 以上,而且生长迅速。
The study on the survival rate of triploid poplar plantlets showed that the key factors affecting survival rate of transplanted in vitro plantlets were as follows: (1) the effect of different substrates on the survival rate was the best; (2) Temperature and humidity have an impact on the survival rate, suitable transplanting temperature is 20 ~ 30 ℃, the highest does not exceed 35 ℃, the lowest not less than 15 ℃. 5d after transplanting to maintain the temperature above 22 ℃, humidity control at 80% to 90% and a natural light. The foliar spray should be carried out twice daily. ③ The whole plant can be transplanted throughout the year. However, it is better to transplant the seedlings from April to October with a survival rate of 85% -90%. Although the July ~ August temperature as high as 30 ℃, the survival rate can still reach 90% or more, and rapid growth.
