- 摘要:
- 以云南金钗石斛实生苗为试材，在人工栽培条件下，分别施用浓度均为5% 的菜籽麸、花生麸、桐麸发酵液和复合肥，分别测定其分蘖数、粗度、株高、叶片数、冠幅、 鲜重、干重、干鲜比等生物学性状、SPAD值和石斛碱含量。结果表明：施用花生麸，有利于增加金钗石斛的株高、分蘖数、叶数；施用菜籽麸，可以增加金钗石斛干物质重量；施用桐麸有利于增加金钗石斛的粗度、鲜重和石斛碱含量；菜籽麸和复合肥混合施用，可以提高叶绿素含量，增加干鲜比。试验结果表明，不同肥料在金钗石斛的不同生长发育阶段具有不同的特性，因此有选择性地施用这些肥料，可以达到增加和提高金钗石斛的产量和石斛碱含量的目的。
- Abstract:
- The zymotic fluid of 5% the rapeseed cake,peanut bran and tung cake,and 5% aqueous solution of the compound fertilizer were respectively applied to the Yunnan Dendrobium nobile Lindl.seedlings under the conditions of the artificial cultivation.The biological character,tiller number,plant heights,stem diameter,crown width,fresh weight,dry weight and rate of dry weight to fresh weight of stems and leaves,and SPAD value,dendrobium alkali contents were measured respectively.The results showed that zymotic fluid of the peanut bran was conducive to the increase of plant height,tiller number,leaf number of Dendrobium nobile Lindl.,the zymotic fluid of rapeseed cake can increase dry matter weight of Dendrobium nobile,the zymotic fluid of tung cake was conductive to the increase of diameter,fresh weight and the content of dendrobium alkali,the mixd compound fertilizer and zymotic fluid of rapeseed cake can increase the content of chlorophyll and the rate of weight to fresh weight of stems and leaves.Therefore,could selectively fertilize in different stages of growth and development of Dendrobium nobile Lindl.according to the characteristics of these fertilizers,in order to increase the yield and dendrobium alkali contents of Dendrobium nobile Lindl..
