| 摘 要： | 通过小区对比试验,探讨了种子不同处理对水稻干尖线虫病危害的影响。结果表明:采用20%稻乐丰乳油1 000倍液+10%浸种灵5 000倍液浸种消毒防病效果最好,干尖线虫病穴发病率仅为0～3.4%;其次是80%敌敌畏乳油1 000倍液+10%浸种灵5 000倍液浸种消毒,病穴发病率为0～13.2%;去掉种子颖壳用纸隔离后播种,对干尖线虫病的防治效果位居第三,病害穴发病率0～21.4%。水稻遭受干尖线虫病危害,由于单位面积收获穗数、颖花量、结实率、千粒重均有一定程度的降低,进而造成了水稻的大幅度减产。

| Abstract: | Because of aphelenchoides besseyi,the effective panicles per unit area,flowers,percentage and 1 000 grains weight has a certain extent reduce and rice production was greatly reduced.through the comparative tests,the results indicated that use treatment of 20%daolefeng(EC) in 1 000 times+10%jinzhongling in 5 000 times to soak seeds can achieve the best effect on Aphelenchoides besseyi which made morbidity less than 3.4%,the second was treatment of 80% didiwei in 1 000 times + 10% jinzhongling in 5 000 times ... |
