【摘要】 为提高麦田水分利用效率,实现农艺节水,试验对小麦无垄栽培均匀种植和传统条播2种种植方式麦田的水分利用情况进行监测,苏正研发基地无垄联合耕播机示范区的试验结果表明,与小麦传统条播相比较,小麦无垄栽培水分利用效率提高了24.19%,产量增加了14.23%;吴桥试验站蒸渗仪试验结果表明,小麦无垄栽培全生育期耗水量较传统条播减少了1.49%,亦具有节水效果;通过对2种种植方式投入情况的调查,结果显示,小麦无垄栽培均匀种植技术与传统条播相比可节支712.5元·hm-2。综合说明,小麦无垄栽培均匀种植技术是北方干旱地区一种适宜的种植方式。更多还原

【Abstract】 The experiment was conducted to improve the water use efficiency and achieve agricultural water conservation in the wheat field, the water use indices of two kinds of planting methods including the uniform planting without ridges and the traditional sowing were monitored. The results of the demonstration area of the no-ridge joint cultivator in Suzheng’s research and development base showed that, compared with the traditional sowing method, the water use efficiency and the yield of wheat without ridge increased by24.19 % and 14.23 %, respectively. The results of the evaporator test at Wuqiao test station showed that the total water consumption during the whole growth period of wheat without ridge cultivation decreased by 1.49 % compared with the traditional strip sowing, indicating that the uniform planting without ridges had water-saving effect. According to the input investigation of the two planting methods, the results showed that the uniform planting technology of ridgeless cultivation of wheat could save 712.5 RMB· hm-2 compared with traditional strip sowing. In conclusion, the uniform planting technique of wheat without ridge could be a suitable planting method in arid areas of north China.更多还原
