| 摘 要： | 利用农田水量平衡公式计算了冬小麦耗水量,用微型蒸渗仪测定了农田土壤棵间蒸发状况,在此基础上通过对比试验研究了土壤扩蓄增容肥条件下不同水分处理冬小麦生长期间农田棵间蒸发与水分利用效率.结果表明,施加土壤扩蓄增容肥后冬小麦生育期平均耗水量较对照平均减少了491.67 m3/h㎡,可明显降低冬小麦棵间蒸发,同时可降低播种到拔节期阶段棵间蒸发占阶段耗水量的比例;灌水量2250 m3/h㎡3理(T2)水分利用效率达2.62 kg/m3;灌水量1950 m3/h㎡的处理(T3)可增产32.68%. |

| Abstract: | Through contrast experiments,soil evaporation and water use efficiency of winter wheat after applying soil amendment fertilizer were studied using the method of farmland water balance and micro-lysimeter. Results indicated that after applying soil amendment fertilizer,the mean water consumption of winter wheat during the growth period decreased by 491.67 m3/hm2 averagely,compared with the contrast. Soil evaporation of winter wheat and the ratio of soil evaporation to water consumption during the stage from seeding to jointing also decreased. The water use efficiency was 2.62 kg/m3 under the treatment of 2 250 m3/hm2 irrigation water and the yield increased by 32.68% under the treatment of 1 950 m3/hm2 irrigation water. |
