摘要
2,3,5——三碘苯甲酸是一种植物生长调节剂,具有抑制生长促进发育的作用.可使大豆降低株高,节间缩短、改善田间通透性,达到抗倒增产的目的.适于诱变30号、诱变31号、科系170—4等植株高大、营养体繁茂的品种喷施.繁茂性中等而植株高大的冀豆4号、科丰6号用药浓度可适当降低,繁茂性差的品种和夏播大豆一般不要喷施.喷施的最佳时期为初花期,用药量为每亩4～5克.
2, 3, 5-Triiobenzoic acid is a plant growth regulator having effctsof retarting
growth and promoting devolopment. It makes soybean lower hieght, reduce internode, im-
prove field aeration, resist lodging and increase yield Luxuriant cultivars, such as mutation
No. 30, mutation NO. 31 and KE -XI 170 - 4 are suitable to spray with it; nedium luxuriant
ones, such as JI-DOU No. 4, KE-FENG No. 6 can be sprayed with lower concentration
solution; summer-sown and weak-grown ones do not be sprayed. The optimum period to
