我国大部分地区造林时间,一般是在2月底至4月中旬。此时气温低,风速小,雨水多,阳光弱,苗木尚未萌动,宜于栽植。造林季节一般应根据当地的气候条件选择;春季在4月中旬期间土壤解冻后进入返浆期,要抓住这一时期,适时早栽,此时苗木地上部分还未生长,而根系已经开始活动,早栽的苗木先生根后发芽,蒸腾作用小容易成活,有利于提高苗木成活率和增强抗性;秋季应在10月中旬~11月上旬之间土壤封冻以前,此时气温逐渐下降,土壤水分比较稳定,苗木落叶,地上部分蒸腾减少,苗木生理活动减弱,栽后容易恢复生机,来春苗木生根发芽早,有利于抗旱。下面根据实践经验,谈谈造林技术。
Afforestation in most parts of China, usually in late February to mid-April. At this time low temperature, wind speed, rain, weak sunlight, seedlings have not yet sprouted, should be planted. Afforestation season should generally be based on local climatic conditions to choose; Spring in mid-April after thawing into the soil back to the pulp, to seize this period, early planting at this time, at this time the seedling has not yet part of the ground, while the root system has begun activities , Early planting seedlings root germination, transpiration is easy to survive, is conducive to improving seedling survival rate and enhance resistance; autumn should be in mid-October to early November before freezing the soil before, when the temperature gradually decreased soil Moisture is relatively stable, seedlings deciduous, transpiration decreases on the ground, seedling physiological activity weakened, easy to restore vitality after planting, spring seedlings germinate early, is conducive to drought. The following based on practical experience, talk about afforestation technology.
