植物生长调节剂对牡丹微型盆栽春节催花的影响

为探讨植物生长调节剂复硝酚钠和芸苔素对牡丹微型盆栽春节催花的影响，选择牡丹品种‘紫二乔’，用复硝酚钠、芸苔素、复硝酚钠和芸苔素混合溶液分别进行灌根和喷施处理，观察测定‘紫二乔’的催花物候期、生长发育情况。结果表明：98%复硝酚钠5000倍喷施处理能够显著提高‘紫二乔’春节催花过程中的开花质量和缩短催花时间，建议在牡丹品种‘紫二乔’微型盆栽春节催花过程中使用复硝酚钠进行喷施处理。

Effects of plant growth regulators on Peony Miniature Potted Plants for Spring Festival Flower Forcing

In order to investigate the effects of compound sodium nitrophenolate and brassin on the flowering of peony miniature potted plants in spring, we selected peony variety ''Zi Er Qiao'' and applied compound sodium nitrophenolate, brassin and a mixture of compound sodium nitrophenolate and brassin by root irrigation and spraying respectively, The flowering phenology, growth, and development of ''Zi Er Qiao'' were observed and measured. The results showed that spraying 98% compound sodium nitrophenolate 5000 times can significantly improve the flowering quality and shorten the flowering time during the Spring Festival flowering process of ''Zi Er Qiao''. It is recommended to use compound sodium nitrophenolate for spraying during the Spring Festival flower forcing of ''Zi Er Qiao'' miniature pot peony variety.
