Problems solved by technology

Selenium yeast is an organic selenium source obtained by adding yeast to the medium containing selenium through fermentation technology. Therefore, the method of leaf spraying may cause the selenium yeast solution to adhere to the surface of plant leaves, which is not conducive to sales

Embodiment Construction

[0024] The present invention will be further described below in conjunction with specific implementation examples. These embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0025] Selenium yeast was purchased from Angel Yeast Company (2000 mg / kg selenium content, Yichang, China), and the variety of cabbage was Chunfeng, which was purchased from Xingtai Zhengyi Branch.

[0026] 1. Cabbage seedling cultivation: Cabbage seedlings were raised on September 18, 2018 using a 32-hole plug tray substrate, and the cabbage seeds were sown on the plug tray substrate. The substrate was purchased from Shandong Shenxian Yimutian Agricultural Technology Co., Ltd. (organic matter ≥ 50%) , the ambient temperature for seedling cultivation is 25°C, the relative humidity is 70-80%, and the light is 100 μmol / m 2 / s, the photoperiod is 14 / 10 hours.

[0027] 2. Transplanting: When the cabbage seedlings grow to four to fiv...

Abstract

The invention discloses a selenium-enriched cultivation method for cabbages. Selenium-riched yeast solutions with different concentrations are adopted for root watering of the cabbages, the selenium-riched yeast solutions are watered once every 10 days, watering is conducted 4 times in total, experimental results show that when the adding concentration is 0.4 mmol / L, the total selenium content inroots, leaves and balls of the cabbages reaches 25.96 mg / kg DW, 21.73 mg / kg DW and 19.09 mg / kg DW respectively, and plants grow well; and according to the cultivation method, growth of the cabbages ispromoted, the quality of the cabbages is improved, the selenium content of the cabbages is increased, the effect of selenium-enriched cultivation is achieved, meanwhile, the content of glucosinolatein the cabbages is increased, and the cultivation method has important significance for cultivation of the selenium-enriched cabbages.

Description

technical field [0001] The invention relates to a method for cultivating selenium-enriched cabbage. A certain concentration of selenium yeast solution is applied to the root of the cabbage to make the cabbage absorb and transform selenium, and make the cabbage grow normally, thereby obtaining selenium-enriched cabbage. [0002] technical background [0003] Cabbage (Brassica oleracea L.), a vegetable of the cruciferous family, is widely grown around the world due to its rich dietary fiber, minerals, carotenoids, vitamin C, folic acid, and glucosinolates. Selenium is one of the essential trace elements for humans and animals. It is of great significance to the health of humans and animals. In recent years, selenium fortification of plants through cultivation measures is of great significance for increasing the selenium content in vegetables and improving the selenium deficiency of the human body. . [0004] Cabbage has a certain selenium enrichment ability. Appropriate concen...
