Abstract:
With coastal saline soil as test object,the different proportion of corn stalks and decomposed cow dung were added to test soil for evaluating their effect on amelioration of saline and alkaline by the field experiment,soil total salt content,soil pH value and Hibiscu grandiflorus L.growth conditions were measured.The results showed that the corn stalks were better than decomposed cow dung in improving soil desalting effect.The best treatment was 2(corn stalks 0.10 m3/m2),followed by treatment 5(decomposed cow dung 0.05 m3/m2+corn stalks 0.05 m3/m2).The decomposed cow dung was obviously for improving saline-alkali soil fertility,plant survival rate and plant growth.The best treatment was 3(decomposed cow dung 0.10 m3/m2),followed by treatment 5 for plant growth.Considering the effect of corn stalks and decomposed cow dung on soil desalting,plant growth and survival rate,and concluded that treatment 5 could improve the desalting effect and soil fertility,and basically achieved the purposes of comprehensive soil amelioration.But corn stalks and decomposed cow dung didn’t reduce the soil pH value.Therefore suggested that increasing phosphorus gypsum,humic acid and other acidic soil additives to improve soil pH value.
