春季造林早点动手好,而且最好在大地刚解冻到能栽入苗根的深度时就进行。因为这时大地虽然解冻,但气温并不高,而且土壤水分蒸发量不大,土壤是既松软又湿润,同时,这时落叶树无叶,常绿树新芽尚未萌发,苗木本身的水份蒸发量也不大,从土壤条件到苗木本身条件,都有利于苗木的成活。再说,这时栽上是先长根后发芽,等到发芽时,根条已能够吸收土壤中的水分和养分,满足枝叶生长的需要。还有,这时
Afforestation is good early in the spring, and is best done when the earth has just thawed to the depth where it can be planted. Because at this time the earth is thawed, but the temperature is not high, and soil moisture evaporation is not large, the soil is not only soft and moist, at the same time, at this time deciduous trees without leaves, evergreen sprouts have not yet germinated, seedlings moisture evaporation Not large, from the soil conditions to the conditions of nursery stock, are conducive to the survival of nursery stock. Moreover, when planted at this time is the first root after germination, until germination, the root has been able to absorb soil moisture and nutrients to meet the needs of the growth of branches and leaves. Also, at this moment
