秋季造林,苗木要经过严寒的冬季和干旱的春季,损失水分较多,容易死亡。实践证明,采用防寒防旱的造林措施,是确保苗木成活的关键。具体作法因树种而异。栽油松要“窄坑、靠壁、随栽随埋”油松是辽西干旱地区造林的主要树种之一,秋季栽植要先刨好横山长22厘米、宽12厘米、深22厘米两壁直立的长方形窄坑,然后将合格的2年生苗紧贴垂直壁中间放好(阴坡靠上壁,阳坡靠下壁),不要窝根,填少半坑土后,每穴再浇水2斤(土湿能握成团时可不浇
Fall afforestation, seedlings to go through the cold winter and dry spring, loss of water more, easy to die. Practice has proved that using cold and drought afforestation measures to ensure the survival of seedlings key. Specific practices vary by species. Pinus tabulaeformis “narrow pit, by the wall, with the planted with buried” Pinus tabaci is one of the main afforestation species in arid areas in western Liaoning, the first planted in autumn planed good Hengshan 22 cm long, 12 cm wide, 22 cm deep and two walls upright Rectangular narrow pit, and then the qualified 2-year-old close to the middle of vertical wall put aside (shady by the upper wall, the sunny slope by the next wall), do not nest root fill less half pit soil, and then watering each hole 2 Kg (soil moisture can not hold into a group can be poured
