摘  要:
在三江平原大豆主产区设立气象观测站,监测2005~2010年6年中7月、8月(大豆灰斑病易感期)日降水量,同时在气象站周围种植易感大豆灰斑病品种合丰45号,定点定株逐日调查和记录大豆灰斑病病情指数。初步确定三江平原大豆灰斑病易感期降水量对大豆灰斑病的影响。结果表明,大豆灰斑病发生与7月上旬、下旬降雨量呈显著正相关。在此基础上8月下旬遇到较强降水,易发生大豆灰斑病,严重时将发生流行。

摘  要:
The research set meteorological station at soybean production area in Sanjiang plain area,and monitored the daily raifull of July and August from 2005 to 2010.At the same time,the researcher planted the susceptible variety Hefeng45 around the station,and investigated the disease index of soybean frogeye leaf spot at the fixed-point and fixed-plant.The research determined the effects of rainfull on the soybena frogeye spot leaf in the susceptible period in Sanjiang plain area primarily.The results showed that the severity of soybean frogeye leaf spot was positively correlated with the rainfull at the end of July and the beginning of August.If the rainfall is rich at the end of July,it will appear outbreak of the soybean frogeye leaf spot.
