Department of Biology and Chemistry Engineering Fuqing Branch of Fujian Normal University Fuqing China2. College of Resources and Environment Fujian Agriculture and Forestry University Fuzhou China AbstractA soil culture experiment was conductedtaking calcium fertilizer at variable values the changes of the available calcium in soil were studied through application of different kinds of calcium fertilizers in yellow mud field by room temperature cultivation. The results indicated that application of different kinds of calcium fertilizers in yellow mud field influenced the available calcium of soil the speed at which fertilizers released available calcium was in the orderlime nitrate > calcium hydroxide = calcium phosphate primary > calcium magnesium phosphate > dolomite dust. In the pot experimenttaking calcium at variable valueseight treatments which had four repeats were designed to study the effects of soil available calcium on NP and K content and uptake of flue-cured tobacco in a completely randomized design. The results indicated that with the increase of application of calcium fertilizers the N contentp content and their uptakes of tobacco-leaf decreased graduallythe N content and uptake of Ca8 treatment dropped by % and % respectively in JB07093 FUYC E - mailwtz_ @ 163. com* E - mailxiongdz@ 126. com
2 contrast with Ca1 treatmentthe P content and uptake of Ca7 treatment dropped by % and % respectively in contrast with Ca1 treatment. The K content and its uptake of tobacco - leaf increased first and decreased later the K content of tobacco-leaf with Ca3 treatment reached the peak value the K uptake of tobacco-leaf with Ca6 treatment reached the peak value which increased by % and % in contrast with Ca1 treatment. The NP and K contents and their uptakes of tobacco-root and tobacco-stem had the similar regular pattern to the K content of tobacco-leaf. The whole tobacco plant N uptake decreased gradually that of minimum Ca8 treatment dropped by % in contrast with Ca1 treatment. The whole tobacco plant P and K uptakes increased first and decreased later those of Ca3 treatment increased by 6. 17% and % in contrast with Ca1 treatment.
