摘要
试验以马铃薯"克新13"为试材,采用不同浓度硫酸锌(0、0.05%、0.1%、0.2%、0.4%)进行叶喷处理,通过测定马铃薯地上干重、地下干重、根系活力、叶绿素含量、根体积、产量等相关指标的变化,研究硫酸锌叶喷处理对马铃薯产量形成的作用效应。结果表明:适宜浓度硫酸锌(0.2%)叶面喷施处理能有效地提高叶绿素含量和根系活力,促进淀粉、块茎的形成,从而提高马铃薯产量;过量则限制了马铃薯块茎的形成,从而影响马铃薯质量及产量指标。
The experiments to Kexin No.13as material,using different concentrations of zinc sulfate（0,0.05%,0.1%,0.2%,0.4%） YePen processing,through the determination of dry weight,potato underground dry weight and root vigor,chlorophyll content,root volume,production related indexes,the change of potatoes YePen zinc sulfate research with the effect of yield formation.Results show that：the appropriate concentration of zinc sulfate（0.2%） foliar spraying treatment can effectively improve the chlorophyll content and root activity,promote the formation of starch,tuber,thereby improving production,Excessive,the potato tuber forming limit,thereby affecting the quality and yield of potatoes.
