台湾葡萄栽培面积已达5000公顷,生产量相当大。但美中不足是,无论鲜果外销或葡萄汁、葡萄酒加工,其品质均未达到应有的水准。目前,除努力培育优良品种外,还从施肥管理入手进行探讨。采用了葡萄叶柄营养诊断和土壤养分测定相结合的方法,探索合理施肥。经多年的试验观察、分析比较,证实了应用上述方法指导施肥,效果很好,简便易行;因而确定采用,大力推广。
Taiwan viticulture area has reached 5000 hectares, a considerable amount of production. However, the fly in the ointment is whether the export of fresh fruit or grape juice, wine processing, its quality did not meet the required level. At present, apart from efforts to cultivate fine varieties, but also from fertilizer management to start with. Using grape petiole nutrition diagnosis and soil nutrient determination method of combining to explore the rational fertilization.
