分析12年来峨山县稻飞虱监测调查数据,明确了峨山县稻飞虱以白背飞虱为主;3、4代为主害代,虫源主要是本地虫源加代繁殖和境外虫源迁入;水稻5月下旬至6月上旬田间虫量(x1)和灯下累计虫量(x2)与植株受害敏感期6月下旬至7月上旬虫量呈极显著相关,回归模型y1=0.000 192 8x1+1.166 05,y2=0.000 365 8x2+1.055 96。
Based on the survey data of rice planthoppers monitoring in Asan County in the past 12 years, it is clear that planthoppers in Eshan County are mainly characterized by whitebacked planthoppers; (X1) and accumulated lampworm (x2) in late May to early June in rice were significantly correlated with insect susceptibility from late June to early July. Regression model y1 = 0.000 192 8x1 +1.166 05, y2 = 0.000 365 8x2 + 1.055 96.
