Abstract：In order to realize the resource utilization of organic wastes in country,the wastes of spring and summer cabbages were chosen as materials.Through 18-day natural and simple retting,the effects of di-atomite (15 g per 1 kg fresh weight)and zeolite(10 g per 1 kg fresh weight,20 g per 1 kg fresh weight)on pH value,ammonium nitrogen,soluble phosphorus and soluble potassium contents in Chinese cabbage retting liquid were studied.The results showed that,compared with control,the pH value of retting liquid had little difference,which were all between 6.56 ~6.70;the ammonium nitrogen content increased by 3.13% ~52.98%;the soluble phosphorus content decreased at different levels with the decline degree of 1 1 .34%~28.45%;the soluble potassium had the biggest decline degree of 23.32%under high zeolite treatment (20 g per 1 kg fresh weight).Through comprehensive evaluation,the effect of diatomite on leafy vegetable waste ret-ting was better than that of zeolite.
