Strawberry fertilizer capable of activating fertility of soil and preparation method of fertilizer

Abstract

The invention discloses strawberry fertilizer capable of activating fertility of soil. The fertilizer is prepared from raw materials in parts by weight as follows: 200-210 parts of a molasses alcohol waste liquid, 6-7 parts of oxygen-rich starch, 1-1.2 parts of monoammonium phosphate, 0.8-1 part of sorbitol, 10-12 parts of bran powder, 12-13 parts of humus, 20-21 parts of coco coir, 8-9 parts of seaweed meal, 8-9 parts of sawdust, 8-9 parts of turfy soil, 400-410 parts of 95% ethanol, 800-810 parts of a sodium hydroxide solution with the concentration being 0.5 mol / L, a proper amount of a hydrochloric acid solution with the concentration being 1 mol / L, a proper amount of a 50% sulfuric acid solution, 2-3 parts of rare earth oxide, 5-6 parts of polyvinyl alcohol, 0.2-0.3 parts of carbon nanotubes, 0.2-0.3 parts of beta-cyclodextrine, 0.1-0.2 parts of tea polyphenols and 1-1.2 parts of microbial powder. The quality of strawberries can be improved through chelating of amino acid prepared from the molasses alcohol waste liquid and rare earth, the mechanical strength of a film can be improved through addition of the carbon nanotubes to a film coating liquid, the slow-release property of the film can be improved through added tea polyphenols, and besides, the fertilizer can regulate and control the physical structure of the soil and the fertility of the soil and is applicable to improvement of poor and degraded soil.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a strawberry fertilizer capable of activating soil fertility and a preparation method thereof. Background technique [0002] Rare earths have complex physiological effects during the growth of crops, which can not only solve the problem of lack of trace elements in the soil, but also promote the development of crop roots, promote the synthesis of chlorophyll, improve photosynthesis Activity, speed up material transformation, improve crop yield and quality. However, without chelating rare earth elements, the crop absorption rate is only a few thousandths, and the effect is very poor. According to the coordination bond theory of complexes, such elements can easily form stable chelate complexes with some ligands. In the fertilizer industry, ethylenediaminemethylacetic acid (EDTA) and citric acid are mostly used in the United States. EDTA has a strong chelating force ...

Problems solved by technology

[0003] Molasses alcohol waste liquid is a by-product of sugar production in sugar factories—molasses as raw material. It is a high-concentration organic wastewater produced during the fermentation process of alcohol production. It contains more organic substances, such as protein, sugar, etc. If it is not used and treated directly, It will not only cause a large waste of resources, but also increase the cost of treating molasses alcohol waste liquid due to the high load
