Trace elements have an irreplaceable and important role in increasing plant production and improving quality, but ordinary metal salts of trace elements are easily solidified when applied to the soil, resulting in a serious reduction in their effectiveness, which is a world problem; with the progress of science and technology, many chelated metal compounds formed by chemical ligands, such as EDTA/EDDHA, have been brought into the market, but due to the lack of degradation of their ligands, their use has been restricted by laws and regulations issued by countries such as the European Union, which are more harmful. The EU and other countries have introduced relevant laws and regulations to limit its use; Angie's Yeast Bio-agricultural Technology Center research team spent several years research, yeast metabolites as a coordinating agent, through the complexation technology, the development of the yeast metabolite trace elements in the product not only break through the barriers to the use of elements, but also achieve a win-win situation for the economy and ecology.

I. Yeast metabolite "Magic of yeast metabolite"

1. "Golden liquid" of Plant Nutrition

Yeast metabolite is not a synthetic product, but a collection of active substances naturally secreted by edible yeast in the process of fermentation, which contains: more than 40% small molecule xanthohumic acid with molecular weight in the range of 800 Da; more than 10% 16 kinds of free amino acids; more than 5% free amino acids; more than 5% free amino acids; more than 5% free amino acids; more than 5% free amino acids; more than 10% free amino acids. Free amino acids; 5% or more of yeast polysaccharides that can activate plant disease resistance system; 5% or more of organic acids such as citric acid, succinic acid and other organic acids; in addition, there are nucleotides, vitamins, niacinamide and other growth factors required for plant growth.

2. Biomimetic Complexation

Such as EDTA/EDDHA chelate state metal salts of the process usually require high temperature and strong acid process, Angie's yeast metabolite trace element products, through the improvement of plant equipment, screening of more efficient catalysts, etc., the development of low-temperature spray-drying preparation of complexed state metal salt products, Fe²⁺/Mg² ⁺/Zn²⁺ and other di- and tri-valent metal salt ions preferentially form five-membered ring stabilized structures with organic functional groups such as carboxylic acid (-COOH) and phenolic hydroxyl (-OH) of xanthic acid, amino acids, peptides, and organic acids; and the low-temperature spray-drying technology retains the life-promoting properties of polysaccharides, vitamins, and other heat-sensitive substances on plants.

Ⅱ. Comparison of different products

1. Comparison of product indexes (functional substances contained in 1kg of product)

Table 1: Comparison of magnesium-containing raw materials and plant synergistic components

Table 2:Comparison of synergistic components of plants containing iron-based raw materials

As can be seen in Tables 1 and 2, the yeast metabolite magnesium or yeast metabolite iron of magnesium/iron content, are significantly higher than other organic trace elements products, and other synergistic substances composition and quantity are also more abundant.

2. Economic analysis (refer to China market price)

Table 3:Comparison of ton price of magnesium-containing raw materials

Table 4:Comparison of ton price of iron-containing raw materials

As can be seen from Table 3 and Table 4, the cost advantage of yeast metabolite magnesium or yeast metabolite iron is very obvious, and the cost per ton is 17.5%-50% of the cost of other organic state trace element raw materials.

Ⅲ.The performance advantages of trace elements in yeast metabolites

1. High compatibility: pH 3-10 stability; can be compounded with phosphate without precipitation, can be compounded with bacteriophage without causing attenuation of the number of viable bacteria;

2. A variety of synergistic components: complexing and ligand for the yeast liquid fermentation by membrane separation and purification of the material, food technology, green and safe, rich in a variety of bio-stimulants can be completely absorbed and utilized by the soil, without chemical.

3. The coordination site of yeast metabolite and divalent or trivalent metal elements, the complexation coefficient is higher than EDTA, amino acids and other chelating/complexing agents, so the number of divalent or trivalent metal elements adsorbed by yeast metabolite complexation is higher than that of other complexing agents under the same quality.

4. The yeast organic acid can enhance the ion channel regulating ability of the root cell, and the xanthic acid-metal element, amino acid-metal element and organic acid-metal element complexes can rapidly enter into the root surface of the plant. Complexes can quickly enter the plant root epidermal cells, through the vascular bundles from the xylem upward transport faster to reach the aboveground growth parts of plants.

Ⅳ. The yeast metabolite trace element product application effect (yeast metabolite magnesium as an example)

Table 5: Increase in the application of magnesium-containing raw materials compared with the application of composite fertilizers input-output ratio

By taking the average fresh weight of spinach as the main factor, the results of the evaluation of spinach yield of each treatment showed that, under the same input, the yeast metabolite magnesium compared to amino acid magnesium yingmu can increase the income of 180 yuan, compared to EDTA magnesium yingmu can increase the income of 5,715 yuan, compared to the sugar alcohol magnesium yingmu can increase the income of 10,620 yuan, compared to the heptahydrate magnesium sulfate yingmu can increase the income of 12,330 yuan, compared to the anhydrous magnesium sulfate Ying mu yield can increase income 11250 yuan, and the input-output ratio are higher than other treatment groups with the same input.

Except for the magnesium sulfate heptahydrate treatment group, the effect of increasing the application of magnesium-containing raw materials compared to the single application of compound fertilizer on the quality of spinach are improved, specifically in the chlorophyll content is higher, magnesium is the central atom of chlorophyll, reflecting the absorption and utilization efficiency of the organic complex state of magnesium is much higher than that of the inorganic magnesium-containing raw materials.
