库尔勒香梨树生长期园艺修剪技术对梨火疫病的控害作用
Effect of horticultural pruning of Korla fragrant pear trees during the growth period on pear fire blight
摘要
Abstract
[Objective]To study the effect of long-term horticultural pruning technology on pear fire dis-ease control and provide some technical support for controlling the spread of pear fire disease and preventing excessive pruning.[Methods]Starting from May 11,2022,the diseased shoots of pear trees were collected every 10 days,and the phloem and woody parts were separated from the disease-health junction at 5 cm,10,15 and 20 cm away from the disease-health junction,and the presence of pathogenic bacteria was detected indoors.From May to October,pruning was carried out monthly at the junction of disease and health to ob-serve the control effect of pruning on pear fire blight in pear orchards.Starting from April 15,2022,pruning was carried out every 10 days in pear orchards at the junction of diseased shoots and health at 5,15 and 30 cm away from the junction of disease.[Results]Indoor testing found that no pathogenic bacteria could be detec-ted at 15 cm from the junction of disease and health,and pruning at the junction of disease and health from May to October reduces the number of sick trees in pear orchards from 11 to 5,and the number of infection points decreased from 17 to 9.[Conclusion]In summary,pruning from the junction of disease and health has a certain control effect on pear fire blight,but there is a phenomenon of repeated occurrence of cut pear fire blight.To prevent the recurrence of pear fire blight at the incision site,the diseased branches should be cut at least 15 cm away from the junction of the diseased and healthy.关键词
