| 摘 要： | 研究了大田玉米在非充分灌溉条件下,不同栽培模式对土壤水分、产量及其构成要素的影响。结果表明,全膜垄侧栽培、全膜垄沟、全膜双垄模式均能提高0～10cm土层的土壤含水率。主要生育期(抽雄期除外)内,全膜垄沟栽培模式土壤含水率高于其他处理。全膜垄沟栽培模式在苗期—大喇叭口期内耗水强度较低,但产量和水分利用效率最高,分别为17 153.91kg/hm2和37.59kg/(hm2.mm),具有显著的节水增产效应。 |

The Effects of Different Cultivation Modes on Maize Yield and Soil Water under Deficit Irrigation |
|
| Abstract: | The effects of different cultivation modes on soil water,maize yield and yield components under deficit irrigation were studied.The results showed that the ridge side of the whole film cultivation,furrow of whole film,the double ridge pattern of the whole film could significantly improve the content of soil moisture in 0～10cm soil layer.Compared to those in other treatments,soil moisture in different maize growth periods(except the heading stage)was higher.Water consumption intensity of seeding stage～big trumpet stage was lower,but maize yield(17 153.91kg/hm2)and WUE(37.59kg/(hm2.mm))were higher under the whole film furrow.So it has a significant water-saving effect under the whole film furrow. |
