“巨峰”是原产日本的四倍体大粒葡萄。上海于1967年春引种,由于栽培技术陈旧,生产效果不佳,成年树平均亩产约在500公斤左右,栽培失败的也不少。近十余年间,日本在“巨峰”栽培上研究出不少新技术,我们自1983年冬采纳这些观点,因地制宜地加以应用和发展,终于使“巨峰”葡萄连年丰产,创国内同龄“巨峰”的最高水平。此外,还采用边试验、边推广的办法,编写了“葡萄科普简报”、“上海地区‘巨峰’葡萄栽培技术规范(草案)”,使接受指导的一些幼龄巨峰园在栽后第二年的产量达到1000公斤以上。高的达到2000多公斤,产值2500～5000元左右。1986年“巨峰”葡萄栽培新技术的推广面积已达1500余亩,年经济效益可达300万元以上。
Kyoho is a tetraploid large-grapes grape native to Japan. The introduction of Shanghai in the spring of 1967, due to outdated cultivation techniques and poor production results, the average adult mu yield was about 500 kg per mu, with many unsuccessful cultivation. In the past ten years or so, Japan has developed many new technologies in the cultivation of “Jufeng”. Since the adoption of these views in the winter of 1983, it has been applied and developed in accordance with the local conditions. At last, the “Jufeng” “The highest level. In addition, using the side of the test, while promoting the way, prepared the ”grape science briefing,“ ”Shanghai Kyoho grape cultivation technical specifications (draft)“, so that some of the guidance young Jufeng Park planted the second year The output reached more than 1000 kilograms. High to reach more than 2,000 kilograms, the output value of 2500 to 5000 yuan. 1986 ”Kyoho" viticulture new technology promotion area has reached more than 1,500 acres, the annual economic benefits of up to 3 million yuan.
