A kind of polymicrooxygen fertilizer for fruit trees and preparation method thereof

Abstract

The invention discloses a polymicrooxygen fertilizer for fruit trees and a preparation method thereof. The polymicrooxygen fertilizer for fruit trees is made of the following raw materials in parts by weight: 1-3 parts of zinc sulfate hydrate, 3-5 parts of sodium tetraborate hydrate, molybdenum hydrate Ammonium acid 0.1-0.5 parts, calcium magnesium phosphate fertilizer 8-10 parts, coal powder 7-10 parts, brown loam powder 30-40 parts, calcium peroxide 40-50 parts. The multi-micro-oxygen fertilizer for fruit trees of the present invention can not only prolong the oxygen release time but also provide a variety of nutrient elements. It is suitable for increasing oxygen in water-logged soil and slowly increasing oxygen in the deep soil, widening the application range of oxygen fertilizer and realizing Oxygenation in deep soil has important application value.

Description

technical field [0001] The invention relates to the technical field of production, processing and fertilization of fruit tree fertilizers, in particular to a polymicrooxygen fertilizer for fruit trees and a preparation method thereof. Background technique [0002] "Air" is one of the four elements that constitute soil fertility. Poor ventilation will limit soil gas exchange, reduce soil oxygen concentration, affect soil nutrient conversion, inhibit root respiration, and limit root absorption and utilization of nutrients, which is not conducive to healthy plant growth and Crop yield formation, etc. It will also cause hypoxic stress to plants, start anaerobic respiration, and anaerobic respiration will not only reduce the efficiency of assimilating substances to produce energy, but also produce a large amount of harmful reducing substances, which will affect the normal function of the root system, which is not conducive to plant growth, and even cause plant damage. die.

But in more cases, there is no water accumulation in the soil and no waterlogging occurs. In this case, the oxygen content in the upper layer of the soil is relatively high, but the deep layer of the soil is always in a state of oxygen deficiency, which obviously limits the expansion of the root system to the deep layer; and, Zinc-deficiency leaflet disease, iron-deficiency leaf yellowing, boron-deficiency fruit shrinkage and other deficiencies of fruit trees often occur when the deep soil has poor air permeability. There is no oxygen fertilizer suitable for deep soil

[0005] The patent "A Slow and Controlled Release Oxygen Fertilizer and Its Preparation Method" (Application Publication No.: CN102924176A) needs to add a chemical adhesive polyvinyl formal solution to make an ointment, and also needs drying and moisture absorption. The process is relatively complicated and the polyvinyl formal consumption accounts for 15%, the quality of sodium bentonite and calcium peroxide is 12:5, and the ratio of oxygen-releasing active ingredient calcium peroxide in the finished product is on the low side (less than 36%); Vinyl formal and sodium bentonite are used in large amounts, which leads to higher product costs; moreover, polyvinyl formal needs to be deionized, which further increases the cost

The patent "A Slow-release Oxygen Fertilizer Used in the Olive Fruit-growing Period and Its Preparation Method" (Application Publication No.: CN107417416A) also has a complicated production process, and its ingredients contain xylene, which is a carcinogen. Among them, there are safety risks to the environment, human body and plants, and the proportion of oxygen-releasing active ingredients in the finished product is lower (less than 20%)

The patent "New Type Slow and Controlled Release Oxygen Fertilizer" (Application Publication No.: CN105884540A) requires a special adhesive and needs to be wrapped with paraffin. Specific dosage is very important for product formation and effectiveness

The patent "A seedling oxygen-increasing fertilizer and its preparation method" (application publication number: CN106747948A) is mainly aimed at the oxygen demand of seedlings. Oxygenation

[0007] The production of these existing oxygen fertilizers requires the use of special adhesives, and the process is generally complicated

Moreover, these oxygen fertilizers require a large amount of liquid water to release oxygen well, that is, they are mainly applied to the surface or shallow layers of flooded soil; Less and difficult to release oxygen or oxygen release efficiency is very low
