The effect of different applying manure and straw on soil secondary salinization and rape biomass in greenhouse soil was studied by pot culture. Both manure and straw have installed five treatments and a control group. The results showed that the soil soluble salt in the soil treated by manure and straw were lower than the control group's. The soil salt in the manure treatment groups could first decreased and then increased when the manure was applied furthermore. In the straw treatment groups, soil salt reduced with increase of amount of straw. The rape biomass in the groups of both manure and straw treatment were significantly larger than control group's, and the manure was better than straw. While applying manure and straw could meliorate secondary salinity and enhanced soil quality, it was an effective way to achieve sustainable development of agriculture. |
