Abstract:
Taking Tagetes erecta as test materials，using decomposed cow dung as peat substitute,the proportion of decomposed cow dung in the mixtures elaborated with peat were 0%，20%，40%，60%，80%，100% v/v and substrate of 100% peat as CK,the effects of different ratios on the physical，chemical properties and the growth of Tagetes erecta were studied,in ordre to resolve the problem of shortage of the peat resources.The results showed that the addition of decomposed cow dung to the growing media produced an increase in the bulk density，and a decrease in the total porosity.The aeration porosity had the same trend with bulk density，which was contrary with the holding porosity and WHP/AP.The addition of decomposed cattle dung had the great differences to the peat in the pH and EC.Adding the decomposed cow dung in the peat could increase the height，stem diameter，leaf color value，the number of flowers and colored diameter of the Tagetes erecta significantly，except in the pure cattle manure compost，which the Tagetes erecta was dead.
