- 摘要:
- 以万寿菊为试材，以腐熟牛粪为泥炭替代物，以纯泥炭为对照，研究了添加牛粪20%、40%、60%、80%、100%（v/v）不同配比条件下混合基质理化性状的差异以及对万寿菊植株生长的影响,以期为解决泥炭资源短缺及成本高的问题提供参考。结果表明：混合基质的物理性状中容重随着牛粪量的增加而增加，总孔隙度随着牛粪量的增加而降低，通气孔隙也是随着牛粪量的增加而增大，持水孔隙和水气比逐渐降低；化学性状中pH值、EC值不同处理之间差异显著，二者均随着牛粪量的增加而升高；100%牛粪处理下万寿菊死亡，其它处理条件下，添加牛粪之后显著提高了万寿菊株高、茎粗、叶色值，促进万寿菊花的产量，其中添加牛粪60%处理效果最好。
- 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.
