摘要
中国樱桃‘对樱桃’(Prunuspseudocerasus)生根试管苗移栽,直接下地成活率为0%,通过温室过渡驯化后移栽下地成活率达95%以上,这个过程中驯化移栽的空气相对湿度、温度和营养土移栽的排水因素是其成败的关键。特此做了如下试验,证明在根系发达、无污染的健壮试管苗、蛭石或蛭石+珍珠岩(体积比1:1)是最理想的过渡驯化基质、有效叶片数5片以上的条件下成活率最高达95.5%。相对空气湿度在90%到100%成活率可以稳定保持在95%以上、棚内气温为22 ̄26℃,地温15 ̄18℃,对试管苗过渡驯化效果生长最好。40d后移栽到营养土(将壤土、沙子、草炭按照体积比例为4:2:1混合)容器里,将刚栽完的营养土钵苗摆在地面上,可以快速排去积水,一般在3 ̄5d内水排去50%,苗成活率高达95%。
The survival rate of Chinese Cherry 'Duiyingtao' (Prunus pseudocerasus)tube seedling that transplant to nutritional soil directly was 0%. The successful transplantation was gained by the method that acclimate tube seedling in free soil medium in a little plastic hut in greenhouse at first transplantation, then transplant in nutritional soil. The survival rate raise to over 95%.The results show that relative air humidity, temperature in acclimatization and drainage of nutritional soil in transplantation are main factors to ensure successful transplantation. If the relative air humidity was kept 90%-100%, then more high survival rates would be attained. The fitting transplant air temperature was between 22- 26°C and the fitting medium was 15-18°C, and the fitting medium was vermiculite or vermiculite and perlite mixture in volume of 1:1. After 40 days of Accommodation, the seedlings were transplanted to nutritional soil that was made from mixture of loam, sand and peat in dispensation of 4:2:1 in volume. It can efficiently drain excess water out of pot after transplantation by putting the pots on the earth. The survival rate of transplantation was 95% when 50% excess water was drained out of pots in 3-5 days.
