摘要: 为明确不同栽培方式与水稻细菌性基腐病危害程度的关系,在田间比较了5种水稻栽培方式(直播、小苗手插、大苗手插、小苗机插和大苗机插)对病害发生程度和水稻产量损失的影响。结果表明,直播田发病最轻,水稻产量损失最小;大苗机插发病最重,产量损失最大。移栽种植时,小苗机插发病较轻,病丛率显著低于小苗手插、大苗手插和大苗机插。因此,从细菌性基腐病控制的角度,在生产中推广直播或者小苗机插的栽培方式更有利于控制该病害发生。

Abstract: In order to verify the effects of different cultivation methods on the occurrence degree and yield loss of the rice bacterial foot rot, five different cultivation methods(direct seeding, hand transplanting with 15 day seedling age, hand transplanting with 24 day seedling age, machine transplanting with 15 day seedling age and machine transplanting with 24 day seedling age) were studied in the rice fields. The results showed the rice bacterial foot rot occurred lightest in direct seedling rice filed, and the yield loss was the lowest; the rice bacterial foot rot occurred heaviest by machine transplanting with 24 day seedling age, and the yield loss was the highest. The incidence of the rice bacterial foot rot by machine transplanting with 15 day seedling age was significantly lower than hand transplanting with 15 day seedling age, hand transplanting with 24 day seedling age and machine transplanting with 24 day seedling age. From the point of view of control disease, direct seeding or machine transplanting with 15 day seedling age is more beneficial to control this disease during rice production and promotion.
