摘 要：
针对黄河三角洲地区光热资源利用率低,种植结构单一,中轻度盐碱地土壤有机质含量低等问题,提出了基于秸秆还田的中轻度盐碱地冬小麦-夏谷子轮作高产栽培模式。通过小麦、谷子秸秆全量还田的方式提高盐碱地有机质含量;通过耐盐碱小麦品种和沟播的栽培方式,改善了盐碱地小麦群体不足和后期早衰的问题;适宜早熟杂交谷子品种宽泛的适播期,可以抢墒播种或雨后播种,减少了谷子播前造墒对灌溉淡水的依赖。综合技术对充分利用黄河三角洲的光热资源,改良盐碱地和丰富当地种植结构具有一定的指导意义,并具有良好的发展前景。

摘 要：
In view of the low utilization of solar and heat resource,monotonous planting structure and low content of organic matter in saline-alkali soil of the Yellow River delta region. The high yield wheat-millet rotation cultivation model based on straw returning on saline-alkali land is proposed. The soil organic matter content of saline-alkali soil was enhanced by wheat and millet straw returning,the problems of less populations and sharp senescence in late stage of wheat were resolved by furrow planting. And early-maturing millet variety was less depending on irrigation by flexible sowing time. The technology has some guiding significance for making full use of the abundant solar and heat resources in the Yellow River delta,ameliorating the saline-alkali land and enriching the local planting structure,and has good prospects for generalize.
