埋土越冬露地栽培法 采用两年以上树苗,沟栽矮化密植,冬季修剪地上枝后埋土护根露地越冬。苗木定植一般采用沟宽1.2米,株距20厘米,每亩栽苗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。采芽时留1-2个新叶,不可将整芽掰下。留下的新叶叶腋处过20天又萌发出二次侧芽。
Buried winter planting methods used more than two years of saplings, dwarf dense ditch planting, pruning the ground in winter after the roots buried buried open-air winter. Planting seedlings generally use groove width 1.2 meters, spacing 20 cm, planted 2700 plants per acre, irrigation immediately after planting, and then set at the surface of 20 cm at the dry pruning. Toon tree top edge is very strong, generally only sprout 1-2, when the bud grows to about 10 cm, began to sprout. Leave 1-2 new leaves when collecting buds, not to break off the whole bud. Leave a new leaf axils after 20 days and secondary germination of secondary buds.
