| 摘 要： | 水稻病虫总体调查、预报是与总体化防相配套的测报技术。它从稻田生态系统出发,调查研究水稻—有害生物—有益生物—环境—管理的多维关系,并以水稻生育期为阶段进行总体预报。文章介绍了总体调查预报的基本方法,并对病虫的总体组成和主、次种类,总体发生程度、总体发生期和防治适期等进行了初步界定。

| Abstract: | The technique on overall investigation and forecast is matched with overall chemical control. Based on the rice ecological system, the relationship of rice, pests, useful organisms, environment and management id studied, and the overall forecast is made at different growth period of rice. In this paper, the basic method of overall investigation and forecast was described, and the data of rice diseases and pests such as overall form, main and secondary kinds, overall occurrence degree, overall occurrence period, and optimum control time is determined. |
