Problems solved by technology

[0003] In recent years, the public's awareness of the management of pine tending and fertilization has gradually increased, especially the investment in pine fertilization. However, due to the lack of understanding of the growth and development of pine trees and their fertilizer requirements, nitrogen fertilizers are applied more than phosphorus and potassium fertilizers. The selection of fertilizer varieties, application amount, fertilization time, and application methods are not well grasped. Fertilization is not scientific and the effect is not obvious

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...

Abstract

The invention discloses a pine tree controlled-release fertilizer for scientifically increasing yield and a preparation technology thereof and belongs to the technical field of fertilizer preparation.The pine tree controlled-release fertilizer for scientifically increasing yield comprises the following raw materials: urea, diammonium phosphate, potassium sulfate, calcium chloride, magnesium sulfate, manganese chloride, zinc chloride, sodium borate, fulvic acid, potassium polyacrylate, kieselguhr and coating material. The pine tree controlled-release fertilizer for scientifically increasing yield is prepared according to the following steps: pelletizing, drying, cooling, coating, and the like. According to the invention, the advantages of pine tree controlled-release fertilizer can be extremely utilized; cultivation of short-period industrial raw material forest of pine trees can be realized; the rotation period of industrial raw material forest of pine trees can be greatly shortened;mineral substances and nutrients brought by pine tree felling can be made up and nutrient balance of soil can be guaranteed; the maximal economic benefit can be acquired with the minimal fertilizer investment; the sustainable production of pie tree planting region can be realized.

Description

technical field [0001] The invention relates to the field of fertilizer processing, in particular to a pine controlled-release fertilizer for scientifically increasing production and a preparation process thereof. Background technique [0002] Pine trees are widely used and are the preferred tree species for timber forests and shelterbelts in my country. However, according to conventional methods, it generally takes about 15 years to become useful. In order to obtain a high growth rate in a short period of time, reasonable fertilization must be carried out, especially for afforestation land in southern barren soil. The effect of fertilization is very obvious, and fertilization is an important measure to create a high-yield pine forest. [0003] In recent years, the public's awareness of the management of pine tending and fertilization has gradually increased, especially the investment in pine fertilization. However, due to the lack of understanding of the growth and developme...
