盆栽用土量对万寿菊生长及农艺性状的影响

为了研究盆栽用土量对万寿菊生长的影响，给盆栽万寿菊栽培提供参考。在陇南师范高等专科学校梁山校区荒地，以大田栽植为对照，采用盆栽的方法(盆栽土不添加任何营养物质)，研究了盆栽用土量(3、5、7 kg)对万寿菊农艺性状的影响。结果表明，大田种植万寿菊的部分生理指标显著高于盆栽万寿菊，5、7 kg的盆栽用土量之间指标差异并不显著，3 kg的盆栽用土量部分生理指标显著低于5、7 kg。综合各农艺性状的观测结果，推荐万寿菊盆栽用土量为5 kg。

Effects of Soil Weight in Pot Culture on Growth and Agronomic Characters of Marigold

In the wasteland of the Liangshan campus of Longnan Teacher College, taking the cultivated marigold as the control(CK) and adopting the method of pot planting with the amount of soil used for potting as 3 kg, 5 kg and 7 kg, respectively, the effects of soil weight in pot on the agronomic characters of marigold were observed with no additional nutrients added in the whole growth process. The results showed that some physiological indexes of CK treatment were significantly higher than those of pot marigold. However, the index difference between 5 and 7 kg of potting soil were not significant. Some physiological indexes using 3 kg of potting soil were significantly lower than those of 5 and 7 kg of soil weight. Based on the results of various agronomic characters, this study recommends a pot soil weight of 5 kg.
