Seeing the growth of new seedlings is a way for fast-growing white wax suppliers to distinguish the growth ability of seedlings. It better reflects the quality of seedlings, and the size of growth reflects the coordination status and overall level of each part of the seedlings.

Therefore, the aboveground and underground parts of seedlings have a greater impact on it. The weight, total seedling weight, ground fresh weight and seedling height that play a major role in the growth of Shandong fast-growing ash trees are the contribution of dry leaf weight and fresh weight. Large, indicating that the needles of the Chinese pine are important in the growth of the new shoots of Fanmu, which is inseparable from the mineral bittersweet that the needles provide energy for the initial growth of the new shoots and transfer to the new shoots.

The major influences on the growth of new shoots of Platycladus orientalis seedlings are the stem distance, the fresh weight of the main root, the ratio of stem to root and the height of the seedlings. The leaf quantity index is not included. It can be seen that the dependence of Platycladus orientalis is not as strong as that of Pinus tabulaeformis in the early growth period.

From the perspective of the indicators of influence on the growth of the new shoots of larch, the difference between the morphological grade of the seedlings and the morphological size of the photosynthetic seedlings of the underground parts of the ash tree is the difference in the growth ability of the seedlings.

Therefore, the material growth ability of seedlings of different grades should be quite different. The net photosynthetic rate is the fixed amount of photosynthesis minus the amount of CO consumed by photorespiration and respiration, which directly reflects the material production capacity per unit leaf area.
