摘  要:
通过土壤培养试验,初步研究了不同配比的糠醛渣复合改良剂对吉林省西部重度盐碱土的改良效果,从中找出改良效果较好的改良剂配方。结果表明,糠醛渣改良剂施入重度盐碱土后,土壤的理化性状发生了显著改善,主要表现为:土壤中大粒径(0.25~1 mm)的微团聚体数量明显增加,土壤容重变小,土壤平衡溶液的pH明显下降,CE(电导率)、Na+浓度以及ESP(碱化度)下降,但土壤交换性阳离子总量变化不大。通过试验结果可以看出,在1 500 g盐碱土中加入糠醛渣、石膏和硅酸铝的剂量为60 g、25 g和5 g时,对盐碱土理化性质的改良效果较好。

摘  要:
Through soil incubation experiment we studied effect of different ratio of the compound modifier formula of furfural residue on severe saline-alkali soil in western region of Jilin province in order to find out the optimal formula.The results showed that severe saline-alkali soil properties improved remarkably after adding furfural residue,and the soil displayed as follows:microaggregate in diameter 0.25-1mm increased apparently,the bulk specific gravity reduced,the pH of soil solution decreased,CE,Na+ concentration and ESP deceased,whereas CEC was not obviously changed.In conclusion the 8th was suitable for alkali soil improvement.
