Ancient tree rejuvenating nutrient solution and preparation method thereof

Abstract

The invention provides an ancient tree rejuvenating nutrient solution and a preparation method thereof, and relates to the technical field of the rejuvenation of ancient trees. The nutrient solution includes, by weight, 10-30 parts of potassium nitrate, 20-40 parts of ammonium phosphate, 5-20 parts of magnesium sulfate, 5-20 parts of zinc sulfate, 5-15 parts of copper sulphate, 4-10 parts of ammonium molybdate, 20-40 parts of potassium dihydrogen phosphate, 1-6 parts of EDTA ferric-sodium salt, 1-5 parts of boric acid, 3-12 parts of potassium iodide, 2-20 parts of indolebutyric acid, 5-15 parts of alpha-naphthalene acetic acid, 15-30 parts of radix euphorbiae lantu, 10-20 parts of common cnidium fruit, 10-20 parts of gerbera delavayi, 5-10 parts of radix Coix lacrymajobi, 5-10 parts of root of spiny raspberry, 30-80 parts of cane sugar, 0.1-0.5 part of vitamin, 2-7 parts of humic acid, and 4-8 parts of agricultural antibiotic. The preparation method of the nutrient solution is simple,and has good healing effects on problems of weak growing tendency of ancient trees, easy suffering of pest and disease hazards, slow wound healing, center of gravity deviation and unbalanced branch distribution.

Description

technical field [0001] The invention relates to the technical field of rejuvenation of ancient trees, in particular to a nutrient solution for rejuvenation of ancient trees and a preparation method thereof. Background technique [0002] Ancient and famous trees are extremely precious plant resources in our country and are also excellent cultural heritages. They are often associated with historical celebrities and places of interest. They not only have high economic, ornamental and research values, but also a symbol of social civilization. It plays an important role in the process of urban landscaping and urban construction and development. The main reasons for the decline of ancient trees are as follows: (1) With the growth of tree age, the physiological function declines, and the water and nutrients absorbed by the lower parts of ancient trees cannot meet the needs of the above-ground parts, which leads to the imbalance of internal physiology and the gradual decline of tree...
