我们于1987年春引入黑丰葡萄新品种随即定植,该品种1989年前全国只有三家占有。引入三年以来,对它的生态、生物学特性及苗木繁育进行了较为全面地观察与探索。确认黑丰葡萄是有发展前途的优良品种,也是新区难得的主栽品种。 In the spring of 1987, we introduced a new variety of black grapes and then colonized it, only three of which were owned by the country before 1989. Since its introduction three years ago, its ecological, biological characteristics and seedling breeding have been more comprehensive observation and exploration. Confirming black grape is a good variety of promising, but also a rare new varieties of the main area.
