Screening on substrate of container seedlings for rare species Ormosia henryi
To screen the optimal substrate of container seedlings for rare species Ormosia henryi,we conducted the container seedling test by designing seven different substrate formula with peat,vermiculite and perlite,yellow soil as control.The results indicated that the Ormosia henryi container seedlings exhibited obviously various growing situation in different substrate.The seedlings quality in light medium formula combination with peat,vermiculite and perlite was better than that in the yellow soil,the seedling quality in the mixture substrate was superior to that in the substrate single.The height,ground diameter,total biomass,seedling quality index and chlorophyll content of seedlings growing in the No.6 substrate with peat,vermiculite and perlite according to the volume proportions 2∶1 ∶ 1 were maximum.The No.7 (Vpeat ∶ Vperlite =2∶1),No.5 (Vpeat∶ Vvermiculite ∶ Vperlite =3∶ 1 ∶ 1) substrates followed.Considered the growth and seedling costs,the No.6 substrate with peat,vermiculite and perlite according to the volume proportions 2∶ 1∶1 was the optimum one,it would be popularized and applicated in production.
