大花天竺葵嫁接技术研究
Study of Grafting Technique of Pelargonium damesticum Bailey
摘要:
为了提高大花天竺葵观赏性，在同一株上嫁接不同花色枝条，研究了不同嫁接方法、砧穗组合和嫁接时期对嫁接成活率、新枝长度、新枝粗度和花枝率的影响。结果表明：大花天竺葵3月中旬采用劈接嫁接成活率、生长量和花枝率较高，不同花色砧穗组合嫁接成活率 > 93%、新枝长度 > 24 cm、新枝粗度 > 6 mm、花枝率 > 25%。建议大花天竺葵3月中旬采用劈接来提高嫁接成活率、生长量和开花数。
Abstract:
In order to improve ornament of Pelargonium damesticum Bailey, the effects of different grafting method, stion and period on survival rate, branch length, branch diameter and flowering branch rate were studied. The results showed that the survival rate, growth and flowering branch rate of Pelargonium damesticum Bailey were higher, which was grafted with cleft grafting in the middle of March, the different color flower stion’s survival rate > 93%, branch length > 24 cm, branch diameter > 6 mm, flowering branch rate > 25%. Pelargonium damesticum Bailey should be grafted with cleft grafting in the middle of March to increase survival rate, growth and number of flower.
