石膏不同施用方法改良碱化土壤效果浅析
EFFECT OF DIFFERENT APPLYING METHODS ON IMPROVING ALKALINE SOILS WITH GYPSUM
【摘要】 试验研究了不同施用石膏方法对改良碱化土壤的效果差异,结果表明:把定量石膏与60cm土层的土壤全部混均改良效果最好,但受现实条件的制约,成本高,不可取;把石膏与20cm土层混均的改良效果远大于把石膏施与土壤表层的改良效果,且个别碱化指标优于其它两种处理,生产上也易实现。
【Abstract】 The effect of different methods of applying gypsum on improving alkaline soils were studied. The resulted indicats:in three methods,mixing gypsum with 60cm depth soil is the best methods;mixing gypsum with 20cm depth soil is worse than above method and applying simply gypsum on the surface of soil is the worst. However,the second method is more practicall than others.
