Description
Technical field
The present invention relates to agricultural plantation technology fields, and in particular to a kind of implantation methods of selenium-rich rice.
Background technique
Rice is main most long one kind in one kind and Oryza of draft Oryza as grain, also known as sub-
Continent type cultivated rice.To be annual, gramineae plant, unifacial leaf, property happiness is warm and humid, and there are about 1 meter of height when mature, leaf is elongated, there are about
50 to 100 centimeter lengths, it is about 2 to 2.5 centimetres wide.Spending for rice is very small, and when blooming, arch can be presented in main spray, in end of the branch
Little Hua can be all held between 30 to 50 millimeters down, and most of self-pollination is simultaneously born seeds, referred to as spike of rice.The size of the general grain of rice is 5
It is long to 12 millimeters, 2 to 3 mm of thickness.It is native to China.It is one of world's staple food crop.Rice in China sowing face accounts for entirely
The 1/4 of state cereal crops, and yield then accounts for more than half.Cultivation history is 14000~18000 years existing.For important cereal crops；
In addition to edible caryopsis, can starch processed, make wine, vinegar processed, rice bran can refine sugar, extracts oil, extract furfural, for industry and pharmaceutical；Rice straw
For good feed and paper making raw material and braided material, rice sprout and rice root can hyoscines.
Selenium is the essential trace elements of the human body.Chinese Soclety of Nutrition by selenium element be classified as 15 kinds of nutrients needed by human it
One, it is a large amount of both at home and abroad clinical experiments have proved that human body selenium deficiency can cause the functional disturbance of certain vitals, lead to many serious diseases
Disease occurs.
Low selenium or selenium deficiency crowd are not only able to the generation of pre- preventing tumor, hepatopathy etc. by appropriate selenium-supply, and can be improved
Body immunity, the vitals normal functions such as the maintenance heart, liver, lung, stomach, prevents the generation of senile Cardial or cerebral vascular diseases.
Thus selenium-rich rice is increasingly becoming the hot spot of rice research, and existing selenium-rich rice was sprayed at rice earing flowering initial stage
Foliar fertilizer containing selenium, such fertilization mode selenium fertilizer consumption is big, and rice is unobvious to the assimilation effect of selenium element.
