【摘要】 以磷石膏作为化学改良剂 ,在河套灌区杭锦后旗沙壕渠试验站进行小面积改良试验。种植作物是美国油葵 G10 1。试验定期测定土壤的水分、盐分、代换性钠及代换总量 ,观测植物生理指标 (株高 ,叶片数 ,杆径等 )。分析磷石膏改良盐碱地对土壤理化性质和葵花生长状况及产量的影响。得出结论 :用磷石膏作为化学改良剂 ,改良盐碱地效果显著 ,具有推广应用的可行性。更多还原

【Abstract】 Using ardealite as chemical improvement agent,It`s conducted improvement experiment in Shahaoqu experimental station of Hangjinhou Banner Hetao irrigation area.In the experiment,It`s planted American Sunflower G101.It`s observed the soil water content and salinty and replaced Na + and the total replaced after improvement and physiological index of plant(such as the height of plant,the numbers of leaves,the diameter of plant.)in regular time.Then,studied the effect on soil physicochemical character and the situation of Sunflower growth and yields in ardealite improving alkali soil.Finally,we drew a conclusion;using ardealite as chemical improvement agent,the improvement effect of it is remarkable.So it can be applicated and disseminated.更多还原
