近年来,组织培养在各地已蓬勃开展起来,许多植物都可利用组织培养技术来进行快速繁殖,但试管苗的移栽一直未得到很好的解决。由于试管苗是在一个无菌的、光照、温度恒定、湿度饱和的环境条件下生长的,而土壤则是一个有菌的,条件不稳定的环境,要实现这两个环境的的转移,需要一个过渡,使试管苗逐步得到锻炼,无土栽培则能提 In recent years, tissue culture has been vigorously carried out in various places, many plants can use tissue culture techniques for rapid breeding, but the transplant of plantlets has not been well resolved. Because plantlets are grown in a sterile, light, constant temperature and humidity-saturated environment, the soil is a bacteria-free, unstable environment and the transfer of these two environments requires A transition, so that test tube seedlings gradually get exercise, soilless culture can mention
