黑龙江省植检植保站日前称,今年全省春季气温变化幅度较大,冷暖空气活动频繁,升、降温过程明显,特别是近期温度骤升,易造成秧苗徒长、抗病性降低,加之个别稻农苗床管理不当,目前部分地区水稻苗床已有病害零星发生。据近日各水稻主产县植保站调查监测,肇源立枯病发病棚室率3.3%,发病棚病株率0.1%;肇东、泰来、富锦零星发生。阿城、密山、北林、绥棱零星发生绵腐病,五常、富锦个别苗床零星发生恶苗病,阿城、庆安、桦南等地个别苗床还出现除草剂药害等造成的白苗现象。黑龙江省植检植保站表示,目前全 Heilongjiang Province Plant Protection Plant Protection Station recently said that the province’s spring temperature changes this year, a larger range, frequent cold and warm air activity, or cooling process is obvious, especially the recent temperature surge, easily lead to leggy seedlings, disease resistance decreased, coupled with individual rice Improper management of seedbed, the current rice seedbed in some areas have been sporadic disease. According to recent surveys and surveys of the plant protection stations in the main producing counties of rice, the shed incidence rate of the dead blight of Zhaoyuan is 3.3% and the rate of shedding diseased plants is 0.1%. Zhaodong, Tailai and Fujin sporadically occur. Acheng, Mishan, Beilin, Suiling sporadic Mian rot disease, Wuchang, Fujin sporadic individual nursery bed sickness occurred, Acheng, Qing’an, Huanan and other places also appeared individual seedbed herbicide injury and other white Miao phenomenon.
