Abstract
The initial stage, shock stage and occurrence degree of early rice sheath blight with hand transplanting, machine transplant-ing and direct seeding were studied. The results showed that the initial stage of sheath blight with hand transplanting was earlier 5 days than the other two planting patterns in the same sowing date;the shock stage of sheath blight with direct seeding was earlier 10~20 days than the other two planting patterns. The disease index of sheath blight performance: direct seeding > hand transplanting >machine transplanting, the disease index of direct seeding was significant heavier than that of the other two planting patterns at 15~20 d after the initial stage of sheath blight, the disease index of hand transplanting and machine transplanting had no significant differ-ence. Therefore, we should pay more attention to the control of sheath blight and practice early in direct seeding early rice.关键词
