赤峰市郊区国营安庆沟苗圃是1973年在风积沙地上建立起来的。苗圃地的土壤肥力差,透水性强,持水性差,肥力容易跑失。过去苗圃培育松苗,多采用大水漫灌方式,效果很不理想,既费土地,又费水。灌水次数少了,水量不足,苗木缺水,地温升高容易发生病虫害;灌水次数多了,水量增大,但地温随之降低,土壤中的肥份也容易随水跑掉。这样,几年来培育的落叶松、樟子松和油松总是缺苗断条,生长也参差不齐,产量低,质量也差,成本却很高。
Anqinggou nursery in the suburban area of Chifeng City was established on aeolian sand in 1973. Soil fertility nursery to poor, water permeability, poor water holding capacity, fertility easy to run away. Nursery seedlings nurturing the past, the use of large flood irrigation methods, the effect is not ideal, both the land costs, and water. Less irrigation times, insufficient water, seedlings water shortages, prone to pests and diseases increased ground temperature; irrigation times more, the water increases, but the ground temperature decreases, soil fertility is also easy to run away with the water. In this way, larches, Pinus sylvestris and Pinus tabulaeformis cultivated in recent years are always lack of seedlings broken, growth is also uneven, low yield, poor quality, but the cost is high.
