Technical Field

[0001] The invention belongs to the technical field of fertilizers and relates to an adjuvant and application thereof in fertilizer production and / or humic acid fermentation. Background Art

[0002] The existing production process of organic-inorganic compound fertilizer is to physically mix (mix) several materials in a certain proportion. Fertilizers produced by low-temperature physical mixing have low fertilizer conversion rate and poor fertilizer efficiency; poor water solubility of fertilizers and low crop absorption rate; poor material mixing uniformity and uneven fertilizer efficiency; high volatility of fertilizers and large fertilizer efficiency loss. If granulation is performed after high-temperature melting, the melting temperature is high. For example, the dissolution temperature of urea is 132.7℃. It is necessary to achieve the melting of various raw material components through high temperature and high pressure. The production cost is high, and the microorganisms in the fertilizer will also be killed during the high-temperature melting production process, affecting its fertilizer efficiency. Summary of the invention

[0003] The invention provides an adjuvant and application thereof in fertilizer production and / or humic acid fermentation, which can effectively activate humic acid and significantly reduce the melting temperature during the fertilizer production process.

The present invention also relates to the application of the auxiliary agent in humic acid fermentation, wherein 0.2-5% of the auxiliary agent is added to the humic acid for fermentation.

[0008] Furthermore, when the humic acid raw material is fermented, biomass carbon source, nitrogen source, vitamin B, seaweed and magnesium oxide are added, the moisture content of the fermented material is 30-50%, and the fermentation is piled for 10-20 days to obtain activated humic acid. The biomass carbon source can be tea seed cake, rice bran, The present invention also relates to the activated humic acid obtained according to the above application.

[0009] The invention also relates to the use of the auxiliary agent in fertilizer production for reducing the melting temperature.

[0010] Furthermore, it is added when the fertilizer raw materials are mixed, and the added amount is 1-3% of the mass of the fertilizer raw materials; after adding, the temperature is increased and mixed.

[0011] Furthermore, the melting temperature is 50-70°C.

[0012] The present invention has the following beneficial effects: 1. The adjuvant of the present invention is used for the fermentation of humic acid, which can activate the microbial flora in the humic acid ore powder and increase the content of fulvic acid. After being mixed with other fertilizer raw materials and added to the soil, the number of microbial flora in the soil is increased, and the utilization efficiency of the fertilizer is improved; the soil is activated and improved.

[0024] Application Case 1 Application of additives in activating humic acid According to the formula in Example 1 to Example 6, each raw material is taken, and water of 1 times the total amount of the raw material is added to mix to form an auxiliary agent solution. The obtained auxiliary agent solution ferments the humic acid ore powder. During the specific fermentation, 60.83g of humic acid ore powder is taken from each group, and 17.38g of tea seed cake, 17.38g of bran, 0.43g of urea, 2.61g of brown sugar, 0.02g of vitamin B, 0.04g of seaweed, 0.87 of magnesium oxide and 0.44 of auxiliary agent are added. After the materials are mixed, they are piled and fermented for 15 days. At this time, the materials are honeycomb-shaped, and the whole material is full of white mycelium to obtain the fermented humic acid.
