摘要
通过开展不同地下水埋深条件下冬小麦和玉米全生育期潜水蒸发试验,探讨浅埋深地下水对作物生长规律的影响,为地下水浅埋区制定灌溉制度提供参考。试验结果分析表明,不同埋深的地下水对作物的生长发育过程有着很大影响,根系生长在分蘖期和拔节期受地下水位影响较大;而冠的生长则是在孕穗期到灌浆期影响较明显;作物的腾发量也不同。
The groundwater evaporation experimentation of the winter wheat and corn considering the influence of shallow groundwater is established, which is helpful for controlling of crops growth. Based on the describing of experimentation results, the quantitative growth laws responding to different shallow groundwater both for root and shoot are revealed. It is found that water table affects the growth of root remarkably during tillering and jointing stage and affects the growth of shoot during booting and grouting stage and affects the evapotranspiration of the plant.
