| 摘 要： | 试验结果表明,在相同水稻生育期和相同二化螟虫量下,杂交稻损失大于常规稻,早稻损失大于晚稻。并用改进的二化螟防治指标计算方法算出杂交早、晚稻二化螟防治指标,经检验,比传统的计算方法算出的防治指标准确、简便、实用。

| Abstract: | The experimental results showed that under identical population
densities of rice striped borer Chilo suppressalis(Walker)in the same
developmental stage of rice caused more yield loss of hybrid rice and
early rice than of common rice and late rice,respectively.The action
threshold of this insect pest on early and late hybrid rice were deve-
loped with an improved calculation method,and field tests indicated
that this improved method was more accurate,convenient and practical
than former ones. |
