Efficient fertilizer beneficial to increasing carotenoid content of carrots and preparation method thereof

Abstract

The invention discloses an efficient fertilizer beneficial to increasing the carotenoid content of carrots. The efficient fertilizer is prepared from selenium-containing chitosan oligosaccharide, pyroligneous acid, succinylcholine, indolebutyric acid, table vinegar, sodium nitrophenol, medical stone powder, garlic powder, plant ash, casein, waterborne polyurethane emulsion, purple perilla seed cake micropowder, pepper leaves, acorus calamus leaves, zinc gluconate, casein, alginate fibers, ferric citrate, carboxymethyl cellulose sodium, decomposed rape seed cakes, wood chips, decomposed castor cakes, liquid paraffin, pentaerythritol, melatonin, carotenoid, a proper amount of slightly-alkaline small-molecular-group magnetized water and the like by weight. The adopted functional melatonin and carotenoid can assist in improving the quality of carrots, and meanwhile the fertilizer prepared from a nutrient solution, main ingredients prepared from compost and outer-layer coating liquid for coating in cooperation has the advantages that dual release is achieved, rich nutrients are provided, and efficient cultivation of high-quality carrots is achieved.

Description

technical field [0001] The invention relates to the technical field of vegetable fertilizers, in particular to a high-efficiency fertilizer which helps to increase carotenoid content in carrots and a preparation method thereof. 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 gradient are transported rapidly by transport proteins....

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
