不同施锌方式对小油菜产量和品质的影响

The Effects of Different Zinc Application Methods on the Yield and Quality of Rape

为明确最适宜的富锌小油菜培育方式,以小油菜为试验对象,设置了不同施锌处理。结果表明:与对照相比,底施锌、喷施锌、底施和喷施相结合的3种施锌处理小油菜产量分别提高14.8%、7.4%、18.5%,锌含量分别提高2.0%、23.7%和41.1%。综合分析,建议选用底施3 g/m^2的硫酸锌加喷施0.1%硫酸锌的方式来进行富锌小油菜的培育。

In order to identify the optimum cultivation way of zinc-riching rape,with rape as test object,different zinc application methods were set up,which included the base zinc application,spraying zinc and two ways together.The results showed that compared with the control,the yield of above different zinc treatments increased by 14.8%,7.4%,18.5%,and the zinc content increased by 2.0%,23.7% and 41.1%.In conclusion,the zinc application method by combining the base fertilizer application of 3 g/m^2 and spraying 0.1% zinc sulfate was the best way to cultivate zinc-riching rape.
