【摘要】 盐碱地冬小麦采用覆膜栽培技术后 ,土壤含盐量明显降低 ,小麦旗叶 Na+含量降低而K+含量增加 ,小麦单株分蘖数、亩苗数、单株鲜重、干重和单株叶面积都有明显增加 ,小麦单株黄叶数明显减少 ,盐碱地冬小麦的亩产量与对照相比有了显著提高更多还原

【Abstract】 The salt content of soil and the Na + content of flag leaf were dropped while K + content of flag leaf was increased by cultivating technology of winter wheat covering plastic film in saline alkali soil.In the mean while,quantity of tiller per plant,quantity of seedings per mu,leaf area per plant,fresh weight and dry weight per plant were obviously increased,and quantity of yellow leaf was decreased.Per mu yield of winter wheat covered plastic film was obviously higher than control.更多还原
