specific Embodiment 1

[0020] An organic fertilizer for producing selenium-enriched Luo Han Guo, which is composed of the following components in terms of mass percentage: sheep manure (33%), plant ash (15.5%), biochemical yellow humic acid (8.5%), diatomaceous earth (2.5%), Selenium mineral powder (2.5%), modified urea (6%), potassium sulfate (1%), superphosphate (5%), magnesium sulfate (9%), boric acid (9%), water retaining agent (2.5%) , Bacillus subtilis and yeast mixture (5.5%).

specific Embodiment 2

[0021] A preparation method of an organic fertilizer producing selenium-enriched Luo Han Guo, comprising the steps of:

[0022] 1) Pretreatment of selenium ore powder: (1) Weigh 200 g of selenium ore powder, put it in a pulverizer for crushing, and sieve it through a sieve with a fineness of 100 mesh, (2) Add the crushed selenium ore powder into aqua regia (The mixed volume ratio of nitric acid and hydrochloric acid is 1:3) 600 ml, heat at 90-100°C for 3-6 hours, rinse with 3L distilled water for 2-3 times, filter out insoluble matter, (3) Evaporate the solution to dryness , to obtain 25 g of water-soluble selenium with higher selenium concentration;

[0023] 2) Culture medium preparation: Measure 5 L of distilled water, weigh 50 g of tryptone, 25 g of yeast powder, and 50 g of sodium chloride, mix well, keep the pH at 7.0, and sterilize in a high-temperature pressure cooker at 121°C for 30 minutes;

[0024] 3) Seed fungus cultivation: Weigh 125 g of Bacillus subtilis and 375...

specific Embodiment 3

[0028] A method of using organic fertilizer for producing selenium-enriched grosvenor fruit: when spring opens, open a semicircular fertilization ditch 1.2 feet away from the base of the seed potato; apply the selenium-enriched grosvenor fruit organic fertilizer to each hole 2.0 kg; then transplant the Luo Han Guo seedlings, the selenium in the selenium-rich Luo Han Guo organic fertilizer can be released slowly, the roots of Luo Han Guo are developed, the absorption capacity is strong, and selenium can be slowly absorbed during the growth period, and no topdressing is required during the entire growth period of Luo Han Guo. Exogenous selenium.

Abstract

The invention relates to an organic fertilizer for producing selenium-rich Siraitia grosvenorii. The organic fertilizer consists of the following components in percentages by weight: 30% to 40% of sheep manure, 15% to 20% of plant ash, 8% to 10% of biochemical yellow humic acid, 2% to 5% of diatomite, 2% to 5% of selenium ore powder, 5% to 8% of modified urea, 1% to 2% of potassium sulphate, 4% to 6% of calcium superphosphate, 8% to 15% of magnesium sulfate, 8% to 15% of boric acid, 2% to 5% of water-retaining agent and 5% to 6% of bacillus subtilis and yeast mixed bacteria. Moreover, the invention also provides a preparation method of the organic fertilizer for producing selenium-rich Siraitia grosvenorii and a use method thereof. The organic fertilizer has the beneficial effects that the organic fertilizer is low in cost, simple and convenient in operation, once root application is needed in the whole period of duration, the labor production cost is reduced, the produced Siraitia grosvenorii is safe in quality and high in content of organic selenium, and the organic fertilizer and the preparation method and the use method thereof can be widely applied in selenium-shortage areas or selenium-rich areas.

Description

technical field [0001] The invention relates to the field of crop cultivation, and more specifically relates to an organic fertilizer for producing selenium-enriched Luo Han Guo and methods for preparing and using the same. Background technique [0002] Selenium is known as "the fire of life", "the king of anti-cancer", "the patron saint of the heart" and "natural antidote". Long-term selenium deficiency or low selenium in the human body can cause more than 40 kinds of diseases, and adequate supplementation can be effective Improve the body's immunity. Selenium is an essential trace element for humans and animals. It has biological properties such as scavenging free radicals, anti-oxidation, anti-aging, anti-cancer, enhancing immunity, and antagonizing heavy metals. In 1988, the Chinese Nutrition Society recommended a daily selenium supplement of 50-250 micrograms, but the average daily selenium intake of Chinese adults is only about 17-32 micrograms, and selenium malnutrit...
