化学“杀雄剂2号”对水稻的化学杀雄效果分析

STUDY ON KILLING MALE EFFECTION OF “MALE—GAMETOCIDE NO.2” TO RICE

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。

Abstract:

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 varieties 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-Gametocide in local production condition.
