摘要
本试验通过对接种黄萎病的地块进行不同浇水次数的处理来调查分析浇水次数对向日葵黄萎病发生程度及产量的影响。结果表明随着浇水次数的增多,向日葵黄萎病的发病严重度也随之增加,且向日葵的产量呈现降低的趋势。在接种的地块中浇水1次的病情病指由29.0递增到浇水3次51.5;产量则由浇水1次的4690.95kg/公顷降低至浇水3次的3815.55kg/公顷。
In this experiment,the effects of watering frequency on the sunflower yellow wilt disease index and sunflower yield were studied in artificial inoculated field.Our data suggested that the more watering frequency,the much more severe of disease index.Watering in the inoculated plots 1 times to 3 times,the disease index of Verticillium wilt showed an increasing tendency,(form 29.0 to 51.5);meanwhile,the sunflower yield decreased from 4690.95 kg /ha,down to 3815.55 kg /ha.
