中耶尔根尼丘陵和萨尔平低地森林植物条件的特点是土壤严重缺水,碱土的物理—化学特性不利于植物的生长;年平均降雨量约为250毫米,比当地水面的蒸发量少3/4,经常发生旱风和尘风暴。耶尔根尼丘陵地区土壤缺水问题可以采用农业技术措施解决,如深耕、休间、设置拦雪栅、断续开沟等。而萨尔平低地土壤缺水问题可以利用当地逕流灌溉解决。碱土的不良物理—化学特性可采用下述各项
The conditions of forest plants in the Middle Hilly Genghisand Salping Lowlands are characterized by severe soil water deficit and the physico-chemical properties of alkaline earths are not conducive to the growth of plants. The average annual rainfall is about 250 mm, less than the evaporation from the local surface 3/4, frequent dry winds and dust storms. The problem of soil water shortage in the Yergenhin hills can be solved with agricultural techniques such as deep plowing, rest breaks, setting of snow barriers, intermittent ditching and so on. However, the problem of soil water shortage in the Salping lowlands can be solved by using local runoff irrigation. Adverse physical-chemical properties of alkaline earth The following items can be used
