Ferment humic acid organic selenium fertilizer and preparation method thereof

Abstract

The invention relates to a ferment humic acid organic selenium fertilizer and a preparation method thereof. The preparation method comprises the following steps: a, crushing celery into paste, charging 1 percent of selenium yeast after placing in a fermentation kettle in a ratio of the celery paste to brown sugar being 6 to 4, and fermenting for 24 hours at the temperature of 28 DEG C, wherein stirring is performed once every 2 hours; b, crushing garlic into mashed garlic, placing the mashed garlic and grain vinegar at a ratio of 1:1 into a reaction kettle, reacting at the temperature of 32 DEG C for 7 days; c, crushing water hyacinth into a paste, charging the paste and chicken manure with the ratio of 4:6 as well as 1 percent of fermenting flora in the fermentation kettle, fermenting for 24 hours at the temperature of 45-55 DEG C, and stirring once every other 0.5H; charging mixtures obtained in the steps a, the b and the c with a ratio of 20:30:50 in a neutralizing reaction kettle for reacting for 24 hours, and stirring once every other 0.5 H to obtain suspension which is the ferment humic acid organic selenium fertilizer, wherein the reaction temperature is 35 DEG C. The ferment humic acid organic selenium fertilizer has the functions of increasing the fertilizer efficiency, improving the soil, and degrading heavy metals in soil by above 40 percent, and is suitable for large-scale extensive application.

Description

technical field [0001] The invention relates to an enzyme humic acid organic selenium fertilizer and a preparation method thereof, belonging to the technical field of agricultural biological fertilizers and pest control. [0002] Background technique [0003] The main source of selenium obtained by economic crops is selenium in the soil. Selenium in the atmosphere is also one of the sources of selenium in plants. According to the selenium absorption capacity of plants, it can be divided into two categories: selenium-accumulating plants and selenium-non-accumulating plants. Selenium is Selenium accumulates essential trace elements for plants. Native selenium-accumulating plants always grow in soils containing available forms of selenium, up to several thousand micrograms of selenium per gram of soil, whereas plants of the same type growing near them have selenium-non-accumulating varieties, selenium is higher An essential nutrient element for plant growth. According to rese...

Problems solved by technology

1.0ug / g of selenium can significantly increase rice root activity at seedling stage and glutathione peroxidase (GSH-Px) activity at tillering stage and booting stage, and the nitrogen content and selenium content in the grain are significantly higher than those of the control, The empty grain rate is greatly reduced; the test of spraying selenium on the foliage of corn plants shows that not only the selenium content of the corn is increased, but also the yield is increased. 10.0ug / g sodium selenite significantly inhibits the growth of rice seedlings and GSH-Px at the tillering stage activity, but it has a promoting effect on the activity of the enzyme during pregnancy, but the grain emptying rate is significantly higher than that of the control, and the rice yield is reduced; the promotion effect of selenium on crop growth and yield may be due to the proper amount of selenium entering the plant body, peroxidation The increase of the enzyme activity increases the anti-oxidation ability of the plant, thereby improving the stress resistance and anti-aging ability of the plant, and ensuring the normal growth of the plant. Therefore, when planting rice, corn, wheat and other crops in low-selenium areas, apply An appropriate amount of selenium may increase yield; excessive selenium has toxic effects on crops, which may be due to the fact that selenium promotes the peroxidation in the body to dominate. Selenium can antagonize the toxicity of various harmful substances in the environment, such as mercury, lead, cadmium, Due to the toxicity of arsenic, silver and other substances, it is hopeful to use selenium as one of the ways to solve environmental pollution. Selenium is beneficial to the growth of crops, but excessive use becomes a fatal poison. However, selenium that exists in the state of organic selenium is It is non-toxic and does not have the toxicity of inorganic selenium. However, selenium fertilizers currently on the market are generally produced by chemical means. Selenium generally exists in the state of nitroselenium, sodium selenate and sodium selenite. If used improperly become a toxin
