摘要
根据 1996年～ 1998年陕西省淳化县泥河沟流域试验区田间试验资料研究了在小管出流灌水条件下 ,苹果耗水量与产量、质量的关系 ,根据苹果全生育期水量平衡原理 ,确定耗水量 ,并结合理论公式推算不同频率年的耗水规律 ,分析确定了最佳耗水量与最佳灌溉定额 ,最后提出渭北地区苹果高产的灌溉制度 :灌水定额 330 m3 / hm2 ,灌水次数最多 8次 ,最少 1次。
Based on field experiment during 1996 and 1998 conducted in Nihegou watershed of Chunhua county Shaanxi Province, the relationship between water consumption and yield as well as quality of apple under the condition of micro pipe irrigation were studied. The optimal water consumption and irrigation norm were analyzed and determined by using theoretic formulation and water balance principle at growth season. Finaly, high yielding irrigation schedule, suitable to this area for apple trees was suggested: irrigation norm is 330 m 3/hm 2 per time. The most is 8 times and the lest is 1 time.
