Problems solved by technology

Most trace elements such as zinc, iron, copper, etc. will react with phosphorus to form precipitates, which cannot be used in drip irrigation fertilizers
However, the cost of trace elements chelated by chelating agents such as ethylenediaminetetraacetic acid (EDTA) is extremely high, which is not acceptable to farmers.
At the same time, ethylenediaminetetraacetic acid (EDTA) is difficult to degrade and will pollute the soil
Fourth, the vast majority of soil in Xinjiang is alkaline, resulting in poor bioavailability of many nutrients, which require acidic fertilizers to adjust
Microorganisms are easy to multiply in the organic nutrient solution and then enter the decline period, and the shelf life of the product is relatively short

Abstract

The invention provides a biological organic drop irrigation fertilizer and a preparation method thereof. The biological organic drop irrigation fertilizer is prepared from, by weight, 60-93 parts of macroelement fertilizer, 3-20 parts of water-soluble organic fungicide, 2-10 parts of amino acid chelated trace fertilizer, 1-8 parts of pH adjuster and 1-4 parts of adjuvant. The water-soluble organicfungicide is prepared from water-soluble organic matter and microbial fungus powder. The amino acid chelated trace fertilizer is prepared from amino acid and microelements. The adjuvant is prepared from anhydrous magnesium sulfate, ammonium triphosphate and magnesium stearate. The invention further discloses the preparation method of the biological organic drop irrigation fertilizer. According tothe biological organic drop irrigation fertilizer and the preparation method thereof, the prepared fertilizer can be used under a drop irrigation condition, inorganic nutrients, organic matter and beneficial microorganisms are supplemented at the same time, and the fertilizer is acidic fertilizer, and can meet the requirements for improving alkaline soil. The preparation method is simple in procedure and low in cost and energy consumption, the resource utilization rate is increased, and the environment is protected.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a bio-organic drip irrigation fertilizer and a preparation method thereof. Background technique [0002] Xinjiang is located in the northwestern border of my country, far away from the ocean and deep inland, surrounded by high mountains, and the moisture from the ocean is not easy to enter, forming an obvious temperate continental climate. Here, the temperature difference between day and night is large, the sunshine time is long, and the climate conditions are suitable for the growth of crops such as grain, cotton, melons and fruits. It is known as "the warehouse of cotton grain" and "the hometown of melons and fruits". However, the precipitation here is low, the soil salinization is high, and the soil organic matter content is low, all of which seriously restrict the development of agriculture in Xinjiang. [0003] Since the 1990s, water-saving drip irrigation technology ...
