程海湖滨区造林的土壤条件分析及其应用技术

Soil Condition Analysis and Application Technology of Forestation at Sides of Chenghai Lake

通过对程海湖滨区土壤条件的分析,针对其造林困难的特点,经试验研究提出了适用于该区域的造林技术措施。分析认为:程海湖滨区多为塌陷松散堆积物,土壤石砾含量高,达79.31%以上,土壤水分的渗透较快,既不保水也不保肥,在程海湖滨区采用优质容器大苗培育技术、大塘客土造林技术、旱季微渗持续给水灌溉技术,可取得较好的造林成效。

Through analyzing the soil conditions of lakesides of Chenghai Lake, aiming at the difficulty in forestation, some technical measures were proposed on the basis of experimental study. The results of analysis indicated that the sides of Chenghai Lake were mostly covered with loose sediment, the percentage of stone and gravel was high as 79.31% or above, the soil water penetrability was big, not good for both water and fertilizer preservation. In forestation experiments, using quality big size container seedling, soil replacement, big planting pit, seep-bose irrigation system in dry season, good forestation effect was achieved.
