核酸生物肥主要成分有核酸、氨基酸、有机酸及胡萝卜素等,它具有增加坐果、提高果实着色和改善果实品质等作用,在日本果树生产上已广泛使用。为了探索该肥在我地区葡萄上的作用,苏州市科委从日本引进核酸生物肥系列产品日本3号、4号、6号肥,于1992年在吴江市林果良种场葡萄园进行试验。试材为6年生巨峰葡萄,篱架栽培。供试核酸生物肥有日本3号、4号、6号肥(日本国三井东压肥料株式会社产品)。试验设4个处理:处理1于花前20d(天)起,共喷布4次1000倍日本4号肥,每隔7d喷1次;处理2于花前20 d(4月30日)起,喷布8次1500倍日本6号肥,每隔7d喷1次;处理3于幼果开始生长(5月28日)起,喷布4次1000倍日本3号肥,每隔7d喷1次;对照(不喷肥)。各处理均为3株小区,2次重复,4个 Nucleic acid bio-fertilizer main components of nucleic acids, amino acids, organic acids and carotenoids, which has the effect of increased fruit set, improve fruit coloring and improve fruit quality, fruit production in Japan has been widely used. In order to explore the role of this fertilizer on the grapevines in our region, Suzhou Science and Technology Commission imported the Japanese No.3, No.4 and No.6 fertilizers of nucleic acid biological fertilizer products from Japan and tested them in 1992 in the vineyard of Linguoliang variety field in Wujiang City. The test material is a 6-year-old Kyoho grapes, rape cultivation. The test nucleic acid biological fertilizer Japan No. 3, No. 4, No. 6 fertilizer (Japan’s Mitsui Toho fertilizer Co., Ltd.). The experiment set up 4 treatments: Treatment 1 Spray 1000 times of Japanese No.4 fertilizer four times in total, spraying once every 7 days from the day before flowering 20 days (days); Treatment 2 beginning 20 days after flowering (April 30) , Spraying 8 times 1,500 times Japan 6 fat, spraying every 7d 1; treatment 3 in the young fruit began to grow (May 28), 4 times 1000 times sprayed on the 3rd fertilizer, spray 1 every 7d Times; control (no fertilizer). All treatments were 3 plots, 2 replicates and 4 replicates
