Ecological and organic corn fertilizer and preparation method thereof

Abstract

The invention discloses an ecological and organic corn fertilizer and a preparation method thereof, belonging to the technical field of fertilizers. The ecological and organic corn fertilizer containsurea, ammonium dihydrogen phosphate, potassium sulfate, zinc sulfate, vinegar residue, polylysine sodium, ferrous sulfate and dissolved pulp. The ecological and organic corn fertilizer is prepared through stirring, mixing and pulping. By utilizing polylysine sodium, ferrous sulfate and dissolved pulp for reinforcement, the yield of corns is increased, and the heavy metal absorptivity resistance of the corns is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to an ecological organic corn fertilizer and a preparation method thereof. Background technique [0002] The history of corn cultivation in my country is about 470 years. At present, my country's sown area is about 300 million mu, second only to rice and wheat, ranking third among food crops, and second only to the United States in the world. Widely cultivated in tropical and temperate regions of the world. Mainly farmyard manure, supplemented by chemical fertilizers. In my country, most of the corn is planted in hilly areas with thin soil and low fertility. Farmyard manure is mainly organic fertilizer, which contains rich nutrients, can improve soil, fertilize the land, and have a long fertilizer effect. Chemical fertilizers are quick-acting fertilizers. Although they also contain the nutrients needed by corn, compared with farmyard manure, the nutrients are stil...

Problems solved by technology

Hormone is a plant growth regulator added with artificial chemical synthesis, which has the function of dividing plant cells and stimulating plant growth. It is beneficial to some plants, but it cannot be used as a broad-spectrum type. It is not suitable for young crops, let alone perennial crops. and reserved crops

The mixed type is mostly a mixture of inorganic or organic compounds. Adding some nutrients can increase the yield of crops, but the disadvantages are: most of the products have odor or irritating odor, the effect of increasing yield is not obvious, and the performance is not stable enough. Insufficient stamina of fertilizer effect, the use concentration not only harms crops, but also lacks the ability to eliminate soil compaction. After application, the attached plant surface is not durable, easy to evaporate or lose, and the disease resistance is not strong

And now the pollution is serious, there are no heavy metal ions that can effectively prevent plants from absorbing the soil, and the benefits of fertilizers are single and not diversified

[0003] The Chinese patent document "A Corn Fertilizer (Patent No.: CN105859490A)" discloses a corn fertilizer and a preparation method thereof. In parts by weight, the content is: 40-45 parts of urea, 15-25 parts of humic acid, diphosphate 15-25 parts of ammonium hydrogen, 8-12 parts of potassium hydroxide, 7 parts of distiller's grains, 4 parts of zinc sulfate, 3-5 parts of sodium alginate solution, 0.5-0.7 parts of yeast chromium, and 4 parts of urease inhibitor. Fertilizer has relatively comprehensive nutritional elements, good fertilizer efficiency, strong pertinence, increased yield, and strong disease resistance, but it still needs to be improved
