水稻品种多样性栽培防治稻瘟病试验初报

A Preliminary Investigation of Rice Blast Control via Diversity Cultivation of Cultivars

通过对7个不同水稻品种的多样性栽培试验,以研究不同水稻品种之间混栽对稻瘟病的防治效果。结果表明:不同水稻品种之间混栽对稻瘟病均有控制效果。其中,品种间栽,尤其是感病品种与杂稻品种间栽对稻瘟病的防治效果极其显著。混合间栽可以提高水稻产量。

To verify the effects of mixed cultivation of different cultivars on rice blast control, seven rice cultivars were used in cultivar diversity cultivation experiment herein. The results revealed that mixed plantation using different rice cultivars might considerably control rice blast. Among the tested planting methods, cultivar-mixed cultivation, especially the inter-plantation between susceptible and hybrid ones, gave significant effect on rice blast control. It also showed that mixture inter-planting could somewhat increase the rice output.
