Embodiment 1

[0030] Embodiment 1 organic selenium-rich rice planting example

[0031] In a rice planting base, according to the steps of cultivating organic selenium-rich rice seedlings according to the method of raising seedlings in seedling fields, 6 groups of seedlings were cultivated, and each group cultivated the amount of seedlings used for transplanting rice seedlings in a 5-acre field.

[0032] Control group: No. 1 seedling field was produced according to the conventional seedling raising and transplanting process. After the rice was harvested, random sampling was performed to detect the total selenium content and the proportion of organic selenium in the total selenium. The results are shown in Table 1.

[0033]Experiment 1 group: When the seedlings in the No. 2 seedling field were unearthed about 10cm, weigh 5kg of nano-selenium plant nutrients with the electronic scale, sprinkle them evenly on the seedling field, and then sprinkle water with a watering can to remove all the nano-...

Embodiment 2

[0040] Embodiment 2 organic selenium-rich rice planting example

[0041] In a rice planting base, according to the steps of cultivating organic selenium-rich rice seedlings according to the method of raising seedlings in seedling trays and mechanical transplanting, a total of 6 groups of seedlings were cultivated, and each group cultivated the amount of seedlings for mechanical transplanting of 5 acres of field. Do as follows:

[0042] Control group: 5 acres of rice were planted according to the conventional method of seedling tray raising and mechanical transplanting. After the rice was finally harvested, the total selenium content and the proportion of organic selenium in the rice were randomly sampled and tested. The results are shown in Table 2.

[0043] Experiment 1 group: According to the amount of mechanical transplanting in a field of 5 mu, uniformly mix the seedling soil and nano-selenium plant nutrient in a ratio of 1000:1, and then follow the conventional operation,...

Abstract

The invention discloses a selenium-enriched paddy seedling and a cultivation method thereof and produced organic selenium-enriched rice. The total content of selenium in each seedling is between 4.6 and 360 mu g when the selenium-enriched paddy seedling is transplanted. The method comprises the following steps of: adding a nano selenium plant nutrition agent into seedling raising soil in seedlingdisks or seedling raising fields at the paddy seedling raising stage; and cultivating the selenium-enriched paddy seedling by a paddy seedling raising method. The content of the selenium in the organic selenium-enriched rice is between 100 and 300 mu g / kg, wherein the organic selenium content is more than or equal to 80 percent. The rice is rich in selenium elements, and the whole content is unified. By the method, the proportion of organic selenium is improved, the problem of low stability of the content of the selenium in the rice which grows in different batches in the prior art is solved,the uniformity of the content of the selenium in the rice is ensured, and the standardized large-scale production can be realized.

Description

technical field [0001] The invention relates to a rice seedling for producing rice rich in organic selenium, and a cultivation and application method of the rice seedling. The utility model belongs to the field of agricultural fertilization and agronomic technology. Background technique [0002] Rice is the main food crop in my country, and the population whose staple food is rice accounts for about 50% of the total population. my country's rice planting area reaches 29.96 million hectares, with a vast distribution area. Due to historical reasons such as food pressure, my country's rice production used to aim at high yield, and paid less attention to the content of rice microelements. With the increasing living standards of residents and the development of foreign trade, the development of microelement-enriched rice technology will continue to grow. received more attention. [0003] Selenium, the element symbol Se, is an essential trace element for the human body and the a...
