春大豆喷施植物生长调节剂生产性状的研究

STUDY ON HIGH YIELD PERFORMANCE OF SPRING SOYBEAN SPRAYING PLANT GROWTH REGULATOR

豆科作物高肥密植常因徒长和落花落美而减产。针对这一问题,作者报道了用不同植物生长调节剂喷施春大豆,进行高肥密植丰产性状研究。试验结果表明:以大豆花芽分化期,喷施80PPM的DPC和600倍爱多收混合液复合型植物生长调节剂增产效果最好。

In the condition of heavy fertilization and condensed planting,the yield of pod-bearing plant reducted because of spindling and blossom and fruit droping. Being derected against this issue,authors spraied the spring soybean with several plant grovrth regulators in order to carry on experiment of high yield performance under the conditions of heavy fertilizarion and condensed planting. The resul t shows that in the period of floral bud of soybean differentiation to spray DPC at 80 ppm and plant growth reg黮ator(600x) ,com-pound), the effect is the best.
