Abstract:

In order to screen out the proper krilium and their proportioning for effectively ameliorating alkaline soil, environmental protection and low cost 6 kinds of krilium were added to test soil for evaluating their effect on amelioration of saline and alkaline by pot experiment, soil total salt content, soil pH value and wheat yield were measured. These dates may provide methodological basis for ameliorating alkaline soil in this region. The results showed that saline water irrigation compared with freshwater irrigation significantly decreased on wheat yield and kernel weight by respective 45.2%, 12.1%, no significantly differences in wheat biomass, root weight, root length and plant height when krilium were not application; The combine application patterns of difference krilium significantly increased by 190.0%, with the highest wheat yield for the combined application patterns of S7 (11.57 spike per pot), at the same time, significant increasing on other index, too. The highest in soil total salt content and soil electric conductivity at depths of >20 cm after wheat harvest, the lowest at depths of 5-20 cm. The saline water irrigation compared with freshwater irrigation significantly increased on soil total salt content and decreased on soil pH value. The highest soil total salt content for the combined application patterns of S4. Wheat biomass, kernel weight showed an extremely positive relationship with wheat yield. There was a negative correlation between the soil pH value and wheat yield.
