| 摘 要： | 采用盆栽试验方法．探讨不同施肥水平对剑麻根系和植株生长的影响。试验设4个处理，分别为BO（对照），B1（低肥）、B2（中肥）、133（高肥）。试验研究结果表明：3种不同施肥处理对剑麻根系和地上部生长有一定影响；在低肥处理下．剑麻的根条数、根鲜重、根干重、剑麻株高、叶片数、单叶片长、单叶鲜重、株鲜重、株干重，在所有处理中最大；而随着施肥浓度的提高，剑麻的根条数，根鲜重、根干重、剑麻株高、叶片数、单叶片长、单叶鲜重、株鲜重、株干重与B1相比，都有明显下降。可见，低肥处理时最能促进剑麻的生长发育。

| Abstract: | To explore the effects of fertilization on root and aboveground growth of Yucca gloriosa, individuals of Y. gloriosa was planted in pots under four level fertility treatments （i.e. Control B0; Low level B1; Middle leve; High level）. The results showed that fertilization could affect the root and aboveground growth to some extent. The branches of roots, root fresh biomass, root dry weight, height, number of leaves, length of leaf, fresh biomass per leaf, total fresh biomass and dry weight were the largest under B1 treatment. Thereafter, they all decreased obviously with increasing fertilization level. In summary, the low level fertilization was the optimal treatment which could promote growth of Y. gloriosa. |
