Chinese J ou rnal of Ecology , 1999 ,18 ( 1) :25 - 29 . Sulfurremoval gyp sum was applied as an amendment of heavy soda salinealkali soil and showed ob vious salinealkali removal effect . The sulfurremoval gyprum can decrease soil p H and alkalinity . 1 Amount of t he amendment applied is from 5787 to 23 149 kg ·ha . As t he amount of t he amendment used increased , t he soil p H and alkalinity could correspondently decreased . It made maize grow in barren land and increased t he yield . Key words : sulfurremoral gyp sum , soda salinealkali soil ,effect . 　　石膏改良盐碱土在我国已是成功的经 年间所获试验结果概述如下 。 验 ,但是 , 由于受到资源条件的限制及其价 1 　试验条件 、
