不同措施对银杏枯黄的防治效率的研究

为了缓解异常温度和降水量对银杏枯黄的影响，做了多种措施降低银杏枯黄比率。试验结果表明：施加液态肥可降低银杏枯黄70.76%；覆盖基质可降低银杏枯黄60.51%；喷施抑制蒸腾剂可降低银杏枯黄58.52%；喷水可降低银杏枯黄40.22%。由此可见施加液态肥预防银杏枯黄效果最佳，其次是覆盖基质，再次是喷施抑制蒸腾剂、最后是喷水。通过综合措施，达到的60%~80%预防和防治效果已经取得了相当显著的成效。

Study on Control Efficiency of Different Measures on Ginkgo biloba

In order to alleviate the influence of abnormal temperature and precipitation on withering and yellowing rate of Ginkgo biloba, various measures were taken to reduce the withering and yellowing rate of Ginkgo biloba. The results showed that applying liquid fertilizer could reduce withering and yellowing rate of Ginkgo biloba by 70.76%; covering of substrate could reduce the withering and yellowing rate by 60.51%; spraying transpiration inhibitor could reduce the withering and yellowing rate by 58.52%; spraying water could reduce withering and yellowing rate by 40.22%. So liquid fertilizer has the best effect on preventing the withering and yellowing of Ginkgo biloba, followed by mulching substrate, spraying transpiration inhibitor and spraying water had lowerest effect. Through comprehensive measures, the prevention effects could reach 60%~80%.
