Problems solved by technology

[0002] Pine trees can produce turpentine, which has strong emulsifying effect, good wettability, penetrating property and leveling property. Anti-foaming agent and wetting agent have very good economic benefits. At present, the production of pine rosin is mainly increased by chemically stimulating resin extraction. However, this method cannot increase the raw materials that produce rosin. The growth time is not long, and it cannot fundamentally Solve the problem of insufficient rosin output, and the rosin obtained by this method is not easy to clarify, and the product quality is not good

preparation example Construction

[0083] The preparation process of the pine slow-release fertilizer includes the following steps:

[0084] S1: Mix urea, diammonium phosphate, potassium sulfate, calcium chloride, magnesium sulfate, manganese chloride, copper sulfate, zinc chloride, sodium borate, yellow humic acid, potassium polyacrylate, diatomaceous earth, and add water and stir evenly To obtain a homogeneous mixture, which is granulated, dried, and cooled to obtain fertilizer granules;

[0085] S2: Use 16-50 parts of water to adjust the starch into a slurry, raise the temperature to make the system at 40-52℃, adjust the pH of the starch slurry to 8.5-10.2, then add phosphate and oxidant, and react at 200-400r / min for 12 -20min, then add the coupling agent, keep the rotation speed constant, continue to react for 16-30min to obtain a starch emulsion; mix the prepared starch emulsion with talc, bentonite, peat, potassium nitrate and 130-700 parts of water. Dry it at 40-55°C until the moisture content is 12%-18%, t...

Abstract

The invention discloses a planting method capable of improving the growth speed of pine trees and the yield of rosins, which comprises the steps of preparation before planting, planting, accurate fertilization, trimming and pruning, and pest control. According to the pine tree slow release fertilizer, the biological quality of various organs such as roots, stems, leaves, flowers, fruits and the like of the pine trees and the content of nitrogen, phosphorus and potassium of the various organs are accurately sampled and analyzed according to the nutrient absorption and utilization characteristics of the pine trees and a whole tree nutrient method applied to soil so as to scientifically calculate the absolute values and relative proportions of absorption and storage of a large amount of nutrients such as nitrogen, phosphorus, potassium and the like in the tree bodies, thereby calculating the scientific proportion of a large amount of element nutrient fertilizers (N, P and K) required by the pine tree fertilization, wherein the growth of the height of the pine trees is increased by 11.72% on average, the growth of the breast diameters of the pine trees is increased by 14.90% on average, the rosin content is increased by 24.21% on average; and the planting method has obvious promotion effects on promoting the growth and development of masson pine trees and improving the yield of therosin.

Description

Technical field [0001] The invention relates to the technical field of pine tree planting, in particular to a planting method that can increase the growth rate of pine trees and the yield of rosin. Background technique [0002] Pine tree can produce rosin, which has strong emulsification, good wettability, permeability and leveling. It can be used for washing, fabric dyeing and coatings, varnishes, oils and other solvents. It is also used as mineral flotation agent, alcohol denaturant, Anti-foaming agents and wetting agents have very good economic benefits. At present, chemical stimulation is mainly used to increase the output of pine pine resin. However, this method cannot increase the raw materials that produce rosin reaction. The growth time is not long and cannot be fundamentally To solve the problem of insufficient rosin output, and the rosin obtained by this method is not easy to clarify, and the product quality is not good. [0003] Nutrient supply is the material basis for...
