落叶松具有造林成活率高,生长快,耐寒,抗干旱的特性。我旗十年生的华北落叶松高达四米,近年平均高生长量达九十厘米。由于生长快,适应性强,移栽容易成活,树干通直,材质优良,适合高寒干旱山地造林,已成为我旗山区公社重点造林树种之一。由于高寒干旱地区,气候恶劣,无霜期短,生长期九十天左右,春季干旱多风,冬季严寒达零下35℃以下,给落叶松育凿带来很多困难。经过多年实践,已初步掌握高寒干旱地区落叶松育苗技术特点,使落叶松育苗达到二年出圃,每亩产苗8—10万株。那日斯太国营 Larch has afforestation survival rate, fast growth, cold, drought-resistant characteristics. The perennial Larix principis-rupprechtida, with its flag of up to four meters, grew by an average of 90 centimeters in recent years. Due to its rapid growth and adaptability, transplanting is easy to survive. The tree trunk is straight and the material is good. It is suitable for alpine and arid mountainous afforestation and has become one of the key afforestation species in the commune of Chishan County. Due to the arid and arid regions, the weather is bad, the frost-free period is short, the growth period is about 90 days, the spring winds are arid and the winter cold is below minus 35 ° C, which brings many difficulties to the lizards. After many years of practice, it has initially mastered the technical characteristics of larch seedling nurturing in the arid and arid regions so that the larch nursery seedlings reach the nursery for two years and produce 80,000 to 100,000 seedlings per mu.
