摘要:
为利用新型栽培模式解决黑龙江省玉米大斑病发生严重难以防治的问题，于2016年通过对三空栽培模式和常规栽培模式下不同时段玉米大斑病病情指数进行调查，采用DPS软件分析了两种栽培模式下病害发生情况。结果表明：三空栽培模式秋季的病情指数为59.78，极显著低于常规模式的68.58，同时，5个地点的试验平均病情指数三空栽培模式比常规模式低12.38%，产量提高了4.02%。 说明三空栽培模式对大斑病的防治有一定的促进作用，同时也不减产。
Abstract:
In order to use the new cultivation mode to solve the problem of serious and difficult prevention and control of northern leaf blight on maize in Heilongjiang province.In 2016,the northern leaf blight on maize was studied in the “three empty” cultivation mode and conventional cultivation mode.Through the investigation of the disease index at different times，DPS software was used to analyze the difference between the two disease patterns.The results showed that the disease of “Threeempty” cultivation pattern index was 59.78 in autumn,which was significantly lower than that of conventional model 68.58,at the same time,the average disease index of the five sites was 12.38% which was lower than that of the conventional model and the yield increased by 4.02%.Threeempty cultivation mode had a certain effect on the prevention and treatment of big spot disease.
