华南师范大学研究结果表明,多效唑和粉锈宁都有抑制内源赤霉素生物合成的作用,抑制营养生长,增加果重。粉锈宁还能延长叶片寿命,增产作用比多效唑强。于花生始花后25一天下午喷药,用药量100L/亩。1987年试验结果,喷施多效唑25、50和100mg/kg,比清水对照分别增产7.57％、8.66％和6.78％,喷粉锈宁300、400和500mg/kg,分别比对照增产9.69％、10.50％和11.38％。1988年试验结果,喷多效唑25、50mg/kg,分别比对照增产6.61％ South China Normal University research results show that paclobutrazol and triadimefon inhibited endogenous gibberellin biosynthesis, inhibit vegetative growth, increase fruit weight. Triadimefon can prolong the life of the leaves, the effect of increasing production is stronger than that of paclobutrazol. In the peanut 25 days after the beginning of the afternoon spraying flowers, dosage 100L / acre. In 1987, spraying paclobutrazol 25, 50 and 100 mg / kg, respectively, increased 7.57%, 8.66% and 6.78%, spraying 300, 400 and 500 mg / kg respectively, 11.38%. 1988 test results, spraying paclobutrazol 25,50 mg / kg, respectively, compared with the control 6.61%
