- 摘要:
- 为提高绿萝盆栽科学施肥管理水平,促进绿萝产业发展,本文以青叶绿萝为试验材料,以配方肥氮磷钾比例1.3∶1∶1,氮肥浓度648.80 g?m-3,微量元素浓度9.38 g?m-3为基础处理,按照基础肥料用量的40%、60%、80%、100%、150%、200%和250%的浓度梯度设置T1~T7处理,研究了7个不同浓度的配方肥对温室盆栽绿萝不同生长阶段总根长、根系表面积、茎长、叶面积及SPAD值增量的影响。结果表明:绿萝在生长过程中对肥料浓度的需求呈现出由低到高的趋势,T1、T2在生长前期适合绿萝生长,在生长后期不能满足绿萝生长要求。在不同生长期,T6、T7处理的绿萝均停止生长。最适宜于绿萝生长前期、中期和后期的施肥浓度分别是T2、T4和T5处理。
- Abstract:
- In order to improve scientific fertilization management level of Scindapsus aureus potted in greenhouse,and promote the development of Scindapsus aureus industry,the effects of 7 different concentrations of formula fertilizer on different growth stages of Scindapsus aureus named “green leaf”potted in greenhouse was studied in this paper.On the basis of the ratio of NPK to 1.3∶1∶1,nitrogen fertilizer concentration 648.80 g?m-3,trace element concentration 9.38 g?m-3,we set 7 concentration gradients as 40%,60%,80%,100%,150%,200%,and 250% of base concentration respectively and compared the increment of total root length,root surface area,stem length,leaf area and SPAD in different growth stages.The result showed that,during the growth process of Scindapsus aureus,the demand for fertilizer concentration showed a trend from low to high.T1 and T2 were suitable for Scindapsus aureus in the early stage of growth,but could not meet the requirement in the later stage of growth.At different growth periods,T6 and T7 treated Scindapsus aureus stopped growing.In conclusion,the most suitable formula fertilizer concentration to Scindapsus aureus were T2,T4 and T5 in its early,middle and late period of growth,respectively.
