在发展葡萄生产中,确定适栽品种和栽植密度后,如何才能使建园当年全苗壮苗,为早期丰产打下基础?为此,我们结合一九八四年在延津县建一千亩示范园,对此进行了探讨。实践表明,要达到建园当年全苗壮苗的目标,须做好以下各项技术措施。一、正确确定栽植时期延津冬季、早春寒冷,雨雪少强风多,相对湿度低,天气多变,土壤沙性蓄水保水力弱。秋、冬、早春栽苗建园易受冻害,抽条,因此不能确保高的成活率。实践证明:葡
In the development of grape production, to determine the suitable planting varieties and planting density, how can we make the whole year seedling stronghold seedling garden, laying the foundation for the early harvest? To this end, we combined with one thousand acres built in Yanjin County in 1984 Demonstration Garden, which discussed. Practice shows that in order to achieve the goal of establishing a strong seedling seedlings in the current year, the following technical measures must be taken. First, the right to determine the planting Yanjin winter, early spring cold, snow less strong winds, relative humidity is low, the weather is changing, the soil is weak sandy water retention. Autumn, winter and early spring planting seedlings built vulnerable to frost damage, pumping, it can not ensure high survival rate. Practice shows that: Portugal
