一、适时栽植 栽植林木及果树应在落叶后萌芽前进行。此期苗木处于休眠期,体内贮藏养分较多,蒸腾量较小,根系易恢复生长,故栽后成活率高。黄河以北,冬季严寒,冻土层深,秋植易发生“抽条”或枯死,以春季栽植比较适宜。 二、春季早栽 林木及果树在休眠状态下栽植,随土壤返浆和气温回升,有利于苗木萌动,同时根系的再生能力强,伤口愈合快,缓苗时间短。所以,早春是栽树的最佳时期,时间以土壤地冻后立即进行为宜。
First, timely planting planted trees and fruit trees should be carried out before deciduous. Seedling dormancy in this period, the body more storage of nutrients, less transpiration, the root system easy to resume growth, so after transplanting survival rate. To the north of the Yellow River, the winter is cold, the permafrost layer is deep, the autumn planting is prone to “drawing” or withering, and the planting in spring is more suitable. Second, early spring planting trees and fruit trees planted in dormant state, with the soil back to pulp and temperature rise, is conducive to germination of seedlings, while root regeneration ability, wound healing fast, Huanmiao time is short. Therefore, early spring is the best time to plant trees, the time to soil immediately after freezing is appropriate.
