喷施抗寒剂对三角梅抗寒性的影响

Effects of Spraying Cold-resistant Agent on Cold Resistance of Bougainvillea

为使三角梅在非适宜种植区大量露地栽培,分别对6个三角梅品种的枝叶涂抹抗寒剂(5%保湿剂、5%粘合剂、1.0 g/L氯化钙、0.30%磷酸二氢钾、100 mg/L水杨酸混合)进行2次抗寒处理。结果表明:适宜引种的品种为加州黄金和斑叶安格斯,低温胁迫对两者的影响相对较小,抗寒剂对其起到了一定的作用;洒金叶玫红适合引种,但要对其进行抗寒处理,抗寒剂可明显提高其抗寒力。

In order to make a large amount of open cultivar in the unsuitable planting area,the six varieties of Bougainvillea applied anti-cold agent(5%humectant,5%binder,1.0 g/L calcium chloride(CaCl2),0.30%potassium dihydrogen phos?phate(KH2 PO4),100 mg/L salicylic acid(SA)mixed)were subjected to two cold treatments.The results showed that Califor?nia gold and zebra Angus were suitable for introduction,and the low temperature stress had relatively little effect on the two,and the cold-resistant agent played a certain role.Sprinkle gold leaf rose red was suitable for introduction but it should be treated with cold resistance,and cold-resistant agent could significantly improve its cold resistance。
