新型植物生长延缓剂多效唑在水稻、小麦、油莱、大豆等多种作物上应用,具有控制徒长,促进分蘖(分枝),增强代谢,提高产量的效果。杂交水稻采用两段育秧方式,可有效地提高秧苗素质,有利于培育出适龄壮秧。目前,多效唑已在信阳地区杂交水稻栽培中推广。针对生产实际,1990年我们进行了杂交水稻两段育秧施用多效唑试验,探讨多效唑在杂交水稻两段育秧中施用 The new plant growth retardants paclobutrazol in rice, wheat, oil Lai, soybeans and other crops on the application of control of leggy, and promote tillering (branching), enhance metabolism and increase production. Hybrid rice with two sections of seedlings, can effectively improve the quality of seedlings, is conducive to nurturing a suitable age seedlings. At present, paclobutrazol has been promoted in hybrid rice cultivation in Xinyang. For the actual production, we conducted two hybrid rice paddy in 1990, the application of paclobutrazol test to explore the application of paclobutrazol in hybrid rice two seedlings
