The pot experiment results of zeolite blended mixed
fertilizer(ZBF) on vegetables and field crops were compared. Meanwhile,
the soil nutrients situation in different growth stages of rapeseed and the quantity of nutrients absorbed by rapeseed in seedling stages were investigated, the slow release effects of N, P, K by ZBF were discussed. Besides, the proper proportion of the carrier addition and the soil amending effect were also studied. The results indicated that the yield
increment effect of vegetables were better than field crops;in seedling stage of rapeseed by application of ZBF, the soil available nutrient of N?P?K all decreased to some extent, and so were the nutrient absorption by plants;as for the proper proportion of the carrier addition, it's not the higher the better, for rapeseed, 10～15% was better;the soil pH could increase as high as 0.5, and the soil exchangeable Mn could decrease about 90% by application of ZBF compared to the check blended mixed
fertilizer, therefore,ZBF could release the Al?Mn toxicity caused by soil acidity after application of chemical fertilizer, this was a internal factor of yield increment by application of ZBF.
