| 摘 要： | 在湘北油稻稻三熟制区晚稻超高产栽培条件下，进行了两系杂交组合培两优特青“三虫两病”发生特点、种群消长、演替规律及影响种群变动因素的研究。结果表明：水稻超高产栽培条件下更有利于病虫繁衍，发生量和危害程度均有加重趋势，在时空结构及危害特点上都出现了一些新的变化。

| Abstract: | In the north of Hunan Province, Peiliangyou Teqing, a commercial two-line hybrid rice, was cultivated under the super-high-yield culture in tricropping pattern of rape-rice -rice. The studies were conducted on the occuring characters, the developmental dynamics patterns of the populations of three pests and two diseases and their influencing factors. The results suggested that the super-high-yield cultural conditions were more favourable for the reproduction and occurrance of the diseases and pests, consquently, the damage of them became more serious, and some new changes appeared in the occuring and damaging of diseases and pests in time and space. |
