高寒旱地山区玉米全膜双垄种植技术节水效益研究

针对青海省高寒干旱山区农业生产中水资源不足、春夏干旱突出等问题,设计玉米全膜双垄栽培技术种植方式研究。结果表明,与传统裸地种植春小麦的水分生产效率和水分生产效益进行对比,全膜双垄栽培技术由于显著改善了土壤的水、温状况,从而促进了玉米的生长发育,大幅度提高了单位面积产量和单位面积效益,增产幅度达197%。

Study on the Water Saving Benefits of All Membrane Double Ridge Culture Technology in the Alpine and Arid Mountainous Areas

Due to inadequate water resources and prominent spring and summer drought during the agricultural production in the alpine and arid mountainous areas of Qinghai Province,the study of a planting method is applied in corn. All membrane double ridge culture technology was designed. Results showed that compared with the water production rate and moisture productive benefit of the traditional planting of spring wheat in bare fields,all membrane double ridge culture technology promoted the growth and development of the corn because of the significant improvement of the water and temperature conditions of the soil.Since of the utilization of this planting method,the per unit yield and per unit area benefits were substantially increased,which was up to 197%.
