不同植物生长调节剂对大豆产量及生长形态的影响

Effects of Different Plant Growth Regulators on the Yield and Grow Shape of Soybean

[目的]研究植物生长调节剂对大豆产量及生长形态的影响。[方法]以4个不同大豆品种为材料,研究了大豆始花期喷施不同生长调节剂及其混剂对大豆产量及生长形态的影响。[结果]不同植物生长调节剂在不同品种上的效果各不相同。综合比较表明,喷施硅丰环6 000倍液,对改善大豆植株性状,增加产量、单株荚数和单株粒数的效果最优;喷施硅丰环6 000倍液+复硝酚钠6 000倍液和芸苔素1 000倍液+复硝酚钠6 000倍液+矮壮素1 000倍液对改善植株性状,增加产量、单株荚数及单株粒数也有较好的效果。[结论]该研究对植物生长调节剂在大豆高产栽培中的应用具有指导意义。

[ Objective ] The research aimed to study the effects of plant growth regulators on the yield and grow shape of soybean. [ Method ] Choosing 4 kinds of soybean varieties as materials, the effects of spraying different growth regulators and their mixture at initial flowering stage on the yield and grow shape of soybean. [ Result ] The results showed that different plant growth regulators had different effects on different species varies. Comparison showed that silatrane 6 000 times liquid had the best effects of improving the plants traits of different soybean varieties, increasing yield, pod number per plant and grains per plant. The treatments of silatrane 6 000 times liquid ＋ sodium nitrophenolate 6 000 times liquid and brassin 1 000 times liquid ＋ sodium nitrophenolate 6 000 times liquid ＋ cycocel 1 000 times liquid also had good effects. [ Conclusion] The study has significance for applying plant growth regulators in soybean high yield cultivate.
