摘  要:
在自然越冬条件下,以一年生金叶女贞扦插苗为试材,采用冬前田间喷施及喷施+灌根试验,应用质膜透性-电导法测定金叶女贞苗木抗寒生理指标的变化,研究纯天然植物生长调节剂爱密挺各浓度梯度在不同应用时期、不同施用方法对金叶女贞苗木抗寒性及越冬成活率的影响。结果表明:应用植物生长调节剂爱密挺增强金叶女贞抗寒性的最佳施用时期为冬前1个月,最佳浓度为100mg·kg-1,最佳施用方法是单纯灌根。

摘  要:
The cold resistence physioloigical indexes of the leaves with one-year of Ligusthum introduced to Lanzhou Botanical Garden were measured and compared,in the condition of nature overwintering, by field spraying before winter and root irrigation test,and application of membrane permeability determination.Effect of pure natural plant growth regulator love in the concentration gradient in different period and different application methods on seedling cold resistance of Ligusthum and overwintering survival was studied. The results showed that the best period was for irrigation water before twenty days of winter, optimum concentration was 100 mg·kg-1, optimum application method was root irrigation.
