| 摘 要： | 玉米粗缩病的发生与病毒侵染时玉米植株的生育期关系密切。研究表明 ,普通玉米品种 6叶龄以下为敏感生育期 ,6叶龄以上为非敏感生育期。目前生产上种植的杂交玉米适播期较长 ,如能根据传毒昆媒灰飞虱的消长、传毒规律 ,合理确定玉米播种期 ,使玉米敏感生育期最大限度地避开灰飞虱传毒盛期 ,即可避免或大幅度减轻玉米粗缩病的危害。江苏盐城地区春玉米在 4月上中旬、夏玉米在 6月中旬播种 ,玉米粗缩病发生程度轻。因此 ,上述时间是防治玉米粗缩病的安全播种期

| Abstract: | Occurrence of rough dwarf disease of maize closely associated with growth stage of maize during the disease infection.For the ordinary maize varieties at over six leaf stage were relatively safe,while those at under six leaf stage were susceptible to maize rough dwarf disease(MRDD).Due to the long suitable date of seeding for large scale cultivated hybrid maize varieties,the seeding date could be selected to keep away from infection peak of insect vector-the small brown planthopper(SBPH)( Laodelphax striatellus) according to its occurrence and transmission regularity and to avoid severe damage by MRDD.In Yancheng of Jiangsu province,the most suitable seeding date for spring maize is in the first and second ten days of April and that for summer maize is in the second ten days of June. |
