Problems solved by technology

At present, there are mainly two methods for the production of selenium-enriched cowpea in China. One is to spray selenite solution on the leaves, but this method has the disadvantages of large residual amount of inorganic selenium and low safety.
The second is to plant in natural selenium-rich areas. This method is difficult to quantify and control the selenium content, and there are geographical limitations, which is not conducive to large-scale standardized production

Embodiment 1

[0022] This technique is carried out in six steps, first carry out (1) sowing and raising seedlings: first the bottom soil of the seedbed is filled, covered with 10cm thick loam, the seeds of cowpea are dug and sowed with the row spacing of 60cm, the nest spacing of 10cm, and the specifications of deep 10cm. Sow 3-4 seeds in the nest, cover with fine soil about 4cm thick, water, and transplant with soil when the seedlings have a pair of true leaves; then proceed to (2) Manufacture of selenium-enriched fertilizer: put the organic material of selenium-enriched fertilizer into Pulverize in a pulverizer and stir evenly, then add selenium-rich fertilizer additive, add water while stirring, until it can be held into pieces by hand without dripping, then add lime to the material to adjust the pH value of the material to 6.7-7.3, and add 0.001 -0.01% of EM bacteria agent was added to the material, stirred evenly, and the material was covered with a plastic film, and the compost was fer...

Embodiment 2

[0024] Carry out embodiment 1 repeatedly by the same steps as described, the difference is: step (1) sowing and raising seedlings: the seeds of cowpea are dug and sowed with row spacing 65cm, nest spacing 30cm, deep 10cm specifications, and step (2) manufactures rich Selenium fertilizer: cover the material with a plastic film, and compost and ferment for 9 days. During the compost fermentation, turn the material once every morning and afternoon, add 0.00001-0.0001% yeast and 0.0001-0.005% bacillus to the material, and stir Evenly cover the material with a plastic film, compost and ferment for 6 days. During the compost fermentation, turn the material once a day in the morning and afternoon to obtain compost. Step (3) Apply selenium-rich base fertilizer to the site: choose deep soil. In the soil rich in organic matter and convenient for drainage and irrigation, apply selenium-rich fertilizer as the base fertilizer 9 days before planting, 25 kg per mu; step (4) harvesting: cowpea...

Embodiment 3

[0026] Carry out embodiment 1 repeatedly by the same steps as described, the difference is: step (1) sowing seedling raising: the seed of cowpea is with line spacing 70cm, nest spacing 50cm, the specification of deep 10cm digs a nest and sows, and step (2) makes rich Selenium fertilizer: cover the material with a plastic film, and compost and ferment for 10 days. During the composting and fermentation, turn the material once every morning and afternoon, add 0.00001-0.0001% yeast and 0.0001-0.005% bacillus to the material, and stir Evenly cover the material with a plastic film, compost and ferment for 7 days. During the compost fermentation, turn the material once a day in the morning and afternoon to obtain compost. Step (3) Base fertilizer implementation: Apply selenium-rich base fertilizer for site preparation: Select deep soil. For soil rich in organic matter and convenient for drainage and irrigation, apply selenium-rich fertilizer as the base fertilizer 10 days before plan...

Abstract

The invention discloses a production method of organic rich selenium cowpea, and relates to the technical field of agriculture; the method comprises the following steps: (1) sowing and seedling raising; (2) making a rich selenium fertilizer; (3) preparing the soil and applying the rich selenium fertilizer; (4) field planting; (5) field management; and (6) harvesting. The production method of organic rich selenium cowpea achieves the purpose of normal growth of the entire growth and development period of cowpea by applying the fertilizer once without applying other chemical fertilizers, thus saving the labor cost of applying fertilizers for many times, achieving the purpose of saving the labor cost as well as producing rich selenium cowpeas, and further reducing the dosage of the selenium fertilizer, reducing the potential environment pollution by applying the selenium too much; and the method has a wide application foreground.

Description

technical field [0001] The invention relates to the field of agricultural technology, more specifically, the invention relates to a production method of organic selenium-rich cowpea. Background technique [0002] Selenium is an essential trace element for the human body. It is an essential component of glutathione peroxidase in the body. Selenium has an antioxidant effect and is closely related to human health. Selenium can protect the heart, resist liver necrosis, prevent myopia and cataracts, detoxify, Improve immunity, delay aging and enhance reproductive function and other pharmacological effects. Selenium-enriched agricultural products are an effective way for the human body to supplement selenium. Therefore, selenium-enriched technology is a hot field for scientists to research and develop and put it into actual production. Cowpea, also known as long bean and bean, belongs to the leguminous plant and is an annual herb plant. Cowpea is rich in nutrients and has multipl...
