[目的]探索金银花植株夏季凋萎的原因及解决对策。[方法]采用实地抽样方法调查土壤养分含量、金银花品种、树龄、病虫发生程度、季节对金银花夏季凋萎枯枝率的影响,并通过凋萎防控试验提出夏季凋萎的防控对策。[结果]随着土壤中有机质含量升高,金银花夏季凋萎枯枝率降低;毛花柱忍冬的夏季植株凋萎枯枝率最高,其次为华南忍冬,红腺忍冬夏季植株凋萎枯枝率最低;金银花植株夏季凋萎枯枝率与白粉病病情指数相关性达显著水平;各季节金银花植株凋萎枯枝率从高到低排列是夏、秋、冬、春,其中毛花柱忍冬夏季凋萎枯枝率高达97.95%。[结论]在调查分析金银花植株夏季凋萎症状表现、发生原因的基础上,提出了种植抗病力强的品种;开花前和采花后及时使用低毒药剂防治蚜虫、金银花尺蠖和白粉病;采花后及时剪除枯枝和老弱枝条;秋、冬季采用有机肥与三元复合肥配施等防控植株夏季凋萎的对策。
[Objective] The research aimed to explore the causes of summer honeysuckle plants wilting and countermeasures. [Method] The effects of soil nutrient content, honeysuckle variety, tree age, degree of occurrence of pests and diseases, seasons on the rate of summer withered and withered branches in summer were investigated by field sampling method. The prevention and control measures of summer wilting were proposed by wilt prevention and control experiment. [Result] With the increase of organic matter content in soil, the rate of withered branches decreased in summer, while the rate of withered branches in summer was the highest in honeysuckle, followed by the honeysuckle in southern China. . The correlation between the rate of withered branches and the disease index of powdery mildew was significant in the honeysuckle plants. The highest rate of withered branches was in summer, autumn, winter and spring in each season. Lost rate as high as 97.95%. [Conclusion] Based on the investigation and analysis of the manifestations and the causes of summer wilt symptoms in honeysuckle plants, the paper put forward the plan of planting the varieties with strong disease resistance, using low toxicity medicaments to control aphids, honeysuckle scales and powdery mildew before flowering and after flowering, After the timely removal of dead branches and old and weak branches; autumn and winter with organic fertilizer and ternary compound fertilizer and other control plants in summer wilting countermeasures.
