在当地为害水稻的稻飞虱优势种以褐飞虱为主;水稻霉污的形成与稻飞虱的为害有着显著的相关性;霉污为害等级与结实粒数、千粒重、穗粒重呈显著的负相关,与空秕率、损失系数呈显著的正相关。不同虫口密度也与结实粒数、千粒重、穗粒重呈显著的负相关,与空秕率、损失系数呈显著的正相关。防治指标始穗期应控制在每株5头以下。
The dominant species of rice planthoppers in the area were Nilaparvata lugens; the formation of rice mold pollution was significantly correlated with the damage of planthoppers; the degree of mold pollution and the number of grains, grain weight and spike weight were significantly negative Correlation, and the empty rate, loss coefficient was significantly positively correlated. The population density of different insects also had a significant negative correlation with grain weight, grain weight and grain weight, and had a significant positive correlation with the rate of ridges and loss coefficients. Control index should be controlled at the beginning of each plant 5 head or less.
