摘要
洪泽县直播水稻纹枯病连年重发原因在于品种感病、高温高湿天气、栽培措施利于发病及防治技术不到位等。防治水稻纹枯病应以农业防治为基础,采取合理密植、加强肥水管理等农业措施,改善直播水稻的生长环境条件,并及早用药进行保护,如24%噻呋酰胺SC300 ml/hm2、6%井冈·蛇床素WP 900 g/hm2等。
Grave occurrence reasons in successive years of rice sheath blight in direct seeding rice field in Hongze Country were that rice varieties suscepti-ble to disease, high temperature and hu-midity weather, inadvisable cultivate measures, and control techniques was not in place.Rice sheath blight should be controlled on the basis of agricultural control, and agricultural measures such as rational close planting, strengthening fertilizer and water management should be taken in order to improve direct-seeding rice growth environment and conditions. And the rice should be pro-tected by spraying insecticides as soon as possible, such as 24% thifluzamide SC 300 ml/hm^2, 6%Jinggangmycin cni-diadin WP 900 g/hm^2.
