近年来,北京地区栽植葡萄的面积不断扩大。我场由原来的2,450亩,扩大到4,500亩,增加面积50%。但因在北京地区种植不抗寒的玫瑰香葡萄品种,其植株冬季必须进行埋土防寒方能安全越冬,所以也影响葡萄生产的发展和提高。葡萄植株的埋土防寒不仅费工费力、劳动强度大,而且易损伤枝蔓和根系,影响葡萄植株的正常生长发育和产量提高。我场每年因葡萄植株埋土防寒而损伤的枝蔓都在5%以上,有时高达10%,产量损失达十几万斤。因此,葡萄植株的埋 In recent years, the area planted with grapes in Beijing continues to expand. My field from the original 2,450 acres, expanded to 4,500 acres, an increase of an area of ​​50%. However, due to the cultivation of non-cold hardy grape varieties in Beijing, its plants must be buried in winter to be safe and wintering in winter so that the development and enhancement of grape production will also be affected. Buried vine grape cold hard time, labor-intensive, and easy to damage branches and roots, affecting the normal growth of grape plants and yield. My field every year due to grape plants buried cold and damaged branches are more than 5%, sometimes as high as 10%, the yield loss of more than ten kilograms. Therefore, grape plants are buried
