摘要
根据榆中县东部半干旱农业区的特点,总结推广的旱作玉米双垄全膜覆盖集雨沟播集成技术模式可使旱地玉米平均单产比半膜覆盖增产30.4%,增加产值2345.4元/hm2;小麦微垄覆膜集雨集成技术模式可使旱作小麦的平均产量比露地常规种植对照增产25.2%,增加产值758.25元/hm2。并重点从选地整地、选用良种、起膜覆膜、田间管理等方面介绍了配套栽培技术。
According to the weather characteristic of semi-arid agricultural area in east part of Yuzhong county,the yield of extend maize cultivar which fit to arid area by using the integrated cultivation technology of double ridge,plastic film covered completely,rainwater using and sow in furrow increased 30.4% compared to the one of using cultivation technology of half plastic film covered.The value of output improved RMB 2 345.4 yuan/hm^2,too.To the wheat,the yield increased 25.2% by using the same technology compared to the average cultivation,and the value of out improved RMB 758.25 yuan/hm^2.The article also introduced the relative cultivation technology of land selection and preparation,improved cultivar selection,plastic film covering,field management.
