Nutrient solution for big trees

Abstract

The invention provides a nutrient solution for big trees. A method for preparing the nutrient solution for the big trees comprises the steps: an aqueous solution of compound amino acids is prepared, the compound amino acids are mixed with water so as to obtain the aqueous solution of the compound amino acids, and the aqueous solution of the compound amino acids is enabled to contain 1.3% to 2.0% (mass percent) of the compound amino acids; and in order to obtain the nutrient solution for the big trees, the obtained aqueous solution of the compound amino acids is mixed with the following ingredients by weight based on per liter of the aqueous solution of the compound amino acids: 0.75g to 0.85g of potassium nitrate, 0.9g to 1.0g of calcium nitrate, 0.15g to 0.16g of ammonium dihydrogen phosphate, 0.45g to 0.55g of magnesium sulfate, 0.015g to 0.025g of ferric sodium edelate, 0.0015g to 0.0025g of manganese sulfate, 0.0027g to 0.0031g of boric acid, 0.0002g to 0.00024g of zinc sulfate, 0.000048g to 0.000053g of copper sulfate and 0.000017g to 0.000022g of sodium molybdate. The nutrient solution for the big trees has the beneficial effects that the service restrictions to the nutrient solution for the big trees caused by environmental temperature are avoided, the growth of the big trees can be better promoted, and the disease resistance of the big trees is enhanced.

Description

technical field [0001] The invention relates to a nutrient solution, in particular to a large tree nutrient solution. Background technique [0002] Urban greening, transplanting and keeping alive big trees and old trees are often encountered problems. At present, the survival rate of big tree transplantation is low, and traditional root fertilization and irrigation can not significantly improve the survival rate of transplanting, but big tree infusion has higher efficiency , greatly improving the survival rate of tree transplanting. [0003] A Chinese patent discloses a tree nutrient solution with the authorized announcement number CN 103274871 B, which is composed of the following components by weight: 0.5-5 parts of potassium nitrate; 0.5-5 parts of calcium nitrate; 0.1-1 part of magnesium sulfate ; 0.1-1 part of ammonium phosphate; 0.1-1 part of potassium sulfur nitrate; 0.1-1 part of potassium dihydrogen phosphate; 0.01-0.1 parts of manganese sulfate; 0.001-0.01 parts ...

AI Technical Summary

Problems solved by technology

Although this nutrient solution discloses the use of amino acids as components, the disadvantages that still exist in this patent are: 1) the patent does not have a clear and specific meaning of percentage (the percentage of the solution can be expressed as: mass percent concentration, volume percent concentration, etc.) , so those skilled in the art cannot clearly know the specific content of amino acids; 2) lack of some macronutrients, the effect of nutrient solution is not good; points, cannot be clearly realized
