花生增果剂对花生生长发育及增产效应的初步研究

Effect of Zeng Guo Ji on Growth Development and Yield of Peanut

试验结果表明,初花期喷施3种花生增果剂均可调控花生植株的生长发育,使其株高降低,分枝增多,叶绿素含量和光合速率提高,根部结瘤增多,获得较合理的株型结构;并可使单株结果数、饱果率和百果重增加,表现出明显的增产效应。在3种增果剂中,以增果剂3号综合效应最好,可使每hm^2增产花生荚果730.5kg,增产率15.8％,产投比为68.2:1,经济效益显著,有较高的应用价值。

Three kinds of Zeng Guo Ji (chemical for increasing pod yield) were sprayed on peanut plants at early flowering stage to determine their effect on growth and development of plant and pod yield. The results indicated that all the three kinds of Zeng Guo Ji could cause a decrease in plant height and increase in chlorophyll content, photosynthetic rate,number of branches and root nodules. In addition, the pod number per plant, percentage of full pod,100-pod weight and pod yield per hectare were increased obviously. Maximum yield was obtained with Zeng Guo Ji NO. 3 treatment.
