Embodiment 1
[0050] The present embodiment takes 2.5-year-old pine trees as the implementation object of the controlled-release fertilizer.
[0051] 2.5-year-old pine trees were selected in the Honggu sub-field of Paiyangshan Forest Farm in Guangxi for sampling investigation. Three repeated experiments were set up in each group, and each survey quadrat (20m×20m) was measured with a girth ruler and an altimeter. For breast diameter and tree height, select a standard tree, then fell it, and then cut it according to the Monsic layering method, each 2m is a section, apply the forest tree whole tree nutrition method, and weigh the whole plant according to the root, trunk, branches and leaves respectively According to the fresh weight of each organ of the tree, take a small amount of representative samples according to each organ, weigh the fresh weight, bring it back to the room, dry it in the oven to a constant weight, weigh the dry weight, calculate the moisture content of each organ, and then...
Embodiment 2
[0087] In this embodiment, the 8.5-year-old pine tree is the implementation object of the controlled-release fertilizer.
[0088] 8.5-year-old pine trees were selected in the Honggu subfield of Paiyangshan Forest Farm in Guangxi for sampling investigation. Three repeated experiments were set up in each group, and each survey quadrat (20m×20m) was measured with a girth ruler and an altimeter. For breast diameter and tree height, select a standard tree, then fell it, and then cut it according to the Monsic layering method, each 2m is a section, apply the forest tree whole tree nutrition method, and weigh the whole plant according to the root, trunk, branches and leaves respectively According to the fresh weight of each organ of the tree, take a small amount of representative samples according to each organ, weigh the fresh weight, bring it back to the room, dry it in the oven to a constant weight, weigh the dry weight, calculate the moisture content of each organ, and then calcul...
