- 摘要:
- 温度和光照是影响嫁接成活的重要环境因子，西瓜嫁接愈合过程分为0～3、4～6、7～8 d 3个阶段，不同愈合阶段下温度和光照的精细化管理目前尚不明晰。该试验以“早佳84-24” 西瓜接穗为试材，以2个与接穗亲和性好的葫芦和南瓜为砧木，研究了西瓜嫁接苗愈合期间2个温度和3个光照组合处理对嫁接苗成活、生长和种苗质量的影响。结果表明：在嫁接后0～3 d温度为28℃/23℃，4～6 d温度为25℃/20℃，7～8 d温度为23℃/18℃，光照处理0～3 d为75 μmol?m-2?s-1，4～6 d 为150 μmol?m-2?s-1，7～8 d为225 μmol?m-2?s-1时西瓜嫁接苗成活率最高，且幼苗质量最佳，是适合西瓜嫁接苗愈合管理的温度和光照参数。
- Abstract:
- The temperature and light are key environment factors for the healing of grafted seedlings.The healing period of grafted watermelon seedling can be divided into three stages (0-3 d，4-6 d，7-8 d)，the precise management of temperature and light during healing period is not clear.With‘Zaojia 84-24’as watermelon scion as test materials，two high affinity grafting of calabash and pumpking as stock，the effect of two temperature and three light intensity combination treatments during the healing period on the growth of grafted watermelon seedlings was investigated.The results showed that when the temperature treatment was 28℃/23℃（0-3 d），25℃/20℃（4-6 d），23℃/18℃（7-8 d），and the light intensity treatment was 75 μmol?m-2?s-1（0-3 d），150 μmol?m-2?s-1（4-6 d），225 μmol?m-2?s-1（7-8 d）after grafting，the grafted watermelon seedlings showed the highest survival rate and the best seedling quality，indicating that this kind of temperature and light combination was suitable for healing management of grafted watermelon seedlings.
