The results showed that the quality of Phoebe zhennan container seedlings could be estimated from seedling height and ground diameter. The Phoebe zhennan container seedlings were divided into 3 grades： Grade 1 （seedling height ≥ 38 cm; ground diameter ≥ 0.65 cm）, Grade 2 （31.7 cm ≤ seedling height 〈 38 cm; 0.56 cm ≤ ground diameter 〈 0.65 cm） and Grade 3 （seedling height 〈 31.7 cm; ground diameter 〈 0.56 cm）.展开更多

[Method] In the application of container nursery technology of Camellia oleifera grafting in emergent stocks, yellow clay soil, surface soil of pine forest, decomposed edible fungus, peat soil, dung and dirt were mixed by different proportions into five formulae as nursery substrates, with garden soil as the control, in order to investigate the influences of various substrates on the growth of annual Camellia oleifera container seedlings by using randomized block design based on variance analysis and multiple comparisons, and to screen the optimal substrate formula for container nursery of Camellia oleifera. [Result] The influences of different substrates on the transplanting survival rate, seedling height, basal diameter, height-diameter ratio and lateral root length of Camellia oleifera container seedlings were significantly different. Various growth indi- cators of Camellia oleifera container seedlings cultivated in the substrate containing 40% of yellow clay soil ＋ 15% of surface soil of pine forest ＋ 20% of decomposed edible fungus ＋ 20% of peat soil ＋ 5% of dung and dirt exceeded that of the control and other substrate formulae, which could be used as the optimal substrate formula for the container nursery of Camellia oleifera. [Conclusion] This study screened the optimal substrate formula for the container nursery of Camellia oleifera, which provided technical reference for the cultivation of Camellia oleifera container seedlings.展开更多

[Method] Under different seed treatment and seedling style, the seed germination rate and seedling emergence rate of A. nanchuanensis were investigated. [Result] tn both sand bed and direct sowing yellow soil, the seed germination rate, seedling survival rate and seedling emergence rate in the treatment II were all higher than those in the treatments I and III. The average seed germination rate, seedling survival rate and seedling emergence rate in sand beds were 1.5%, 16.27% and 13.95%, respectively higher than those in direct sowing yellow soil. The average seedling emergence rate in sand beds was 2.46% higher than that in containers. Among the 8 kinds of light matrix formulas, the growth of seedlings in the formula VIII was best. In the three treatment groups, the seedling emergence rates, seedling heights and ground diame- ters in the formula VIII were all significantly different from those in the other formu- las. The seedling growth in the formula I and III ranked second, while the seedling emergence rate, seedling height and ground diameter in the formula VII were the poorest. [Conclusion] If conditions allow, the formulas I （meadow soil：vermiculite：yel- low soi1=5：3：2）, III （meadow soil：perlite：yellow soi1=5：3：2） and VIII （peat：forest top soi1=6：4） should be promoted in seedling with light matrixes.展开更多
