| 摘要: |
| 在温室条件下，用盆栽试验方法研究了基施鸡粪和追施化肥对分枝期以前木立芦荟生长的影响。结果表明，单施化肥与无肥对照间木立芦荟的生长量差异不显著；低肥处理木立芦荟生长量最大，单株根条数增加，株高、分枝数、净增叶片数均高于对照；基施鸡粪并追施化肥后，芦荟鲜重比相应单施鸡粪处理显著下降，株高降低；高量鸡粪并追施化肥的处理，芦荟生长受到严重抑制，植株鲜重比对照下降13.8％，叶片水分含量较对照显著降低，平均根长较对照减小。各处理芦荟叶片中N、K含量变化不大，除单施化肥、高量鸡粪加化肥处理外，其他施肥处理芦荟叶片中全磷含量大幅度提高，为无肥处理的1.8～2.3倍。 |

| Effect of different fertilization level on the growth of Cande Labra Aloe |
|
|
| Abstract: |
| In greenhouse,pot experiment was conducted to study the effects of basal dressing of chicken manure and dressing chemical fertilizers on growth of Cande Labra Aloe before its branching period.The results showed that for the growth amounts of Cande Labra Aloe,there was no significant difference between the dressing of non fertilization and the solely dressing of chemical fertilizers.Under low fertilization condition,the growth amount of Cande Labra Aloe was the largest,root number,height,branching number and the number of net increased leaves per plant were all higher than that of control treatments,respectively.Comparing the treatment of basal dressing of chicken manure as well as post dressing of chemical fertilizers with the treatment of solely dressing of chicken manure,the fresh weight of the former decreased significantly,and the height also dropped.Under basal dressing of high amount of chicken manure as well as post dressing of chemical fertilizers,the growth of Cande Labra Aloe was seriously inhibited,comparing with control group,the fresh weight of Cande Labra Aloe decreased by 13.8%,the water content in leaves reduced significantly,the average root length lowered,too.Under different treatments,there was no obvious change to the nitrogen and potassium contents in leaves of Cande Labra Aloe,except for the treatment of solely dressing of chemical fertilizers and the treatment of basal dressing of high amount of chicken manure as well as dressing of chemical fertilizers,under other fertilization treatments,the phosphorus contents in the leaves of Cande Labra Aloe increased to a large extent,they were 2-3 times that of no fertilization treatment. |
