农作物在复垦农田中改盐效果研究

ffect of Crops on the Soil Salinity Improvement in Reclaimed Farmland

以干旱区绿洲复垦初期的盐渍化农田作为研究对象,采用农田多种作物混合种植模式进行适盐改良研究。结果表明,油葵、小麦、打瓜作为盐渍化弃耕地复垦的先锋作物较好;而从一个灌水周期来看,油葵、打瓜表现出改良土壤盐渍状况以及对盐分的适应性较好;在种植模式方面,间套作对于适盐及改良土壤盐渍化状况要优于单作模式。

The effect of crop planting on the reclamation of abandoned salinization cropland was studied in oasis of arid zone.The results showed that oil sunflower,wheat and seeding-watermelon were better pioneer crops in reclamation of abandoned salinization cropland.Meanwhile,oil sunflower and seeding-watermelon were outstanding in improving saline soil and adapting to soil salinity in one irragation circle.In terms of cropping patterns,intercropping was superior to single crop in improving saline soil.
