虎什哈林场位于承德市虎什哈镇三道河村,这里地处辽、蒙交界,气候条件恶劣,春季干旱少雨,冬季大风寒冷,林地地质主要由河滩沙石构成。笔者经过调查实践,对虎什哈林场特殊环境条件下育苗技术进行了总结。1育苗地的选择育苗地要选择地势平坦,灌水排水方便,土壤肥沃的砂质土壤或壤土,地下水要在1.5m以下,土壤过于粘重或盐碱化严重的地块,需经改良后方能用作育苗地。虎什哈苗圃由于土壤瘠薄,营养成分少,主要通过向沙石地混合山地土,培土治沙,改良土壤,培肥地力。
Huxha Hulin Farm is located in Sandaohe Village, Hu Shishu Town, Chengde City. It is located in the border of Liao and Mongolia where the weather conditions are harsh. In spring, it is arid and dry. The winter gale is cold, and the forest land is mainly composed of beach sand and gravel. After investigating and practicing, the author summarizes the seedling raising technology under special environmental conditions in Huxishu Forest Farm. A selection of nursery grounds Nursery to choose flat, easy irrigation and drainage, fertile sandy soil or loam, groundwater should be below 1.5m, the soil is too viscous or salinized land mass, subject to improvement before Used as a breeding ground. Because of soil infertility, Huzheha Nursery mainly mixes mountainous soil with sand and gravel so as to control soil erosion, improve soil and fertilize soil fertility.
