| 摘 要： | 为探究大田茄子地下渗灌管的适宜埋深和灌水定额,田间试验布置了3个不同渗管埋置深度(0、10、20 cm)和3个不同灌溉水平(1750、2250、2750 m^3/hm^2),研究地下渗灌不同埋深和不同灌溉定额对大田茄子生长发育、产量和水分利用效率的影响。结果表明,埋管深度为10 cm,灌溉定额为2750 m^3/hm^2处理下茄子产量和干物质积累量最高;埋管深度在10 cm,灌溉定额为2250 m^3/hm^2处理下,茄子水分利用效率最高,产量次之。综上可见,在宁夏引黄灌区气候条件下,地下渗灌最佳埋设深度为10 cm,相应灌溉定额为2250 m^3/hm^2。

| Abstract: | In order to explore the suitable buried depth and irrigation quota for underground infiltration irrigation of field eggplant,in the field experiment,three different buried depths(0,10 and 20 cm)and three different irrigation levels(1750,2250 and 2750 m^3/hm^2)were arranged to study the effects of different buried depths and irrigation quotas on the growth and development,yield and water use efficiency of field eggplant.The results showed that the eggplant yield and dry matter accumulation were highest under the treatment of 10 cm buried pipe and irrigation quota of 2750 m^3/hm^2;the eggplant water use efficiency was highest under the treatment of 10 cm buried pipe and irrigation quota of 2250 m^3/hm^2,followed by production.In summary,under the climatic conditions of the Yellow River Irrigation Area in Ningxia,the optimal buried depth of subsurface infiltration irrigation is 10 cm,and the corresponding irrigation quota is 2250 m^3/hm^2. |
