  • This article through the cultivation experiment, studied the dynamic change of absorption-desorption ratios coastal wind sandy soil on the two kinds of calcium fertilizer under room temperature and 85% field water capacity condition.The results showed that coastal wind sandy soil on two kinds of calcium fertilizer is the negative adsorption on the first 7 day and positive adsorption start at the 20th day and reach the adsorption equilibrium at the 40th day, and then maintain to the 70th day.In the cultivate various stages were fitted by a quadratic equation, linear equation and Langmuir equation.Were available at various stages of training linear equations were fitted and Langmuir equation.Coastal wind sandy soil on two kinds calcium fertilizer absorption ratio is very low, but desorption rate is very high.When adsorption equilibrium the shell power and shell ash calcium adsorption rate only 11.0%-19.2% and 8.8%-15.8%; but desorption rate is 67.0%-76.3% and 72.4%-78.5%.Coastal wind sandy soil showed the highest sorption rate and the lowest rates of desorption when shell power and shell ash calcium applied 9 900、600 mgkg-1.
