河北省崇礼县高家营乡乌拉哈达村林业队,为提高大田栽植葡萄达到当年栽苗、当年放条、次年结果的目的。在塑料大棚内用大塑料袋培育巨峰葡萄苗获得成功。平均成活率达95.5％,苗高5—10厘米,需时24天左右。用这种方法提前育苗比在露地直接栽苗有如下优点: 1.苗木的成活率高。我们在1985年春育苗两次,苗育到5—10厘米高时,第一次成活率达98％,耗时26天;第二次成活率达95％,耗时22天。育苗期间,大田里司以进行开沟、换土、施肥、也可种一茬春菜。定植时将塑料袋撕破,将苗放入定植穴(沟)内,踏实后浇水,成活率可达100％,且不缓苗。 2.能抵御低温,促进葡萄苗健壮生长。在北方寒冷地区,采用此法可在塑料大棚、温室内育苗,待 Chongli County, Hebei Province, Gaojiaying Township Wulahada village forestry team, to increase the field planting grapes to achieve the year planted seedlings, then put the article, the purpose of the next year results. In the plastic shed with plastic bags to cultivate Kyoho grape seedlings success. The average survival rate of 95.5%, 5-10 cm tall, takes about 24 days. In this way nursery earlier than in the open planted directly has the following advantages: 1. Seedling survival rate. We raised nursery twice in spring 1985, when nurturing to 5-10 cm high, the first survival rate of 98%, took 26 days; the second survival rate of 95%, took 22 days. During nursery, Ota Division to conduct ditching, soil replacement, fertilization, but also a kind of spring vegetables. Plastic bags will be torn when planting, the seedlings into the planting hole (ditch), practical watering, the survival rate of up to 100%, and not Huanmiao. 2. Can withstand low temperature, promote vigorous growth of grape seedlings. In the northern cold areas, using this method can be plastic greenhouse, greenhouse nursery, to be
