Selenium-enriched strawberry organic fertilizer and preparation method thereof

Abstract

The invention discloses a selenium-enriched strawberry organic fertilizer and a preparation method of the selenium-enriched strawberry organic fertilizer. Pine tree saw dust, a selenium-enriched ricehull powder, and a pig manure and urine mixture are biologically fermented, a processing waste of a marine product, a selenium-enriched edible mushroom dreg powder and a plant waste mixed powder are organically fermented, the mixture are finally mixed, thoroughly decomposed and fermented, the organic material is constantly decomposed and transformed and releases the energy in the form of high temperature, the fertilizer nutrient turns into effective state and quick acting state from ineffective state and sustained release state, the humification is promoted, the foul smell in the ingredient israpidly eliminated, the beneficial microorganism in the fertilizer is increased, and the fertilizer nutrient is strengthened. The selenium element in the organic fertilizer is constantly implanted inthe growth process of the strawberry, the selenium-enriched strawberry organic fertilizer is safe, environmentally friendly and efficient, is rich in physiologically active substances, nitrogen, phosphorus, potassium and microelements required for the strawberry, can resist the diseases and reduces the dose, the fertilizer efficiency lasts long, the utilization ratio of the fertilizer is high, the selenium content of the strawberry planted by using the organic fertilizer instead of the chemical fertilizer is up to 0.035 mg / kg, the shelf life of the strawberry is prolonged by 5-10 days, the cost is reduced, and the economic benefit is increased.

Description

【Technical field】 [0001] The invention relates to the technical field of selenium-rich strawberry organic fertilizer, in particular to a selenium-rich strawberry organic fertilizer and a preparation method thereof. 【Background technique】 [0002] Selenium is an essential nutritional mineral trace element for the human body. It has various functions such as anti-oxidation, detoxification, anti-cancer and anti-cancer. It has the reputation of "element of life" and "king of anti-cancer". A large amount of epidemiological data proves that selenium deficiency in the human body is not only a basic factor for the onset of Keshan disease, but also one of the important causes of Kashin-Beck disease. According to statistics, there are more than 40 countries and regions lacking selenium in the world, and 2 / 3 of the land in my country is the internationally recognized selenium-deficient soil, involving 22 provinces (cities, districts), among which Jiangsu, Zhejiang, Anhui and other pla...

AI Technical Summary

Problems solved by technology

[0004] At present, there is no unified standard for selenium content in food in my country, and there is no unified standard for selenium content and usage specifications for selenium-rich fertilizer products, which leads to chaos in my country's selenium-rich market, and uneven quality of selenium-rich food and selenium-rich fertilizers

The cultivation of selenium-enriched strawberries is achieved by applying more selenium-enriched chemical fertilizers to achieve a certain selenium content, so the application of more chemical fertilizers will firstly increase the cost of strawberry planting, secondly, directly affect the fruit quality of strawberry, and thirdly, will affect the quality of strawberries. have a certain impact on the environment
