摘  要:
以矮化密植"工藤富士"苹果树为研究对象,通过大田滴灌和痕量灌溉对比试验,研究2种不同灌溉方式及痕量灌溉2种不同灌水定额下,果园土壤水分的分布规律以及灌溉水的利用率,并结合果树实际水分需求,确定合理的灌溉方式、灌水定额、灌溉频率。结果表明:灌水量相等情况下,痕量灌溉的灌溉水利用率高于滴灌;苹果树痕量灌溉适宜的灌水定额为12L·株-1,流量0.2L·h-1,灌水频率约3~4d一次。

摘  要:
Taking ‘Kudo Fuji'apple tree as the research object,small-scaled water-saving irrigation experiments were conducted on fields and on a close-by apple orchard in August 2016.Examining two irrigation methods(drip irrigation and trace irrigation)parameters,such as soil water distribution,irrigation water use efficiency,and the amount of irrigation water were monitored.In order to establish an optimum irrigation regime the physiological water demand of trees was considered.The results showed that soil water distribution patterns varied by irrigation method and amount of irrigation water employed.Trace irrigation showed higher irrigation water use efficiency than in drip irrigation.Furthermore,the optimum irrigation regime of apple trees during August revealed to be trace irrigation with an irrigation quota of 12 Lper individual tree and an average water flow of 0.2Lper hour,irrigating once every three to four days.
