在我省栽培葡萄,最好栽植用山葡萄作砧木的嫁接苗。嫁接成苗不足时,可采用先定植山葡萄苗,第二年就地嫁接的方法建园。这种方法由于首先扩大了根群,所以嫁接上栽培品种后能迅速生长成形并很快进入高产期。因此,要建园,必须首先大量繁育山葡萄砧木苗。近年来,我省各农场、果园播种的山葡萄籽总计均在千斤以上,但成苗量却很少。什么原因呢?主要是管理不当、以及不能有效地控制霜霉病的为害所造成的致使幼苗枝蔓不能成熟。越冬后大量被冻死,存活的苗木细弱质量很差。那么,怎样繁育山葡萄呢?要掌握好以下几个关键环节:
Grape cultivation in our province, the best planting grapes with grapes as a rootstock grafting. Grafting seedlings inadequate, can be the first planted planting grapevine Hill, the second year in situ grafting method Park. This method, due to the first expansion of the root group, so after the cultivation of grafted varieties can quickly grow into shape and quickly into the high yield. Therefore, to build a garden, we must first large-scale breeding grapevine Hill seedlings. In recent years, the province of all farms, orchards sown mountain grape seed total of more than pounds, but the amount of seedlings is very small. What is the reason? Mainly improper management, and can not effectively control the damage caused by downy mildew caused by seedlings can not mature. After a large number of winter was frozen to death, the survival of the delicate quality of seedlings is poor. So, how to breed mountain grapes? To master the following key links:
