魏可葡萄叶面肥富硒的应用效果研究

The Research On Experiment Of Enriching Selenium By The Surface＇ s Absorpation Of Leaf In the Weike Grapevine

本文探讨在魏可葡萄植株生长发育阶段喷施含亚硒酸钠（Na2Se03）的氨基酸硒液叶面肥生产富硒葡萄的应用效果。以苏南地区优势果品魏可葡萄为材料，在叶面上喷施富含硒源（Na2Se03）的葡萄富硒液，使无机硒通过植物叶片的吸收，经植物生理代谢转化为有机硒而贮存在魏可葡萄果实内，探讨叶面肥葡萄富硒的应用效果。结果表明：在不施硒的条件下，魏可葡萄果实内的硒含量为6μg／kg。从葡萄生长的绽花、初花、盛花、初果等时期开始叶面肥喷施，葡萄果实内硒含量累积到54、44、36、32μg／kg，比对照组增长4．3～9．0倍，且不同富硒时期与富硒效果呈显著正相关关系（1t2=0．9675），葡萄氨基酸叶面肥富硒效果明显。

The article studied the applied effect of enriching Se concentration （Na2SeO3 ） in the Weike grapevine by the surface＇ s absorpation of aminophenol-Se fertilizer. The result showed that an initial Se concentration in control was only 5 p^g/kg in berries without Se-treatment. Se concentration in berries was rose steadily at the different phonological stages in Se-treatment, and reached 54,44,36,32 μg/kg,4.3 9.0 times to the blank berries. Se concentration in analyzed parts was mostly corresponded with the effect of enriching Se concentration and the different phonological stages of grapevine was noticed （ R2 = 0. 9675）.
