探讨了长期施用有机肥对抑制日光温室土壤盐分积累的作用。试验设3个处理:有机模式,无公害模式,常规模式(CK),结果表明,与常规模式相比,无公害模式和有机模式温室土壤整个剖面的全盐量显著降低,并且在40~60cm层次差异与对照相比达到极显著水平。在离子组成上,增加有机肥投入使SO42-、NO3-、Ca2+、Mg2+含量均有不同程度下降,而HCO3-和Cl-含量高于常规种植温室。
The effects of long-term application of organic fertilizer on the inhibition of soil salt accumulation in solar greenhouse were discussed. The experiment set up three treatments: organic mode, pollution-free mode and normal mode (CK). The results showed that compared with the normal mode, the total salinity of the whole section of greenhouse soil in pollution-free mode and organic mode significantly decreased, The level difference reached a significant level compared with the control. In terms of ion composition, the organic manure inputs increased the contents of SO42-, NO3-, Ca2 + and Mg2 +, while the contents of HCO3- and Cl- were higher than those of conventional greenhouse.
