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 take them out and drain them, put them in a snakeskin bag, put 15-20 cm deep water in the pot, heat to 75°C and turn off the heat, and then put them 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;

[0046](2) 5 days before transplanting, apply the soil conditioner o...

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 invention provides a planting method of selenium-enriched and zinc-enriched rice. The method includes the following specific steps: (1) soaking seeds in water, then taking the seeds out and drip-dried the seeds, steaming the seeds in a water bath, and planting the steamd wet seeds to produce rice seedlings; (2) before transplanting, applying a soil conditioner rich in selenium and zinc to thesoil to be used for transplanting; (3) transplanting the rice seedlings to the soil applied with the soil conditioner rich in selenium and zinc when the rice seedlings reach 20-40 cm; (4) when the transplanted rice seedlings reach a stage between tillering and jointing, applying a selenium-enriched foliar fertilizer; (5) irrigating rice after applying the selenium fertilizer and maintaining the soil being wet. The method provided by the invention increases the content of selenium and zinc in the soil, and prevents heavy metal ions from entering the rice, thus increasing the content of seleniumand zinc in the rice. And the using cost is low, the operation is simple, and the cultivating method can be extensively 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...
