Responses of growth and afforestation performance of Pinus tabuliformis container and bareroot seedlings to fall fertilization
【Objective】 The aims of this research were to examine the responses of container and bareroot Pinus tabuliformis seedlings to nursery fall fertilization supplements and assess their subsequent two-year field performance. This study was conducted to provide a theoretical basis and technical support for the cultivation of high-quality P. tabuliformis seedlings. 【Method】 Fall fertilization was applied when the terminal bud ratio reached 90% of the total seedlings. P. tabuliformis container seedlings and bareroot seedlings were supplied with fertigation (i.e., irrigation with soluble fertilizer) at 0 (control), 12, 24, and 36 mg/plant. The effects of fall fertilization on growth and afforestation performance were then tracked and analyzed over two-year using the following cirteria seedling height, root-collar diameter(RCD) and nutrient content, etc. 【Result】 The height, RCD, biomass, N content, P content and K content of container seedlings with 24 mg/plant were higher than those of the other doses. In addition, the total biomass, N content, P content and K content were significantly increased by 41.8%, 31.4%, 65.6% and 48.8%, respectively, compared to those of the control seedlings, whereas the bareroot seedlings were less affected by fall fertilization. The distribution of N content in the organs of container seedlings was root > needle > stem, whereas that in the bareroot seedlings was needle>root>stem. The distribution of P and K contents in the organs of container and bareroot seedlings exhibited the same order: needle>root>stem. The results of the rainy season afforestation test showed that the rate of afforestration was significantly affected by the seedling type. Compared with the bareroot seedlings, the relative growth in the height and RCD of container seedlings were significantly higher in the first year of outplanting and the following spring, and the survival rate of container seedlings in the following spring was similar to the pattern observed for the relative RCD. The relative growth in height in the second year spring was significantly affected by fall fertilization, and fall fertilization at 24 mg/plant yielded the highest value. The afforestation survival rate, relative growth of height, and RCD of seedlings were closely related to seedling root biomass, root shoot ratio, root N content, root P content, root K content and stem P content in the initial stage of afforestation. 【Conclusion】 Fall fertilization at 24 mg/plant was best for optimizing the morphological growth and nutrient accumulation of P. tabuliformis container seedlings. The survival rate and growth of 1-year-old P. tabuliformis container seedlings were significantly greater than those of the bareroot seedlings.
