| 摘 要： | 文章以黄心土为基础,选用泥炭土、椰糠、蘑菇渣3种常用轻基质材料,设置不同比例组成15种基质配方,通过研究不同基质配比处理下洋紫荆Bauhinia variegata的苗高、地径、地上部分干重、地下部分干重、生物量、根冠比、根系生长,评价其育苗效果,确定培养基最优配比。结果表明:不同配方基质对容器苗的生长有显著影响,处理组Z7(黄心土:泥炭土:椰糠=2:1:1)、处理组Z14(黄心土:椰糠=1:4)、处理组Z5(黄心土:椰糠=4:1)的洋紫荆容器苗综合评价值为0.75,0.63和0.55,Z3(椰糠=1)、Z13(黄心土:泥炭土=1:4)、Z6(黄心土:蘑菇渣=4:1)的洋紫荆容器苗综合评价值为0.32,0.39和0.43。综上所述,黄心土:泥炭土:椰糠=2:1:1的基质配比是洋紫荆容器苗最为理想的轻型基质配方。

| Abstract: | The suitable light mediums precision breeding technology for Bauhinia variegata was studied in this paper.The light mediums for B.variegata container seedlings was made of yellow soil,peat soil,coconut bran and mushroom residue.The seedling height,ground diameter,dry weight of aboveground part,dry weight of underground part,biomass,root shoot ratio and root growth of B.variegata were studied by adjusting the ratio of the four ingredients to evaluate its seedling effect and determine the optimal medium ratio.The results showed that there was a significant difference between growth of container seedlings cultivated in different mediums.For the treatment group Z7(yellow soil:peat soil:coconut bran=2:1:1),the treatment group Z14(yellow soil:coconut bran=1:4)and the treatment group Z5(yellow soil:coconut bran=4:1),the comprehensive evaluation values of the B.variegata container seedlings were 0.75,0.63 and 0.55,respectively.For treatment group Z3(coconut dust=1),Z13(yellow soil:peat soil=1:4)and Z6(yellow soil:mushroom dregs=4:1),the comprehensive evaluation values of B.variegata container seedlings were 0.32,0.39 and 0.43.In summary,the medium ratio of yellow soil:peat soil:coconut bran=2:1:1 is the most ideal light medium formula for B.variegata container seedlings in this study. |
