【摘要】 为解决稻田泡田水资源过度灌溉造成北方寒区水资源严重浪费和农业生态环境污染加剧的问题,以水稻田泡田水灌溉量满足正常搅浆平地作业为研究方法,进行了稻田泡田期不同旱整地作业模式泡田水灌溉量试验,研究不同旱整地技术模式对泡田水用量和产量性状的影响。研究结果表明,秋翻地旋耕技术模式能有效减少泡田期灌溉水用量和插秧期稻田排水量,提高水稻产量和产量影响因子指标。秋翻地旋耕技术模式泡田期灌溉量为1 613. 3 t/hm~2,较未翻地原茬泡田处理和秋翻地处理泡田水节约率分别为33. 3%和27. 3%。插秧排水量为38. 3 t/hm~2,较未翻地原茬泡田处理和秋翻地处理泡田水减少排放量分别为0. 0 t/hm~2和506. 7 t/hm~2。水稻产量为9 258. 6 kg/hm~2,与未秋翻地原茬泡田处理和秋翻地泡田处理相比较,增加产量3. 8%和1. 7%。秋翻地旋耕旱整地技术模式是本研究的最佳模式,为我国北方寒区水稻节约水资源和减少环境污染提供了新途径。更多还原

【Abstract】 In order to solve the problem of serious water waste in the cold regions of northern China and the aggravation of agricultural ecological environment pollution in order to solve the problem of over-irrigation of water resources in paddy fields in paddy fields,the rice paddy field irrigation amount satisfies the normal agitation leveling operation as a research method. To study the effects of different dry land preparation techniques on the water consumption and yield traits of paddy field in different paddy field operation modes in paddy field in paddy field. The results show that the rotary tillage technology model can effectively reduce the amount of irrigation water in the paddy field and the displacement of paddy field in the transplanting stage,and increase the yield factor index and yield of rice yield. The irrigation amount of the rotary tillage technology model in the autumn is 1 613. 3 t/hm~2,the water saving rate of the paddy field treatment was33. 3% and 27. 3%,compared with the unflooded field and the autumn field treatment; the transplanting displacement was 38. 3 t/hm~2,which was compared with the unexpanded ore field and autumn. The reduction of the discharge of the paddy field water treatment was 0. 0 t/hm~2 and 506. 7 t/hm~2; the rice yield was 9 258. 6 kg/hm~2,which was increased compared with the treatment of the uncultivated field and the autumn field. The yield is 3. 8% and 1. 7%. The technical model of rotary tillage and land preparation in autumn is the best mode of this study,which provides a new way for rice in northern cold regions to save water resources and reduce environmental pollution.更多还原
