为了有效降低水稻鞘腐病的危害,以主栽品种空育131为试材,设置不同的栽培密度,调查水稻鞘腐病的发病率与病情指数。结果表明:在29.7 cm ×13.2 cm插秧规格下,鞘腐病病情指数随着栽培密度的增加呈递增趋势,每穴4株时病情指数为6.9,每穴6株时病情指数为10.5,每穴8株时病情指数为10.9,每穴10株时病情指数为13.2。生产中建议选择每穴6~8株的插秧密度。

In order to effectively reduce the harm of rice sheath rot disease ,taking Kongyu 131 as experimental material ,the incidence and disease index of rice sheath rot disease were investigated with different planting den-sity .The results showed that the disease index of sheath rot increased with increasing planting density in the 29 .7 cm × 13 .2 cm planting specifications .Disease index was 6 .9 in 4 plants per hole ,disease index was 10 .5 in 6 plants per hole ,10 .9 in 8 plants per hole ,13 .2 in 10 plants per hole .In production ,it was suggested to select the density of 6~8 plants per hole for transplant .
