摘要
马铃薯是干旱地区主要粮食作物之一,水资源缺乏是制约当地马铃薯高产的主要因素。为探索干旱区马铃薯高效灌溉方式,通过田间试验,研究了不同灌溉次数和灌溉量对马铃薯产量和养分吸收的影响。结果表明,额定灌溉量2 250m^3/hm^2分10次灌溉可显著提高马铃薯产量和养分吸收量,对干旱地区节水节肥增效有重要意义。
Potato is the major food crop in arid area. The lack of water resources is the main factor restricting the high yield of potato. In order to explore the efficient irrigation method in arid area of potato growth, through field experiments, we studied the effect of different irrigation time and irrigation amount on potato yield and nutrient uptake. The results showed that the best irrigation amount is 2 250m3/hm2 and it should be divided into 10 intervals to significantly increase crop yields and nutrients uptake. The result is of great importance to water and fertilizer efficiency in arid area.
