内蒙古盛乐经济开发区植物生长供水影响因素研究

A Study on Factors of Water Supply to Plant Growth in Shengle Economic Development Area in Inner Mongolia

对内蒙古盛乐经济开发区影响植物生长供水的因素进行研究.结果表明,研究区的降水量随时间分配不均匀,蒸发量较大;其土壤性质为砂壤,蓄水能力较差;降水补给较少,对植物生长不利.特别是生长季降水较少,很难满足种植植物的需水量.指出在该区今后的绿化过程中,一方面要挖掘灌溉水源,另一方面要注重引进耐旱植物品种,以降低降水不足、蒸发量大、土壤保水性能差等不利影响.

The factors of water supply to plant growth in Shengle economic development area were studied. The results showed as follow： the precipitation distributing is asymmetric and the evaporation is remarkably big; the character of the soil is sandy which has low ability to hold water; the replenishment of the precipitation to the soil is limited,which is disadvantageous to the plants growing. The precipitation is small and difficult to satisfy the demand water of the plant especially in growth season. So in future, the water source should be digged and the arid resistant plant be introduced.
