Embodiment 1

[0042] Land selection: Select farmland with low zinc and selenium content and excessive heavy metal content for planting.

[0043] Seed selection: Select high-quality rice seeds.

[0044] A planting method of selenium-rich zinc-rich rice, the specific steps of the method are:

[0045] (1) First soak the above-mentioned high-quality rice seeds in water for 48 hours, then remove and drain, put them in a snakeskin bag, put 15-20 cm deep water in the pot, heat it to 75°C and turn off the heat, and then put it on the water surface of the pot Put a row of small wooden sticks at 3 to 5 cm, put seeds on top, keep the water temperature, and fumigate for 24 hours, then use an 80*45 plastic box, add appropriate amount of soil, water the soil, use water as a bed, moisten the seeds, and put them in the box after sowing The surface is covered with a layer of film, and the low arch is covered;

[0046](2) 5 days before transplanting, apply the soil conditioner of silicon, sulfur, selenium ...

Embodiment 2

[0064] Land selection: Select farmland with low zinc and selenium content and excessive heavy metal content for planting.

[0065] Seed selection: Select high-quality rice seeds.

[0066] A planting method of selenium-rich zinc-rich rice, the specific steps of the method are:

[0067] (1) First soak the above-mentioned high-quality rice seeds in water for 48 hours, then take them out and drain them, put them in a snakeskin bag, put 15-20 cm deep water in the pot, heat it to 80°C and turn off the fire, and then put it on the water surface of the pot Put a row of small wooden sticks at a distance of 3 to 5 cm, put seeds on top, keep the water temperature, and fumigate for 24 hours, then use an 80*45 plastic box, add appropriate amount of soil, water the soil, make a bed with water, moisten the seeds, and put them in the box after sowing The surface is covered with a layer of film, and the low arch is covered;

[0068] (2) 5 days before transplanting, apply the soil conditioner...

Embodiment 3

[0082] Control group: rice seeds were planted in the same farmland with excessive heavy metal content as in Example 1 according to the usual method, and the rice was harvested after the rice matured.

[0083] According to GB 5009.93--2010 and GB / T5009.14--2003, the selenium and zinc elements in the harvested rice in Example 1 and the control group were detected respectively, and the test results found that the selenium in the rice of Example 1 The selenium content was 0.29mg / kg, and the zinc element content was 23.2mg / kg. The selenium element content in the rice of the control group was 0.035mg / kg, and the zinc element content was 13mg / kg.

[0084] According to the planting method of a kind of selenium-enriched zinc-enriched rice in embodiment 1, then select the soil of different time (5d, 15d, 25d, 35d, 45d, 55d) to detect the content of Cd and As, the result is as follows figure 1 , it can be seen that the content of available Cd and As in the soil is basically close to zero...

Abstract

The present disclosure provides a method for planting selenium-rich and zinc-rich rice. The specific steps of the method are: (1) first soak the seeds in water, then remove and drain, and fumigate in a water bath, and then fumigate the seeds Seeds are sown in moisture to grow rice seedlings; (2) before transplanting, apply a zinc-rich and selenium-rich soil conditioner to the transplanted soil; (3) when the rice seedlings grow to 20-40cm, transplant the rice seedlings (4) Then, between the rice seedling growth after transplanting and the tillering stage to the jointing stage, apply selenium-enriched foliar fertilizer; (5) apply selenium-enriched fertilizer Afterwards, the rice is irrigated to keep the soil moist. The method increases the content of selenium and zinc in the soil, can block heavy metal ions from entering rice, enhances the content of selenium and zinc in rice, has low use cost, simple operation and can be widely used.

Description

technical field [0001] The disclosure belongs to the technical field of rice planting, and in particular relates to a method for planting selenium-rich and zinc-rich rice. Background technique [0002] Zinc and selenium are essential trace elements for the human body and elements for maintaining normal metabolism of human body functions. Zinc and selenium deficiency can lead to various diseases. Our country has a vast range of sources, and the basic composition of the diet is mainly grains. Insufficient zinc intake in food or too much fiber intake affects zinc absorption and leads to zinc deficiency. Zinc deficiency is more common in children. Selenium is a component of glutathione peroxidase and phospholipid hydroperoxide glutathione peroxidase. It has many important physiological functions, the most important of which is to remove excessive active oxygen free from the body. base. Selenium is a natural antidote for some heavy metal elements, which can eliminate the accum...
