采用抗虫品种是水稻害虫综合防治技术的基础,实践证明,种植抗虫品种,既可省工、省药、保持生态平衡、又能达到减少环境污染的目的。“六五”期间我们先后与澄海县农科所、广东省农科院水稻所合作,开展抗虫育种研究,并受省种子公司及一些育种单位委
The adoption of insect-resistant varieties is the basis of comprehensive pest management techniques. Practice has proved that planting pest-resistant varieties can save labor and save medicine, maintain the ecological balance and reduce the environmental pollution. During the “Sixth Five-Year Plan” period, we cooperated with Chenghai County Agricultural Science Institute and Guangdong Provincial Academy of Agricultural Sciences in rice research to carry out insect-resistant breeding research, and by the provincial seed companies and some breeding units
