| 摘 要： | 通过不同调查者调查相同稻田内二化螟为害的枯鞘、枯心和白穗等受害稻株,分析平均受害株率和平均受害丛率的关系。结果表明,“平均受害丛率”在不同调查者之间的误差小于“平均受害株率”。受害株率和受害丛率之间呈正相关的关系,当受害丛率小于60%时,受害株率与受害丛率的相关系数超过0.91,用受害丛率可以较准确地估计受害株率。 |

| Abstract: | Damaged rice plants like yellow sheaths,dead hearts and white heads from rice stem borer,Chilo supperssalis(Walker) were investigated by different investigators in the same rice fields to determine relationship between damage percentage of rice plants(DPRP) and damage percentage of rice clusters(DPRC.) The results showed that the error of mean DPRC was lower than that of mean DPRP.There is a positive correlation between DPRP and DPRC.When DPRC was lower than 60 percent,correlation coefficient of DPRP and DPRC was over 0.91,and then DPRP could be estimated correctly with DPRC. |
