Abstract

In order to discuss the changes in the improved soil salinity and soil enzyme activity,a study was conducted to compare the impact of different materials on the saline-alkali soil in Lanxi of Heilongjiang Province.The experiment was arranged in a Randomized Complete Block Design,Mulching、 straw mulch,gypsum and peat.Furfural measures were used to improve the saline-alkali soil that was planted with corn.The results showed that different treatments reduced the levels of soil salinity in different degree and improve soil urease,catalase,invertase activity.The activity of urease,catalase,alkaline phosphatase was improved 7.6%-64.4%,29.5%-79.1%,and 13.0%-49.7%,respectively,compared with that of control.
