preparation example Construction

[0053] Such as figure 1 Shown, the preparation method of the novel selenium-enriched peanut fertilizer additive that the embodiment of the present invention provides comprises the following steps:

[0054] S101, take 112 parts of concentrated molasses fermentation powder, 58 parts of citric acid, 10 parts of urea, 2 parts of sodium selenite, 4 parts of growth regulator (commercially purchased) and 9 parts of mineral nutrients by weighing equipment using electronic scales , 22 parts of peanut shells, 5 parts of clay, 0.5 parts of polypropylene glycol, 2 parts of EM bacterial agent (commercially available), 3 parts of banana peels, 4 parts of watermelon peels, 4 parts of pine needles, 1.8 parts of soybean pods, 1.5 parts of sodium nitrophenolate , 3 parts of sweet potato seedlings, 4 parts of plantain, 1.8 parts of honeysuckle, 1 part of Daphne chamaejasma, 0.4 parts of malic acid (commercially available), 2 parts of dicyandiamide (commercially available), 3 parts of soluble chi...

Embodiment

[0079] (1) Site preparation: select sandy soil, oil-sand soil, deep plowed soil, flat terrain, convenient irrigation and drainage, suitable soil structure, PH6; apply 1500 kg of organic fertilizer per mu, 2 kg of urea, use the prepared selenium-enriched peanut fertilizer, 40 kg per mu;

[0080] (2) Sowing: In the middle and late April, the whole ground row ditch will be opened, and peanuts with large and full grains without damage will be sown on-demand in the row ditch, and then a little soil will be covered on the row ditch on the peanuts;

[0081] (3) Management from growth period to blooming period;

[0082] a, 1 month after emergence, fertilize peanuts;

[0083] b. After the peanuts bloom, weed the peanut field, and loosen the soil between the peanut rows; and first prepare a high-purity sodium selenite aqueous solution, stir well, and spray evenly on the peanut leaves 10-15 days after loosening the soil , After an interval of 15 days, use this method to spray for the s...

Abstract

The invention belongs to the technical field of preparation of fertilizers, and discloses a novel selenium-rich peanut fertilizer additive and a preparation method thereof. The preparation method comprises the following steps: weighing components of the novel selenium-rich peanut fertilizer additive with an electronic scale; evenly stirring through a stirrer to obtain a mixture; implementing thermal cracking and carbonizing with a heater, cooling, and grinding; sieving grinded peanut shells with a sieve to obtain biomass charcoal; treating the biomass charcoal through a hydrochloric acid solution and irradiation to obtain a mixed modified material; mixing to obtain a compound insecticide solution; and evenly mixing the mixture with the mixed modified powder, the compound insecticide solution and the other raw materials. A fertilizer provided by the invention is good in fertilizer efficiency and is strongly targeted, nutrients are rapidly absorbed, the defect of insufficient nutrient absorption of a root part is overcome, the fertilizing method is simple and feasible, the economic benefits are remarkable; sodium selenite instead of sodium selenate is applied in the selenium-rich fertilizer, so that a health threat of the fertilizer to a producer and a consumer is avoided.

Description

technical field [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a novel selenium-enriched peanut fertilizer additive and a preparation method thereof. Background technique [0002] Peanut, formerly known as groundnut, is a kind of nut with abundant production and wide consumption in my country, also known as "longevity fruit", "ground bean" and so on. Peanut is an annual herbaceous plant belonging to the family Fabaceae. The stem is erect or prostrate, 30-80 cm long, the wing petals are separated from the keel petals, the pods are 2-5 cm long, 1-1.3 cm wide, swollen, the pods are thick, and the flowering and fruiting stages are 6- August. Mainly distributed in Brazil, China, India, Nigeria and other places. Peanut is rich in nutrition, high in unsaturated fatty acid and protein, and rich in minerals such as calcium and iron. It is an important edible oil crop and plant protein source crop worldwide. Peanut oil can...
