由于灌溉水源日趋紧张,灌溉成本越来越高,有必要确定省水且产量及品质适当的灌水量。Evans等(1960)以及Mac Kay等(1962)已证明在一定范围内的灌水量下甜玉米产量大致相同。甜玉米在吐丝期和雌穗发育初期不受水分胁迫时能获得较高的产量和较优的品质。本试验目的在于测定灌水量对甜玉米产量及品质的影响。由灌水最的范围可评价出亏水灌溉的影响。
Due to the increasingly tense irrigation water sources, irrigation costs are getting higher and higher, it is necessary to determine the water saving and yield and quality appropriate amount of irrigation. Evans et al. (1960) and Mac Kay et al. (1962) have demonstrated approximately the same sweet corn yields over a range of irrigation volumes. Sweet corn can obtain higher yield and better quality under the condition of silkworm and early stage of ear development. The purpose of this experiment was to determine the effect of irrigation on sweet corn yield and quality. The effect of water deficit irrigation can be evaluated by the range of irrigation.
