叶面肥对菜豆光合指标及植株性状的影响

以菜豆品种‘A18’为试验材料,采用叶面喷施的方法,研究了叶面肥对菜豆光合指标及植株性状的作用,以期探索叶面肥对菜豆的影响。结果表明:叶面肥可以显著促进幼叶的发育,与对照组相比处理组的叶面积增加9.6%;净光合速率最高可增加23.9%;此外测产结果表明,处理组较对照组第1茬产量提高7.6%,第2茬产量提高15.27%,全生长期增产10.44%。试验采用的叶面肥配方可以显著提高菜豆的光合效率,促进植株生长发育,提高菜豆产量。

Effects of Foliar Fertilizer on Photosynthetic Index and Plant Character of Phaseolus vulgaris L.

In order to explored the effects of foliar fertilizer on common bean’A18’common bean was selected as experiment materials,sprayed foliar fertilizer to study the effects of foliar fertilizer on photosynthetic index and plant characters.The results showed that foliar fertilizer could significantly promote the development of young leaves,and the leaf area of the treatment group increased by 9.6%compared with the control group.The net photosynthetic rate could increase by 23.9%at most.In addition,compared with the control group,the yield of the first crop increased by 7.6%,the yield of the second crop increased by 15.27%,and the yield of the whole growth period increased by 10.44%.The leaf fertilizer formula could be significantly increased the photosynthetic efficiency,promoted the growth and development of plant,and increased the yield of common bean.
