Abstract:
Taking hybrid orchid GZ2-43 bottle seedlings as the test materials,correlation analysis,principal component analysis,and membership function method were used,the effects of six substrate materials (bark,Pleurotus geesteranus residue,peanut shell,coconut coir,rice husk,and perlite) on the growth and development of hybrid orchid were employed,in order to provide reference for the high-quality development of China′s hybrid orchid industry and the resource utilization of agricultural and forestry waste.The results showed that principal component analysis of the 10 growth indicators yielded two principal components with eigenvalues exceeding 1,collectively explaining 64.51% of the total variance in the dataset.Plants treated with substrate S2 exhibited significantly greater (P<0.05) on plant height,fresh weight,leaf length,number of leaves,and the transverse and longitudinal diameters of pseudobulb compared to control (CK).However,no statistically significant differences were observed in terms of leaf width,SPAD values,root number and root length.The S2,S4,and S3 treatments demonstrated significantly higher comprehensive evaluation coefficients (0.70,0.54,and 0.51,respectively) compared to the control (0.47),indicating superior cultivation performance.In summary,the growth condition of hybrid orchids under S2 treatment (30% perlite+70% peanut shells) is the best,and it is more suitable as a cultivation substrate for bottle seedlings of hybrid orchids.
