玉米不同播期与玉米粗缩病发生及产量的关系研究
THE RELATIONSHIP STUDY ON HTE DIFFERENT SOWING DATES,THE OCCURRENCE OF MAIZE ROUGH DWARF DISEASE AND YIELD
摘要
Abstract
From 2009 to 2011, the occurrence of L. striatellus and maize rough dwarf disease incidence and corn production of different corn sowing period was systematic investigation. The results showed that during 3 years the population dynamics of Laodelphgax striatellus adult was essentially the same from April 25 th to June 19 , reaching a peach at June 14th. Before April 30th and after June 19th, the incidence of the maize rough dwarf disease was significantly reduced. The morbidity of maize rough dwarf disease sowing during incident peak of small brown planthopper was the highest, and the losses of com yield seeding from May 20th to May 30th was the greatest. Therefore, the important factors affecting the occurrence of maize rough dwarf disease is sowing date. It is effective to avoid the peak of mass poisoning meet planthopper by appropriate early sowing or late sowing which can prevent the outbreak of maize rough dwarf disease.关键词
