一、埋土越冬露地栽培法采用两年生以上树苗,沟栽矮化密植,冬季修剪地上枝后埋土护根露地越冬。苗木定植一般沟宽1.2米,株距20厘米,每667平方米栽苗2700株,定植后立即灌水,随后在地表20厘米处定干修剪。香椿树顶端优势很强,一般只萌芽1～2个,当芽长至约10厘米时,开始采芽。采芽 First, the buried winter planting methods used more than two years of saplings, dwarf dense planting ditch, pruning the ground in winter after the branches buried roots exposed wintering. Seedling planting width of 1.2 meters in general ditch, plant spacing 20 cm, planted seedlings per 667 square meters 2,700 plants, irrigation immediately after planting, and then set at a dry surface 20 cm at the pruning. Toon top edge of the tree is very strong, usually only sprouting 1 to 2, when the bud grows to about 10 cm, began to sprout. Collect buds
