春季是造林的大好季节。我国北方春季造林的适宜时期,一般从土壤解冻十几厘米开始,至苗木冬芽将萌发时结束。就内蒙古大部分地区而言,春季造林适宜时间,每年不过十来天。超越这段时间,早了,土壤还在冻结中,起苗、挖坑、栽植等工序效率低而质量差;晚了,苗木冬芽萌发,造林成活率显著降低。很显然,我区春季可供利用的造林时间短而集 Spring is a good season for afforestation. The appropriate period of afforestation in the north of our country in spring generally begins with thawing a dozen centimeters of soil, and when the winter bud of seedlings will germinate, it will end. In most parts of Inner Mongolia, afforestation in spring is suitable for time, but ten days a year. Beyond this period of time, early, the soil is still frozen, lifting, digging, planting and other processes inefficient and poor quality; late, seedling winter buds, afforestation survival rate significantly reduced. Obviously, the planting time available for use in spring in our region is short and the collection time is short
