| 摘 要： | 通过田间试验,对宁夏中部干旱带旱地马铃薯水分亏缺补偿效应进行了研究.结果表明:以相同补水量在不同生育时期实施补灌,以块茎形成期和块茎增长期供水效率和产量最大;在块茎形成期以不同补水量实施补灌,在同时满足供水效率最高和产量最大的前提下,以3～4 kg/株的补灌量较适宜.旱地马铃薯在最佳补灌时期实施适量补灌,能够实现节水、增产和高效用水的目的.

| Abstract: | Field trials are conducted to study water deficiency and compensation effect and the calculus regressive function of complementary irrigation and yield of potato in the arid area in central Ningxia.The results show that,as for the same irrigation amount,tuber initiation and bulking stages are the stages of complementary irrigation with the most yield increase and water supply efficiency;using different irrigation amount at the tuber initiation stage,both the yield and water supply efficiency are the largest... |
