黑龙江省地处我国东北部,冬季气候寒冷,无霜期短,仅110～150天,活动积温(≥10℃)为1700～2750℃;一月份平均气温在-31℃-15℃。特定的气候条件,限制了葡萄生产的发展,一些优质、高产、大粒葡萄品种难以栽培成功,而小、酸、涩的地产果又难以满足消费者的需要,形成了供需矛盾。我所经过多年选择观察认为:乍娜品种具有早熟、粒大,质佳的特点。且较抗寒,经济效益庭院栽培优于红香水,保护地栽培优于巨峰群品种,是很有发展前途的庭院及保护地栽培品种。
Heilongjiang Province is located in northeastern China. The winter climate is cold and the frost-free period is short, only 110-150 days. The active accumulated temperature (≥10 ℃) is 1700-2750 ℃. The average temperature in January is -31 ℃ -15 ℃. Certain climatic conditions have limited the development of grape production. Some high-quality, high-yielding, large-grained grape varieties are difficult to cultivate. However, small, sour and astringent real-estate products are difficult to meet the needs of consumers and create a contradiction between supply and demand. After years of observation I have chosen to observe: Zacharian varieties are characterized by early maturity, large grains and good quality. And more cold-resistant, economic garden cultivation better than red perfume, protected cultivation is better than the Jufeng group variety, is a very promising garden and protected cultivars.
