Multi-element compound liquid selenium fertilizer for fruit tree trunk injection and preparation method thereof

Abstract

The invention relates to a multi-element compound liquid selenium fertilizer for fruit tree trunk injection. The multi-element compound liquid selenium fertilizer comprises the following components in parts by weight: 6-10 parts of nitrogen, 6-8 parts of phosphorus, 10-12 parts of potassium, 1-2 parts of magnesium sulfate, 3-5 parts of calcium nitrate, 0-2 parts of trace elements, 0.25-1.0 part of sodium selenite, 6.0-10.0 parts of yellow humic acid, 0.5-5 parts of sugar alcohol type matters and 45-60 parts of water. The multi-element compound liquid selenium fertilizer provided by the invention has the benefits that the fertilizer prepared by the invention is comprehensive and balanced in nutrient elements and scientific in components, can provide large, medium and micro nutrient elements required for normal growth of fruit trees and meets the demands on nutrients in the growth and development processes of the fruit trees in an omni-directional manner; synergistic and antagonistic effects among the elements are fully considered, the proportion among the different nutrient elements is coordinated, the absorption of the fruit trees for the nutrient elements and the transportation are promoted, the fertilizer utilization efficiency can be obviously improved, the crop growth is promoted, the stress resistance is enhanced, the fruit setting rate and the disease resistance are obviously improved, and the fruit quality is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizer and its preparation, in particular to a multi-component compound liquid selenium fertilizer for fruit tree trunk injection and a preparation method thereof. Background technique [0002] Selenium is one of the essential trace elements for humans and animals. Its main function is to remove peroxides and free radicals in the human body, improve the body's immunity, and inhibit the growth of various tumors. my country is a selenium-deficient country. 70% of the soil is in a state of selenium deficiency or selenium deficiency. Selenium deficiency can easily lead to myocardial infarction, Keshan disease and other diseases in the human body. However, only the organic selenium formed through biotransformation is the safe form of selenium for the human body. Therefore, supplementing selenium by eating selenium-rich agricultural products is an important way to achieve selenium supplementation for the hu...

Problems solved by technology

Since the 1970s and 1980s, this technology has been applied to the supplementation of trace or trace elements in fruit trees, such as the production of selenium- or iodine-enriched fruits by injection of selenium or iodine, but its application is still mostly limited to single elements lack of problem solving

[0005] The liquid selenium fertilizers currently on the market have the following problems: (1) most liquid selenium fertilizers are developed for foliar spraying, and there is a lack of liquid selenium fertilizer products for fruit tree trunk injection; (2) the interaction between different nutrients is easy to produce (3) The competition or antagonism between ions is not fully considered, which affects the absorption of crops, and the fertilizer effect is not ideal; (4) The combination of different nutrients is not reasonable and balanced, and it is easy to cause some problems when used for injection fertilization. Excessive concentration of an element will cause fertilizer damage to the tree
