宁夏马铃薯抗旱节水技术集成与推广

Integration and Popularization of Drought Resistance and Water-saving Technology of Potato in Ningxia

本文结合宁夏中南部山区水资源特点,在有水源地区和补充灌溉条件地区,重点集成推广马铃薯滴灌、喷灌、水肥一体化高产栽培技术模式,结果表明:在旱作区推广以覆膜保墒为主的马铃薯旱作节水农业技术,可有效提高降水利用率和水分生产效率,降低肥料施用量,保护环境,达到节肥节水、抑制杂草、降低成本的目的,对提高马铃薯产量,促进农业增效、农民增收和贫困地区脱贫致富等发挥重要作用,在西北旱作农业区具有较好的借鉴和推广价值。简要介绍了宁夏马铃薯抗旱节水主要技术模式及关键技术措施。

Combined with characteristics of central and southern mountainous areas of Ningxia, integration technology of drip irrigation, sprinkler irrigation and fertigation for potato is primarily popularized in the areas with water resource and supplied by irrigation. The results showed that film-mulching cultivation technology for dry-land potato popularized in dry farming area could effectively improve precipitation productive efficiency, decrease fertilizer application and protect environment,realizing fertilizer and water saving, inhabitation of weeds and cost reduction for improving agriculture benefit, increasing peasant income and shaking off poverty. Meanwhile, key cultivation techniques of water-saving and drought-resistance for potato in Ningxia were introduced.
