Example Embodiment

[0028] Example 1

[0029] according to figure 1 As shown, the present embodiment proposes a production method of green selenium-enriched nutritional rice, comprising the following steps:

[0030] S1: Choose a plot with flat terrain, drainage and irrigation openings, convenient drainage and irrigation, and no garbage pollution as the seedbed;

[0031] S2: comprehensively weed the seedbed, plough the land, make a border in a north-south direction, seal the border surface and drainage ditch, and spray the ground evenly;

[0032] S3: To prepare biomass selenium-containing fertilizer, first adjust the acidity of the seedbed soil, then apply biomass selenium-containing fertilizer to the seedbed, and mix well with the seedbed soil layer;

[0033] S4: Select the seeds, place the plastic film on a flat surface, spread the seeds evenly on the plastic film for drying, and then perform selenium-containing soaking, disinfection and germination treatment;

[0034] S5: Choose sunny weathe...

Example Embodiment

[0038] Embodiment 2

[0039] The present embodiment proposes a method for producing green selenium-enriched nutritional rice, comprising the following steps:

[0040] The selected seedbed is covered with vegetation and close to the fish pond.

[0041] Comprehensive weeding of the seedbed with glufosinate at a spray rate of 9L / hm 2, the spraying is carried out in sunny, cloudy, no wind and no rain; and in S2, when the ground is wet after rain, and there is no water in the ditch, spray with pendimethalin 300 times liquid on the border surface and drainage. The ditch is sealed with grass, and the surface is evenly sprayed to control the soil moisture ≥ 80%. Before fertilization, the method uses glufosinate to comprehensively weed the seedbed, and uses pendimethalin 300 times liquid to seal the border and the drainage ditch, so that the seedbed is free of weeds. The snatch of nutrients increases the selenium content of rice.

[0042] The specific process of preparing biomass s...

Abstract

The invention provides a production method of green selenium-rich nutritional rice, and relates to the technical field of rice production, and the production method comprises the following steps: S1, selecting a land parcel which is flat in terrain, has irrigation and drainage openings, is convenient for irrigation and drainage, and has no garbage pollution as a seedbed; s2, performing comprehensive weeding on the seedbed, ploughing the land, making furrows in the north-south direction, performing grass sealing treatment on furrow surfaces and drainage ditches, and uniformly spraying on the earth surface; s3, preparing a biomass selenium-containing fertilizer, and adjusting the acidity of seedbed soil; according to the method, a means of combining multiple selenium increasing is included, a biomass environment-friendly recycled material is adopted for increasing selenium and fertility of soil, a drying and selenium-containing soaking means is adopted, seeds are subjected to activated adaptation and partial absorption on selenium elements, seed germination is promoted, then in three stages of rice growth, selenium fertilizer is sprayed for three times, and the selenium fertilizer is sprayed for three times; the selenium can be fully absorbed by stems, leaves, flowers and fruits, and verification shows that the selenium content of the rice produced by the method is 150-185 mu g/kg.

Description

technical field [0001] The invention relates to the technical field of rice production, in particular to a production method of green selenium-enriched nutritional rice. Background technique [0002] Selenium was discovered in 1817, and was recognized by the World Health Organization in 1973 as "an essential trace element for human and animal life and vitality". More than 40 countries and regions in the world are deficient in selenium or low in selenium. In my country, 72% of the regions have a third of them. The second population lives in areas with low selenium or selenium deficiency. Selenium is closely related to human vitality. Selenium deficiency can lead to a high incidence of various diseases in the human body, such as cardiovascular and cerebrovascular diseases, hypertension, diabetes, Kashin-Beck disease, Parkinson's disease, There are more than 40 kinds of diseases such as cancer. Therefore, the World Health Organization recommends that the human body is supplemente...
