China is one of the largest countries with huge amount of alkaline-alkali soil, how to ameliorate these lands is a hotspot.17 kinds of Krilium were added to test soil for evaluating their effect on amelioration of heavy soda saline-alkali soil. We measured soil pH, soil electrical conductance and germination parameters of cabbage seeds as screening means to screen out the proper krilium and their proportioning for effectively ameliorating alkaline soil. These data may provide methodological basis for ameliorating alkaline soil in this region. Our result showed that: 1) Among 17 kinds of krilium, 11(HPMA、Gypsium、HEDP、T225、PAPEMP、MA-AA、ATMP、AA/AMPS、PAA、Charcoal、BHMTPMPA)of them were effective agents and could effectively induce seed germination with respecting to the no any germination phenomena at the control saline-alkali soil. These effective agents played a remarkable role to reduce the pH, but slightly change the electrical conductance of soil solution. HPMA was the best one in ameliorating saline-alkali soil, which has been manifested by the various index of seed germination. For example, the germination ratio, germination index, germination vigour index were respectively 72.5%, 36.2, 1.2. Soil pH value significantly correlated with the seed germination ratio, germination potential and germination index(p<0.05), but soil electrical conductance did not correlated with any one of the seed germination parameters(p>0.05), showing the important function of pH in explaining the effectiveess of different krilium. 2) Addition of gypsum together with other organic agents could strongly increase the ameliorating effectiveness, which has manifested by the data of 9 agent of HPMA, PAA, charcoal, wood vinegar, EDTA, H+ resin, citrate acid, citrate calcium and NTA. The seed germination ratio, gernination index, and germination vigour index has largely increased, showing the plus effect of gypsum. 3) gradient experiment of mixing addition of HPMA and gypsum showed that the protocol of HPMA(42.8L/m3) and gypsum(25kg/m3) was the most effective one for the amelioration practice. These various indexes were relative close to the corresponding indexes at control normal loam, mixed application is not suitable. We should consider that multiple addition or increase concentration of Krilium in field practice may strength the effectiveness of soil amelioration.
