我区葡萄栽培历史较久,面积较大。从当前几个主要产区的生产来看,普遍不能充分成熟,因而品质差,如:果穗松散、果粒不整齐、青粒比率大、含酸多、着色不匀等,这就降低了商品销售价格,严重影响了生产单位的经济收益。造成上述问题的主要原因是我区生长季比较短,有效积温低,不能满足某些品种生长发育的需要。 My region viticulture history longer, larger area. Judging from the current production of several major producing areas, they are generally not sufficiently mature and thus have poor quality, such as loose ears, irregular fruit grains, large proportion of green grains, rich acidity, uneven coloring and the like, which reduces the amount of goods The selling price has seriously affected the economic benefits of the production units. The main reason for the above problems is that the growing season in our region is relatively short and the effective accumulated temperature is low, which can not meet the needs of growth and development of some varieties.
