Problems solved by technology

[0004] 1. The inorganic selenium source is the main source, and the absorption and utilization rate of crops is low, which may easily lead to soil pollution and damage to crop growth
[0005] 2. It often only has the effect of increasing the selenium source, and the function is single, and the cost of farmers' planting increases
[0006] 3. The fertilizer contains one or more non-degradable chemical substances, causing long-term environmental hazards

Abstract

The invention discloses nano-selenium amino acid foliar fertilizer and preparation method of the same. The nano-selenium amino acid foliar fertilizer contains the following components by weight: 15-20 parts of amino acid, 1-5 parts of nano-selenium, 1-2.5 parts of biodegradable surfactant and 6-12 parts of trace elements. The preparation method of the nano-selenium amino acid foliar fertilizer includes the steps as follows: fully mixing compound amino acid solution with reducing agent solution, adding selenium compound aqueous solution and standing for 1-3d after stirring the mixture to uniform, thus preparing nano-selenium solution; and then adding the compound amino acid solution, the biodegradable surfactant and the trace elements. In the invention, multiple defects of the prior art are overcome, the advantages of moderate reaction conditions, low material cost, as well as easy absorption and inversion by crops and low toxicity to biology and environment of products are realized, and long-period large-area application is available.

Description

technical field [0001] The invention relates to foliar fertilizer technology, in particular to a nanometer selenium amino acid foliar fertilizer and a preparation method thereof. Background technique [0002] Since selenium was first confirmed as an essential trace element for animals and human body in 1957, many scholars at home and abroad have conducted extensive research on it. It has been confirmed that selenium has a great relationship with tumors, cardiovascular diseases and aging, which seriously affect human health. Selenium deficiency in the body will lead to a series of diseases, such as Keshan disease, Kaschin-Beck disease and so on. The body's selenium supplementation can also be anti-virus, anti-allergic, anti-aging, anti-inflammatory, anti-cancer, anti-cell growth, anti-heavy metal poisoning (cadmium, mercury, etc.), anti-aflatoxin BI and benzanthracene, nitrosamines and other carcinogenic It can reduce the toxic and side effects of radiotherapy and chemother...
