Abstract
The effects of phosphogypsum and zeolite on active aluminium form in acidic yellow soil and nutrient balance of carrot were studied by using the indoor incubation culture,pot cultivation test and indoor analysis method.The results showed that the exchangeable Al(Ex-Al) and hydroxyl Al(Hy-Al) in acidic yellow soil were 35.5 %-41.0 % and 24.5 % lower than CK with increase of applying phosphogypsum and zeolite amount respectively,Ex-Al dropped rapidly in the first month and then slowed down during 2-4 months and Hy-Al decreased slowly with time increase of phosphogypsum and zeolite application,and the drop range of Ex-Al and Hy-Al at 11-18 ℃ was slower than that at 18-25 ℃.The dry weight of carrot with applying phosphogypsum was 3.4-5.9 times that of CK.The P,K,S and Ca absorption amount of carrot with applying phosphogypsum was 127.0 %,31.2 %,70.1 % and 75.1 % higher than that of CK respectively and Al absorption amount of carrot with applying phosphogypsum was 50.4 % lower than that of CK.The N/S ratio,K/S ratio,K/Ca ratio,S/Al ratio and CA/Al ratio of carrot plants had the significant effect on dry weight of carrot plants.
