摘要
利用化学“杀雄剂2号”对水稻进行了不同药液浓度、不同品种(系)和不同叶枕距条件下的杀雄试验。结果表明:(1)“杀雄剂2号”对籼稻、粳稻及其中间类型的杀雄效果相近,适合化杀的品种范围广泛。(2)“杀雄剂2号”对水稻施药的有效期较长。(3)在当地生产条件下,施用0.05%浓度的药液对水稻可达到最佳的杀雄效果。
Experement of Male—-Gametocide No.2 to rice in different consistency,varieties,andgrowth stages showed:(1)Killing male effection to indica,japonica and intermediate type was similar.The va-rieties in which male could he killed widespreadly existed.(2)Effecting period of Male-Gametocide No.2 to rice was longer.(3)The best effection of killing male could be obtained with 0.05% male-Gameto-cide in local production condition.
