我省北方地区,冬季寒冷干燥,春季多风少雨,由于土壤湿度不够,地温较低,幼龄果树根系生理机能活动受阻,而地上部枝条蒸腾强烈,常造成抽条(旱垣地区更为明显).以往,1～2年生幼树常采用整株埋伏的办法防寒,效果很好,但3年生以上幼树所采用的筑防护篱、用秸秆或塑料条包扎的方法,费工费料,不适宜大面积推广.从1988年开始,我们用凡士林加熟猪油涂抹枝干防寒,取得了良好的效果. Northern region of our province, cold and dry in winter, spring windy and rainy, due to insufficient soil moisture, low ground temperature, physiological activity of young fruit tree roots blocked, and strong shoots shoots above the ground, often resulting in pumping (the more obvious In the past, 1 to 2 year-old saplings often use the whole plant ambush cold, the effect is good, but more than 3-year-old young trees used to build protective hedges, straw or plastic banding method, Not suitable for large-scale promotion. Since 1988, we use petrolatum plus lard coated sticks cold, and achieved good results.
