| 摘 要： | 为阐明水稻播种期和移栽期对主要病虫害发生和为害的影响,2006—2007年在浙江北部嘉兴单季稻区进行了4个移栽稻播种、移栽期和3个直播稻播种期对本地越冬的病虫(二化螟、灰飞虱和纹枯病)种群动态和为害程度的试验。结果表明,水稻播种期是影响病虫害发生和为害的重要因子,随着单季晚稻播种期的推迟,二化螟、灰飞虱和纹枯病的发生和为害在水稻不同生育期均明显减轻。适期播种(5月底至6月初)是控制本地越冬的二化螟、灰飞虱、纹枯病等病虫害的有效方法之一。

| Abstract: | To elucidate the effect of sowing and transplanting date on the occurrence of locally-overwintering insect pests and disease in Yangtze Delta Rice Production Region,two-year field experiments in transplanted rice fields with 4 sowing-transplanting dates and directly-sown fields with 3 sowing dates were carried out,and the densities of the striped stem borer Chilo suppressalis,the small brown planthopper Laodelphax striatellus and the sheath blight Rhizoctonia solani(Thanatephoris cucumeris) were monitored r... |
