摘要
农田就地集雨栽培技术是促进旱塬地区创高产的重要途径,针对淳化县玉米窄膜覆盖技术产量和效益相对不高的情况,提出宽膜覆盖栽培技术,增加土壤含水量,提高水分利用率,并从经济效益方面进行了分析。结果表明:玉米宽膜覆盖栽培技术增产增收增效效果明显,为该项技术在全县大面积推广应用提供了依据。
The cultural technology of rainwater harvest in field is an important way to promote the crop yield in dry highland region.Based on the situation of low output of corn yield and benefit covering by the narrow film,the new cultural technology of covering field with wide film was put forward to increase soil water content and water use efficiency.The economic benefit of the technology was analyzed at the same time.The results showed that the remarkable effect was got on increase the yield,benefit and income when using the technology of covering by the wide film,which provided a basis for the technology extension in the region.
