Efficient micromolecular coated fertilizer beneficial to increasing content of anthocyanin in purple sweet potatoes and preparation method thereof

Abstract

The invention discloses an efficient micromolecular coated fertilizer beneficial to increasing the content of anthocyanin in purple sweet potatoes. The efficient micromolecular coated fertilizer is prepared from fermented soybean meal protein powder, fermented rice bran meal, decomposed woody plant powder, silicate bactericide, aedelforsite, pinewood-based biomass charcoal, fermented burdock residue powder, fermented Chinese cabbage residues, starch aluminum octenylsuccinate, amino-oligosaccharin, melatonin, sodium diethylhexyl sulfosuccinate, oleum fructus bruceae, fermented wheat bran, cured tea seed meal, dehydrated vegetable micropowder, collagen powder, prohexadione calcium, ammonium citrate, jasmonic acid methyl ester, phenylalanine, a proper amount of oxygen-enriched alkaline magnetized water and the like by weight. Functional micromolecular compounds containing ammonium citrate, jasmonic acid methyl ester, phenylalanine and melatonin are adopted in cooperation with a nutrient solution, main ingredients prepared from compost and outer-layer coating liquid for coating to prepare the fertilizer, so that the fertilizer has the advantages that dual release is achieved, rich nutrients are provided, the content of anthocyanin in purple sweet potatoes can be increased, and high-quality efficient cultivation of purple sweet potatoes can be achieved.

Description

technical field [0001] The invention relates to the technical field of vegetable fertilizers, in particular to a small-molecule coated high-efficiency fertilizer and a preparation method thereof which are helpful for increasing the anthocyanin content of purple sweet potato. Background technique [0002] Plants need nutrients for proper function and growth. Plant nutrients fall into two categories: macronutrients, which are consumed in relatively large quantities and can comprise from about 0.2% to about 4.0% by dry matter weight of plant tissue; and micronutrients, which are consumed in smaller amounts. Quantities are consumed and can range from about 5 parts per million (ppm) to about 200 ppm or less than about 0.2% dry weight. There are three basic pathways for plant uptake of nutrients: (1) simple diffusion, which moves passively through lipid bilayer membranes along a concentration gradient; (2) assisted diffusion, in which solutes or iron along a concentration gradien...

Problems solved by technology

[0005] Small molecular substances are like a double-edged sword. They can easily pass through the plant cell wall according to their own characteristics and properties, improve the new way of plant nutrient absorption, provide the nutrients needed by plants, and bring benefits. However, improper use will cause damage to the plant. Damage to plant cells. At the same time, small molecular substances have high solubility and high permeability characteristics, but also have defects and deficiencies that are volatile and difficult to control. How to realize the application of small molecular nutrients in the design of high-efficiency vegetable fertilizers has Significance
