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.
