Abstract

The invention discloses a selenium-rich seed-soaking and pregermination method for hybrid rice. The method comprises the following steps: (1) firstly, thinly spreading hybrid rice seeds on a drying pad or cement ground, drying for 1-2 days, frequently stirring so as to enable the drying degrees of the seeds to be consistent; (2) packing the dried seeds into a nylon mesh bag in which the weight of the seeds does not exceed 10kg, and soaking the seeds in a selenium-rich water solution, blasting fresh air into the selenium-rich water solution by virtue of a blast blower when soaking the seeds, soaking the seeds for 10-12 hours in the day, fishing out from water and putting the seeds at home, draining, ventilating and helping the seed carry out aerobic respiration; (3) soaking the seeds in the next day for 5-7 hours, putting the soaked seeds into warm water at 38-42 DEG C, soaking the seeds for 10 minutes, taking out, draining, and carrying out insulating pregermination, and inspecting once every four hours; (4) successfully pregermination after 2-3 days; and (5) after pregermination of sprouts, thinly spreading the seeds on the ground in a room, refining the sprouts, sowing in the sun, wherein the total selenium amount of the rice sprouts is 18.4-180 microg/plant in transplantion.

Description

The rich selenium presoaking and germinating method of hybrid rice

Technical field

The present invention relates to agricultural technology field, be specifically related to a kind of rich selenium presoaking and germinating method of hybrid rice.

Background technology

Rice is the staple food crop of China, and the whole nation is that the population of staple food accounts for 50% of total number of people with rice.China's Monitoring of Paddy Rice Plant Area reaches 2,996 ten thousand hectares, and distributed areas are vast.Due to historical reasons such as pressures, China's Rice Production past take high yield as target, lower to the attention degree of rice secondary element content, along with the development of raising and the foreign trade day by day of Living consumption, the rich trace elements technological development of paddy rice will be subject to more attention.

Selenium, symbol of element Se is a kind of micro elements needed by human, is the activated centre of glutathione peroxidase.There is anticancer, anti-ageing (anti-oxidant) and improve the biological property such as body immunity, antagonism heavy metal.Selenium in food chain is mainly derived from soil.Different regions Selenium in Soils content distribution is uneven, implements according to the poor selenium soil clue in local and carries out rich selenium work targetedly, and the Se content level optimized in food chain is an important directions of agricultural production research.There are the county of 72% (city) low selenium or scarce selenium in China, and Heilungkiang, the Inner Mongol, Gansu, Qinghai, Sichuan etc. seriously lack selenium area has Keshan disease, Kaschin-Beck disease to occur, certain cancers district occurred frequently (as Jiangsu Qidong City) Ye Shudixi district.Chinese Soclety of Nutrition recommends that every day per capita, selenium intake was 50-200 microgram.But the day selenium intake of China adult only has 26-32 microgram now, therefore, the situation that selemium nutrition is bad is at China's ubiquity.The data that WHO announces shows, the whole world has more than 40 country to belong to low selenium or scarce selenium area.

Selenium in agricultural product is totally divided into the large class of inorganic selenium and Organic Selenium two: the former comprises selenate, selenite etc., and inorganic selenium is poor for assimilation effect humans and animals, and greatly, improper use very easily causes selenosis to risk of toxicity; The latter mainly comprises the forms such as seleno-amino acids, selenoprotein, selenium polysaccharide, and concerning good absorbing effect humans and animals, toxicity is little, is more suitable for the requirement of mending selenium.Se-rich farm products is human body Selenium Supplement element effective way, and therefore, technique of enriched selenium is that scientists study is developed and is put to the hot fields of actual production.The critical role of paddy rice in resident's dietary structure, determines its Se content level and has a great impact whole people's selemium nutrition situation.

Summary of the invention

It is simple that technical problem to be solved by this invention is to provide a kind of method, the rich selenium presoaking and germinating method of the hybrid rice that practical effect is good.

Technical problem to be solved by this invention realizes by the following technical solutions:

A rich selenium presoaking and germinating method for hybrid rice, comprises following methods step,

1) first spread out thinly by hybrid rice seeds on solarization pad or on concrete floor, shine 1-2 days, duty is stirred, make seed drying degree consistent;

2) seed rice shone is loaded in nylon net bag, every bag of seed is no more than 10kg, be placed in the rich selenium aqueous solution and soak seed, while seed soaking, adopt fan blower to blast fresh air in the rich selenium aqueous solution, soak seed daytime 10 ~ 12 hours, then pulling out from water puts back in family, and then draining is breathed freely, and helps seed to carry out aerobic respiration;

The above-mentioned rich selenium aqueous solution is made up of the component of following parts by weight: deionized water 100 parts, Se-enriched yeast 10 parts, purple sweet potato cyanidin 10 parts, sodium selenite 5 parts, tealeaves alkaloid 1 part, soybean lecithin 2 parts, hydrolyzed silk protein 2 parts, 2 parts, peppermint juice, marine alga micro mist 2 parts, water-soluble potassium 2 parts, 2 parts, Chelating state zinc, chelated ferrous iron 2 parts, smear tea (rich selenium) 2 parts, cashew nut oil 2 parts, ginger juice 3 parts, chlorophyll juice 5 parts, preservative 1 part, castor oil 1 part; Said components mixed during preparation, mixture is made;

Above-mentioned chlorophyll juice is made up of the component of following parts by weight: green tea 10 parts, Chinese weeping cypress leaf 5 parts, 5 parts, the leaf of bamboo, dragon spruce 5 parts, 15 parts, Chinese ilex, photinia glabra 10 parts, spindle tree 20 parts, spend in vain continue wood 10 parts, 4 parts, liver moss, 5 parts, bletilla striata leaf, Maranta Arundinaceavar. variegata 5 parts, 5 parts, rhizoma arisaematis leaf, 5 parts, water spinach; During preparation, said components is cut off, with 40-50 DEG C of thermal water, soak 4-6 hour, with juice extractor plant blended and squeeze the juice, impurity screening, extract chlorophyll juice;

3) soak seed next day and get for 5-7 hour, be put in the warm water of temperature 38-42 DEG C, soak 10 minutes, taking-up drains, and carries out insulation vernalization, within 4 hours, checks once;

4), after 2-3 days, vernalization can success, and seed is when the time comes sprouted paddy, bud root, requires that standard bud root is than bud paddy long 1/3 or 1/2, as fruit bud paddy is longer than bud root, bud root lack of water is described, supplements moisture content in time, otherwise, bud paddy is shorter than bud root, the amount of carrying out bud, reduces moisture content;

5), after the vernalization of bud paddy, seed need thinly spread out on the ground of indoor, carries out refining bud, then robs fine sowing.

During transplanting, rice seedling is always with selenium amount to be 18.4-180 μ g/ strain.

The invention has the beneficial effects as follows: the present invention mainly solves the technology that peasant's presoaking and germinating exists, improve emphatically the technology of peasant's presoaking and germinating, reduce the improper economic loss caused of peasant's presoaking and germinating, reduce the burden of peasant, increase the selenium content of bud seedling, there is the value of popularization, application.
