Embodiment 1

[0070] Example 1 Effects of Different Nitrogen, Phosphorus and Potassium Proportions on the Growth of Minnan Seedlings

[0071] Table 2 reflects the effects of different ratios of nitrogen, phosphorus and potassium on the growth of Phoebe spp. seedlings. The seedling height here is the height measured after the last fertilization. It can be seen from the results that the growth of seedling height in each fertilizer ratio group T2-T14 was higher than that in the control group T1, and there was a very significant difference. Among them, when the mass ratio of nitrogen, phosphorus and potassium was 2.66:13.32:1.78, the T13 group increased the most, with a total increase of 43.4cm, which was 134.59% of the control group. Next, the growth of seedling height was T2 (37.8 cm), and the mass ratio of nitrogen, phosphorus and potassium was 0:13.32:3.56; followed by T7 (36.0 cm), the mass ratio of nitrogen, phosphorus and potassium was 5.32:19.98:3.56.

Embodiment 2

[0075] The influence of embodiment 2 different nitrogen, phosphorus and potassium ratios on seedling diameter growth

[0076] Table 3 reflects the effects of different ratios of nitrogen, phosphorus and potassium on the growth of Nannan seedlings' ground diameter. The ground diameter here is the same as the seedling height, which is the value measured after the last fertilization. It can be seen from Table 3 that during the whole fertilization process, the ground diameter of Nannan seedlings increased with different fertilizer ratios. The growth of seedling height of each fertilizer ratio of T2-T14 was higher than that of control T1, and there was a very significant difference. Among them, the T13 group had the largest increase in the mass ratio of nitrogen, phosphorus and potassium at 2.66:13.32:1.78, with a total increase of 5.34 mm, which was 98.51% of the control group. Followed by T2 group, the mass ratio of nitrogen, phosphorus and potassium is 0:13.32:3.56, the total g...

[0080] The impact of embodiment 3 different nitrogen, phosphorus and potassium ratios on seedling biomass

[0081] Table 4 reflects the effect of different ratios of nitrogen, phosphorus and potassium on the biomass of Phoebe spp. seedlings. The biomass of seedlings here is the value measured after the last fertilization. The fresh weight of the aboveground part, the fresh weight of the underground part, the dry weight of the aboveground part, and the dry weight of the underground part of the seedlings in December are shown in Table 4. Different fertilizer ratios have a significant impact on the biomass of the Nannan seedlings, and the growth of the total fresh weight is the best The top three named: the mass ratio of nitrogen, phosphorus and potassium was 5.32:13.32:3.56 (T6), 5.32:0:3.56 (T4), 5.32:19.98:3.56 (T7), which were more than the total fresh weight of the control (T1) treatment 13.49 g / plant, 7.28 g / plant, and 5.54 g / plant; the top three nitrogen, phosphorus, and p...

Abstract

The invention relates to a method for balanced fertilization of phoebe bournei seedlings. The method comprises the following steps: S1, cultivating phoebe bournei seedlings, wherein a medium for cultivating the phoebe bournei seedlings is prepared by mixing red soil, vermiculite and sand uniformly according to the ratio of 6 to 2 to 2; S2, applying a fertilizer containing nitrogen, phosphorus andpotassium to the phoebe bournei seedlings, wherein the mass ratio of nitrogen (namely N) to phosphorus (namely P) to potassium (namely K) is 0 to 0 to 0, 0 to 13.32 to 3.56, 2.66 to 13.32 to 3.56, 5.32 to 0 to 3.56, 5.32 to 6.66 to 3.56, 5.32 to 13.32 to 3.56, 5.32 to 19.98 to 3.56, 5.32 to 13.32 to 0, 5.32 to 13.32 to 1.78, 5.32 to 13.32 to 5.34, 7.98 to 13.32 to 3.56, 2.66 to 6.66 to 3.56, 2.66to 13.32 to 1.78, 5.32 to 6.66 to 3.56; S3, obtaining the optimal ratio by conducting multiple times of regression analysis on of nitrogen, phosphorus and potassium fertilization amounts and the quality indexes of the phoebe bournei seedlings. The method can effectively promote height and diameter increase of phoebe bournei seedlings, biomass accumulation and seedling quality improvement of the phoebe bournei seedlings.

Description

technical field [0001] The invention relates to the field of fertilization of woody timber tree species, in particular to a method for balanced fertilization of Phoebe nanzi seedlings. Background technique [0002] Fujian [ Phoebe bournei (Hemsl.) Yang], also known as Phoebe, is a member of the genus Phoebe (Lauraceae). Phoebe ) large evergreen trees and subtropical evergreen broad-leaved tree species are endemic to my country. The texture of the wood is fine, the surface of the cut surface is smooth, smooth and beautiful, not warped, easy to process, and the wood has a unique aroma. It is a precious material for high-end furniture, building wood, carving crafts, and precision wood models. Fujian Nan is also regarded as the top grade among landscape ornamental tree species by the garden circle because of its straight stem shape and long-lasting fragrance. Therefore, Minnan has good economic, social and ecological value, which has attracted great attention. [0003] So f...
