Fruit tree multi-element nourishing emplastrum

Abstract

The invention relates to a multi-element nutrition plaster for fruit trees, which is applied to the trunk and bark fertilization of fruit trees and economic trees. The plaster consists of major elements, secondary elements and trace elements which are required by the growth of plants and compound amino acid, humic acid substances, pH buffering agent, penetrating agent and plant growth regulator, which are coated on a plastic laminating film or a waxed paper laminating film which is then covered with a layer of a wax-coated paper film, the size of which is the same as that of the laminating film so as to obtain the multi-element nutrition plaster for fruit trees. In addition, the major elements is provided by potassium nitrate, ammonium nitrate and monopotassium phosphate while the secondary elements and the trace elements are provided by corresponding salts such as ferrous sulfate, sodium selenite, calcium lactate, calcium propionate, zinc sulfate and boric acid. When in use, the duston the bark of trunks or branches is firstly cleaned by using dry cloth and the wax-coated paper film of multi-element nutrition plaster for fruit trees is ripped off and firmly pasted on the bark around the trunk.

Description

technical field [0001] The invention relates to a multi-element nutrition plaster for fruit trees, which is suitable for fertilizing the trunks and barks of fruit trees and economic trees. The invention also relates to a preparation method of the nutritional plaster. Background technique [0002] At present, fertilization outside the roots of fruit trees mainly includes methods such as foliar spraying, trunk injection and transfusion, and trunk drilling. These fertilization methods have received certain effects to varying degrees, but due to the limitations of the application methods, there are also various defects. The disadvantages of foliar spraying are low fertilizer utilization rate, high cost, large amount of labor, time-consuming and labor-intensive, short fertilizer effect period, slow effect, and repeated spraying; trunk injection infusion is slow, high drug cost, and large amount of labor , It is unfavorable for large-scale popularization; The tree stem drilling ...

Problems solved by technology

These fertilization methods have received certain effects to varying degrees, but due to the limitations of the application methods, there are also defects of one kind or another.

The disadvantages of foliar spraying are low fertilizer utilization rate, high cost, large amount of labor, time-consuming and labor-intensive, short fertilizer effect period, slow effect, and repeated spraying; trunk injection infusion is slow, high drug cost, and large amount of labor , which is not conducive to large-scale promotion; tree pole drilling operation is cumbersome and labor-intensive, which is easy to cause damage to the tree body, shorten the life of the tree, and is easy to be infected by diseases and insect pests due to damaged bark
