近年来,各地新栽山楂幼树较多,但 存在成活率不高问题,为此提出新栽山楂 幼树成活率的主要技术措施,供参考。 1、选择优质苗木:这是提高成活率 的关键环节。优质苗木的标准是:接口部 以上苗高超过1米,粗度(地径)在0.8厘 米以上,枝条充实,芽子饱满,无病虫害; 具有20厘米长以上的
In recent years, there are a lot of young hawthorn trees planted everywhere, but there is a problem of low survival rate. Therefore, the main technical measures for the survival rate of young hawthorn saplings are proposed for reference. 1, choose high-quality seedlings: This is to improve the survival rate of the key link. The standard of high-quality seedlings is: the interface above the seedling height of more than 1 m, the roughness (diameter) at 0.8 cm or more, branches full, bud full, no pests and diseases; with more than 20 cm long
