摘　　要：为了探究水肥互作对绿豆生长和产量的影响,制定适水减肥丰产的水肥管理制度指导绿豆生产,于2020年6—8月在河北省巨鹿县河北农业大学综合试验站开展田间试验。试验采用裂区设计,考虑灌水、施肥2个因素。通过控制绿豆不同生育期灌水上下限将灌水设3个水平,记为W1、W2、W3。追氮量设35、70和105 kg/hm^(2)3个水平,记为N1、N2、N3,并设不灌水不施肥处理作为对照组,记为W0N0。试验结果表明,不同水肥处理对膜下滴灌绿豆干物质积累影响差异明显,适当灌水施氮会延长绿豆的快速增长时间,增加其干物质累积最大速率。W2N2处理绿豆产量增加效果最好,与W0N0处理相比,增产65.5%。试验中W2N2处理绿豆生长良好,地上部干物质积累量较高,产量增加明显,达到1799.17 kg/hm^(2),故试验中W2N2处理的水肥组合是适用于黑龙港地区适水减肥丰产的水肥管理模式,可用于指导农业生产。In order to explore the impact of water and fertilizer interaction on mung bean growth and yield,the field tests were carried out from June to August 2020 at the Comprehensive Test Station of Hebei Agricultural University in Julu County of Hebei Province to formulate a reasonable water and fertilizer management system to guide mung bean production.The experiments adopted zoning design with two factors that were irrigation and fertilizer.The irrigation was set at three levels as Wl,W2 and W3 that were controlled between the upper and lower limits of irrigation in different growth stages of mung bean.The topdressing amount was set at three levels as 35 kg/hm^(2),70 kg/hm^(2)andl05 kg/hm^(2)that were recorded as Nl,N2 and N3.The treatment without irrigation and fertilization was set as the control group that was recorded as W0N0.The results showed that different water and fertilizer treatments had obvious effects on dry matter accumulation of mung bean under film drip irrigation.Increasing the amount of irrigation and nitrogen application appropnately could prolong the rapid growth time of mung bean and increase the maximum rate of dry matter accumulation.The W2N2 treatment had the best effect on increasing the yield of mung bean by 65.5%compared with WONO treatment.In the experiment,mung bean grew well under the W2N2 treatment.The aboveground dry matter accumulation was high,and the yield increased significantly as 1799.17 kg/hm^(2).Therefore,the water and fertilizer combination of the W2N2 treatment was suitable for Heilonggang area,which can be used to guide agricultural production.
