| 摘 要： | 通过在额尔齐斯河流域阔斯持克乡的实验．分析其现行灌溉方式对作物需水量的满足程度。结果表明现行灌溉制度与灌溉方式虽然可以满足作物需水．但灌水定额量很大，而土壤蓄水能力有限，灌溉水量的2／3以上成为余水或深层渗漏，在大豆生长后期存在灌水过多现象。 |
| 关 键 词： | 作物需水量 薄土层 土壤水分观测 评价 |

| Abstract: | Based on the field experiment at the Kousiteke Country in the Eerqisi River Basin, the degree of the needs of the crop water requirement is analyzed under the current mode of the irrigation. The results show that the current system and the mode of the irrigation can meet the needs of the crop growth, but the irrigation is too much in the condition of the limit to the soil water storage, so more than 2/3 irrigation is infiltrated into the deep soil layer.And there is the phenomenon that the irrigation is more in the later period of the soybean growth. |
| Keywords: | crop water requirement thin soil layer soil moisture observation evaluation |
