摘要
以"北农佳秀"黄瓜为试材,研究了不同灌溉方式对其生长、产量、经济效益和水分生产效率的影响,以期明确不同灌溉方式节水增产效果。结果表明:膜下微喷和膜下滴灌均能促进黄瓜生长,提高产量、灌溉水分生产效率、品质和经济效益。与CK(覆膜沟灌,农户常规灌溉量)相比,D1(膜下滴灌,70%常规灌溉量)、D(膜下滴灌,85%常规灌溉量)、M1(膜下微喷,70%常规灌溉量)和M(膜下微喷,85%常规灌溉量)产量分别提高34.5%、33.4%、29.1%和21.4%,处理差异显著。经济效益分别增加3.53万、3.31万、3.27万、2.20万元/hm2。在该试验条件下,综合产量、水分生产效率和经济效益等指标,建议条件较好的农业园区采用滴灌技术,生产条件相对较差的地区采用膜下微喷技术。
Taking cucumber‘Beinongjiaxiu＇as material,the effect of irrigation methods on the growth,yield,economic benefits and irrigation water use efficiency of plastic house cucumber were analyzed.The results showed that the plant growth,yield,quality and water use efficiency of micro jet under mulching and drip irrigation under mulching were higher than traditional furrow irrigation.Compared with traditional furrow irrigation,the treatment D1,D,M1 and M,increased34.5%,33.4%,29.1%and 21.4%,economic benefits increased 35 300RMB/hm2,33 100RMB/hm2,32 700RMB/hm2 and 22 000RMB/hm2.In this experiment,integrated the properties of cucumber yiled,irrigation water use efficiency and economic benefits,agricultural park of better conditions to use drip irrigation under mulching,agricultural park of poor conditions to use micro jet under mulching were suggested.
