摘要:
我国有大面积的盐碱滩涂地块,盐碱胁迫是抑制作物产量的一个重要因素,甘薯是我国最重要的粮食作物之一,在盐碱地传统的甘薯栽培方法存在着成苗率低、生长迟缓、产量低、品质差以及成本过高等问题。针对这些问题,本栽培技术在盐碱地采用耐盐碱甘薯新品种济徐23,灌水压碱、深耕断碱、增施有机肥和氮肥、地膜覆盖、适时晚栽、施用腐植酸钾肥料、生根粉浸苗、前期化学调控促秧等一系列技术手段,解决0.3%~0.5%的盐碱地甘薯栽培保苗难、发育迟缓、产品质量差、产量低的问题,实现中度盐碱地甘薯的高产、优质、高效的统一。

Abstract: There are large areas of coastal saline wet lands in China and the saline-alkali stress is one of the most important factors limiting the crop yield, while the sweet potato is one of the most important crops in China. In the traditional cultivation system of sweetpotato in mudflat saline land, some problems occur such as low surviving rate, developmental retardation, low yield, poor product quality and high cost. In view of the problems above, this paper provided cultivation techniques, which based on the high salinity tolerance sweetpotato cultivars Jixu23, matched a series of culti-vation measures, such as irrigation, deep plowing, increasing organic and nitrogen fertilizer, plastic mulch, appropriate later planting, using potassium humate fertilizers, ABT-dipping seedlings, chemical regulation seedling promoting and so on, through which sweetpotato can be grown smoothly in the saline-alkali land of 0.3% to 0.5%, realizing the unity of high yield, high quality and high benefit in sweetpotato production in moderate saline-alkali land.
