摘要
在田间实施单株接卵量分别为20、40、60粒和自然发生、空白对照等5个处理,目的是弄清田间玉米螟卵量对玉米的危害状及产量损失影响。试验结果表明:接不同玉米螟卵量对玉米所形成的危害状及产量的影响存在着显著性差异。并由产量损失率与卵量线性关系可得方程为Y=0.7432x(R2=0.8582),在以1代为主的地区或1代区,提前可根据玉米螟的危害状的调查,参照本项试验结果,来预测玉米螟危害玉米的产量损失情况。
In order to find out the influence of the quantity of corn borer on the damage and yield losses of maize, the author carried out the experience that separately put 20, 40, and 60 corn borer eggs on each corn plant and compared them with the untreated plants and those with no egg. The result showed that the plants with more eggs was damaged more seriously than the less ones, and the relationship between yield loss and the egg amount is Y=0.7432x （R^2=0.8582） .
