【摘要】 以天然沸石为试验材料,通过3a 多的田间小区和示范研究表明,在中、低等肥力的草甸褐土、盐化潮土中施入沸石后,能改善土壤的理化性状,降低土壤盐分浓度,提高肥效,一次施入连续3a 多茬作物都获得了明显的增产效果。更多还原

【Abstract】 The effects of zeolite,used as the test material,on low andmiddle fertility of meadow cinnamon soil and salinized soils in Hebeiprovince were studied.Through over three year’s study of the data frompot cultivation and field plot experiments,the results showed that thezeolite,applied to the poor soils,improved their chemical and physicalproperties,decreasing the salt concentration in the salinized soils withincreasing in fertilizer efficiency,which had endurable effect for threeyears.更多还原
