摘　　要：为进一步提高盐碱地油用向日葵高产栽培新模式的示范效果,扩大示范区域,采用大区对比方法,集中连片开展"农家肥+有机肥+压明沙+施用磷石膏+地膜覆盖"的综合措施示范,以常规平作、开沟起垄、压明沙、脱硫石膏为对照。结果表明:通过综合模式对盐碱土进行改良,可有效提高向日葵的出苗率和保苗率,进而显著提高向日葵产量。In order to further improve the demonstration effect of high-yield cultivation new model of oil-used sunflower on saline-alkali land and expand the demonstration area, using the regional contrast method, ＂ the farmyard manure ＋ organic fertilizer ＋ pressure sand ＋ application of phosphorus gypsum ＋ plastic mulching ＂ the comprehensive demonstrations measures were concentrated carried out, conventional planting, open ditch ridging, pressure sand, desulfurization gypsum as controls. The results showed that the modified integrated model of saline soil can effectively improve the germination rate of sunflower, thus significantly increase production of sunflower.
