   Xiaoyang Cui- Effects of fertilization on needle nutrition & cone yield.pdf (2.4M), Down : 1, 2018-09-08 16:52:12
Effects of fertilization on needle nutrition and cone yield of a dual-purpose Pinus koraiensis plantation established for timber and pine nut production. Xiaoyang Cui.

1. On relatively infertile soils, the needle N and P level of Korean pine plantations are sensitive or responsive to fertilization.
2. No potassium deficiency would exist in the pine trees.
3. NP and NPK combined application may increase the setting percentage of the pine trees, while  N single application decreases it.
4. The optimal fertilization scheme should be the combination of NP.
5. Fertilization should be an essential technical measure for the dual-purpose plantations established for timber and pine nut production, on account of its intense consumption of soil fertility.
