CN102428809A - Selenium-enriched melon and production method thereof - Google Patents

Abstract

The invention discloses a selenium-enriched melon and a production method thereof. According to the production method of selenium-enriched melon, on conventional management conditions, selenium-enriched biological agent is sprayed on the leaves of melon every 6-8 days from the fifth day after pollination of the melon, 3-5 times in total and 100ml each time; and thus, the selenium-enriched melon fruits are obtained. In the production method provided by the invention, since inorganic selenium is converted into organic selenium through microbial treatment and then spayed on the leaves of plant, environment pollution caused by direct supplement of inorganic selenium such as sodium selenite in the traditional method can be overcome, the no-pollution sustainable development of production of selenium-enriched agricultural products can be realized, selenium content in melon fruits can be enhanced effectively, and selenium content in fresh of melon is high up to 0.59-0.63mg/kg, which has positive meanings for improving selenium level of people and preventing and treating diseases.

Description

A kind of rich selenium muskmelon and production method thereof

Technical field

The invention belongs to functional agricultural product production technical field, particularly a kind of rich selenium muskmelon and production method thereof.

Background technology

Selenium is the essential micronutrient element of animal and human's class.The international selenium recommendation daily intaking amount 60-400 μ g of association, daily intaking amount 50-200 μ g recommends in Chinese Soclety of Nutrition.And according to China's nutrition survey, the selenium intake of being grown up every day is 26-32 μ g only.Therefore, the population of China selemium nutrition is bad is common problem.China lacks selenium soil and accounts for 72% of national area, lacks selenium population and reaches more than 100,000,000.The many regional characters of China disease occurred frequently, as Keshan disease, Kaschin-Beck disease, cancer, cardiovascular and cerebrovascular disease, diabetes, sterility, immunity of organisms go down with aging course etc. 40 surplus kind of disease all with meals in the selenium picked-up not enough relevant.In addition, day by day under the serious situation, selenium has special physiological functions such as the heavy metal poisoning of releasing in environmental pollution.Therefore, human body is mended the requirement that selenium does not still improve immunity, also is the effective way that strengthens the resistance of environmental poisonous substance.

At present; " selenium yeast " of U.S. exploitation, kind deposit (Centrum) selemium nutrition additive and domestic " rich selenium health ", " health must selenium " though etc. product belong to biological technology products; But do not meet the food consumption present situation that large tracts of land lacks the selenium crowd, more can not become effective the replenishing that lacks the human selemium nutrition in selenium area.The academician such as Lu Liangshu, Li Zhensheng are pointed out, improving food chain selenium level is the basic outlet of regulating and control selemium nutrition and the relevant selenium deficiency disease of prevention from the source, and appeals to strengthen the Se-rich farm products exploitation; Through common crop production selenium is organised, set up the human selemium nutrition pattern of daily food intake, strengthen rich selenium food production; Have important commercial and economic worth, and build up people's health especially, (Lu Liang pardons the academician to the needs of protection people ' s health; The pollution-free food communication, on June 20th, 1999).

Muskmelon is claimed sweet melon or muskmelon again, and annual trailing plant originates in African tropical desert area, after the Middle East, the Central Asia, India are imported in Egypt, imports China into after again.Muskmelon is because of sweet the gaining the name of distinguishing the flavor of, because delicate fragrance is attacked the people so have another name called muskmelon, fruit is fragrant and sweet, is rich in sugar, starch, also has a small amount of protein, mineral matter and other vitamin.Because its distinctive fragrance and tasty and refreshing mouthfeel, it becomes the snacks fruit that summer, people liked with watermelon.At present, China's functional health muskmelon still belongs to the market vacancy, develops rich selenium muskmelon concerning the scarce selenium crowd in the scarce selenium area that accounts for nearly 2/3rds areas in the whole nation, and prospect for sales is good.

Summary of the invention

The purpose of this invention is to provide a kind of rich selenium muskmelon and production method thereof, to satisfy the market demand of people to Se-rich farm products.

For realizing above-mentioned purpose, the technical scheme that the present invention adopts is following:

Under the Routine Management cultivation condition, from muskmelon pollination the last the 5th day, utilize the Se-enriched bio preparation that muskmelon is carried out foliage-spray, each consumption 100ml whenever sprayed once at a distance from 6-8 days, sprayed 3-5 time altogether, obtained rich selenium melon fruit.

The application process of said Se-enriched bio preparation is: per 1 part of Se-enriched bio preparation sprays after adding 500 times of dilutions of water.

The manufacture craft of said Se-enriched bio preparation comprises the steps:

(1) by weight, pig manure 2-3 part or chicken manure 0.5-1 part, sheep excrement 1-2 part, colza cake or soybean cake 0.5-1 part, the former dew of EM 0.05-0.1 part are dropped into fermentation vat, add water 1-2 part, add a cover fermentation 30-40 days, to there not being stink;

(2) add water 8-9 part, continue fermentation 20-40 days, the solid constituent to batching dissolves;

(3) get zymotic fluid 100-200 order and filter, get Se-enriched bio preparation mother liquor;

(4) press the 100L mother liquor and add sodium selenite 5-10kg, dissolve and stir, do not have deposition, after reacting completely the Se-enriched bio preparation.

Beneficial effect of the present invention: (1) is through being converted into organic selenium with inorganic selenium through microbiological treatment; Spray again in plant leaf surface; Overcome the environmental pollution that traditional inorganic seleniums such as directly additional sodium selenite cause, accomplished the nuisanceless and sustainable development of Se-rich farm products production.(2) can effectively improve the Se content in the melon fruit, its pulp selenium content reaches 0.59-0.63mg/kg, is applicable to that China lacks selenium or use in low selenium area, to improve crowd's selenium level, preventing and curing diseases has positive effect.(3) raw material sources of Se-enriched bio preparation are abundant, produces easy, also lower with the cost increase of its production Se-rich farm products.
