通过对核桃黑斑病、核桃炭疽病、核桃褐斑病、核桃长足象、核桃举肢蛾、桃蛀螟、双鬃尖尾蝇、栗黑小卷蛾、高隆象等核桃果实的病虫害调查研究,总结出核桃果实病虫害的无公害综合治理技术。该技术可以在冬季清理核桃园时,在树盘下铺一层地膜,提高土壤温湿度,这样不利于病害虫越冬,也使害虫在翌年出蛰成虫时无法出土,不仅有利于核桃树的越冬保暖、保持水分而且避免使用农药污染环境,避免用药时机掌握不好而错失防治适期。
The pests and diseases of walnut fruits such as walnut black spot, walnut anthracnose, walnut brown spot, walnut long foot elephant, walnut thorn moth, decapitation borer, double bristle tip fly, black chestnut moth, Research, summed up walnut fruit pests and diseases of pollution-free comprehensive treatment technology. The technology can clean the walnut in the winter when the tree under the shop a layer of plastic film to improve the soil temperature and humidity, which is not conducive to disease pests wintering, but also insects in the following year out sting adults can not be unearthed, not only conducive to winter walnut trees warm , To maintain moisture and avoid the use of pesticides to pollute the environment, to avoid medication timing is not good and missed the appropriate period of prevention and treatment.
