| 摘要: |
| 1979—1983年对苹果炭疽病侵染规律、发病规律进行了系统调查研究,在此基础上探索了新的防治途径。利用常规化学保护性杀菌剂(波尔多液、退菌特等)提前在果实生长前期施用,获得大面积良好防效。利用苹果炭疽病菌潜伏侵染特点,在侵染盛期或盛期过后,施用化学治疗剂(仲丁胺、乙磷铝等),北部苹果区喷1—2次药,南部苹果区喷2—3次药,初步试验可获得较好防效。每一万亩苹果树,减少一次打药可节约投资二万元左右。在黄河故道地区每年可减少4—5次药,将会大幅度提高经济和社会效益。在国内外,首次(1980年)利用无毒高脂膜防治苹果炭疽病成功,为植物病害防治开拓了新途径。 |

| Abstract: |
| During 1979 to 1983,the infection cycle and disease development of the apple anthracnose caused by Glomerella cingulata had been inten- sively studied.On the basis of the results of the studies,new means of its control had been worked out.By the application of the routine chemical spray such as Bordeaux mixture,tuzet etc.prior to the rapid growth of fruitS,good results of control were obtained in large areas of apple orchards.According to the character of the latent infection of this disease,application of ... |
