Abstract:

To screen organic culture substrates for garden flowers, cassava residue, wormcast, pine bark, coconut coir were used as raw materials to make 5 substrates by volume ratio. Cultivation experiment was carried out to study the effects of the substrates with different mixing proportions on the growth of Jasminum sambac. The principal component analysis was used to analyze the effects of different substrates. The results indicated that compared with garden soil: peat: perlite=6:2:2 (CK), wormcast: peat: perlite=6:2:2 (T2) and cassava residue: peat: perlite=6:2:2 (T3) had an evident advantage in promoting stem diameter, branch number, chlorophyll content, bud number and biomass of J. sambac, and the plants grew well. T2 and T3 could improve the soluble sugar content to enhance cold tolerance of J. sambac, and T3 increased the root activity of J. sambac significantly. Through principal component analysis of 12 growth indexes, the total score of T3 was the highest, and T3 could be recommended as a substrate formula for J. sambac.

Key words: Jasminum sambac, organic waste, culture substrate, growth index, principal component analysis
