“三北”地区，春季多风少雨、蒸发量大，年年春旱，严重影响着各种果树的栽植成活率。多年来通过对核桃、苹果、花椒、山杏等果树改春栽为秋栽，大大提高了成活率，并缩短缓苗期。进而对仁用杏进行秋栽试验，并大面积推广，成活率达到９５％—９８％，且生长快，是春栽成活率? In the “Three Norths” region, windy and rainy spring, large amount of evaporation and spring drought year by year severely affected the survival rate of various fruit trees. Over the years through the walnut, apple, pricklyash, apricot and other fruit trees planted autumn planting for autumn, greatly improving the survival rate and shorten the hurried seedling stage. And then the autumn planting apricot test, and large-scale promotion, survival rate of 95% -98%, and fast growth, is the spring survival rate?
