| 摘 要： | 对夏大豆进行全程化控试验。结果表明:在15%多效唑施用总量750 g/hm2条件下,以分枝期300 g/hm2+初花期450 g/hm2处理效果最好,大豆增产17.1%,达显著水平;苗期75 g/hm2+分枝期150 g/hm2+初花期300 g/hm2+盛花期225 g/hm2处理增产13.7%,初花期300 g/hm2+盛花期450 g/hm2处理增产11.4%,但较对照均未达显著水平。3种全程化控方法均能增加叶绿素含量,降低株高和结荚高度,增加株荚数、株粒数和株粒重,但对百粒重影响较小。采用全程化控技术具有控制大豆旺长和提高产量的效果。

| Abstract: | The whole chemistry control of soybean was studied.The results showed that the effect of spraying 300 g/hm^2 15% paclobutrazolat at branching stage and 450 g/hm^2 15% paclobutrazol at initial flowering stage was the best,the yield increased by 17.1%,which reached significant level than other treatments.The effect of spraying 75 g/hm^2 15% paclobutrazol at seedling stage,150 g/hm^2 15% paclobutrazol at branching stage,300 g/hm^2 15% paclobutrazol at initial flowering stage and 225 g/hm^2 15% paclobutrazol at full flowering stage took the second place,and the yield increased by 13.7%.The effect of 300 g/hm^2 15% paclobutrazol at initial flowering stage and 450 g/hm^2 15% paclobutrazol at full flowering stage was the least.All the three chemistry control methods could increase the chlorophyll content,number of pods per plant,number of seeds per plant and seed weight per plant,decrease the plant weight and height of first pod,and had little influence on 100-seed weight.The whole chemistry control could control vigorous growth of soybean and increase the yield. |
