| 中文摘要: |
| 根据稻象甲虫量与水稻产量的关系 ,结合现行的稻谷价格 ,产量水平和防治费用等因素 ,进行了稻象甲危害损失的测定 ,制定了稻象甲的防治指标。采用累积虫日作为防治指数 ,确定了在江西境内稻象甲的防治适期 |
| 英文摘要: |
| Based on the relationship between population density of Echinocnemus squameus and rice yield loss, combined with rice price, yield level and control costs, the rice yield losses caused by E. squameus were tested, and the economic thresholds of controlling E. squameus were set up. With cumulative insect-day as control index, the optimum control period of E. squameus was determined in Jiangxi Province. |
