Abstract:

In order to explore the technique of artificial cultivating and to select the best substrates for seedling culture of Parashorea chinensis, container-growing seedling cultivation used 4 substrates with different ratio of yellow soil, turf ash, coir pith, coarse sand and pearlite as testing materials and the effects of the cultivation medium on the seedling growth and quality of Parashorea chinensis were studied. The results indicated that the average seedling height, the basal diameter, the number of leaf, the leaf area per plant, the growth of root systems and the biomass per plant was significantly different among the different treatments of substrates. M3(50% yellow soil+30% turf ash +20% coir pith+ 3% Phosphate fertilizer) was the best suitable nursery substrate for seedling growing of Parashorea chinensis. The average seedling height, the basal diameter, the leaf area per plant and the biomass per plant of the seedlings under the M3 nursery substrate treatment increased by 19.41%, 14.69%, 45.56% and 48.26% respectively in comparison with the seedlings under the worst treatment. So the M3 nursery substrate was the ideal collocation for Parashorea chinensis and recommended for practical production.
