在砀山酥梨微肥“酥梨宝”优质增产试验的基础上,通过对“酥梨宝”微肥配方的适当调整,重新配制出葡萄微肥“双增灵”,在我省著名的葡萄产地萧县龙山和淮北市大庄两地,同时进行酿酒和鲜食品种的优质丰产试验。叶面肥试验表明:鲜食品种巨峰可溶性固形物平均增加1.97%,增幅达15%,总糖平均增加0.78%,增幅6%,维生素C平均增加1.259mg/100g,增幅达18%;酿酒品种白羽总糖平均增加0.59%,增幅5%,维生素C平均增加0.33mg/100g,增幅5%,产量平均提高5.07kg/株,增幅高达26.5%。同时,试验的葡萄果实中,对人体十分有益的硒(4～24倍)、锌(约1倍)元素含量也有了大幅度的提高。
Based on the high-yielding trial of Dangshan Superannuishao “Pear-Po”, through the proper adjustment of the formula of “Pear-Po” micro-fertilizer, the grape micro-fertilizer “Shuangzengling” Origin Xiaosong Longshan and Huaibei City Zhuang two places, at the same time brewing and fresh varieties of high-yield test. The foliar fertilizer test showed that the soluble solids of Kyoho peak increased by 1.97% on average, with an increase of 15%, the total sugar increased by 0.78% on average, an increase of 6%, vitamin C increased by an average of 1.259mg / 100g, an increase of 18% The total sugar of white plume increased by 0.59% and 5% respectively on average, while vitamin C increased by 0.33mg / 100g on average by 5% and the yield increased by 5.07kg / plant with an increase of 26.5%. In the meantime, the content of selenium (4 ~ 24 times) and zinc (about 1 times) which is very beneficial to the human body has also been greatly increased in the grape fruits tested.
