摘　　要：施用复合微肥能明显提高耐盐小麦德抗 961的出苗率和冬前分蘖数 ,使其单株鲜重、株高、亩穗数、穗粒数和旗叶面积、鲜重、含水量、K+含量及净光合速率显著增加 ,同时 ,使德抗961的产量构成因素明显大于只施基肥的对照 ,使前者的亩产量达 357.73kg,而后者只有2 96.45kg。因此 ,选择耐盐品种 ,播种时补施复合微肥是盐碱地小麦丰产的重要技术之一。Microelement complex fertilizer increased not only the emergence rate and the tiller number of wheat DK 961 obviously before winter but also the fresh weight per plant,height per plant,panicle per mu,grains per panicle and area,fresh weight,water content,potassium content and net photosynthetic rate of flag leaves markedly,so it increased the grain yield of salt tolerant wheat DK 961 significantly.The yield related factors of wheat DK 961 using microelement complex fertilizer are much higher than those of the control,the yield of the former being about 357.73kg per mu,but that of the latter only 294.45kg.In conclusion,selecting salt tolerant varieties and using microelement complex fertilizer is one of the important strategies in raising wheat grain yield on saline soils.
