Problems solved by technology

Disadvantages of cultivating (selenium-enriched) garlic in this method: During the entire growth period of garlic, high-selenium culture solution is supplied, and the characteristics of absorbing and accumulating selenium and selenium tolerance of garlic in different growth periods are not considered, resulting in selenium poisoning in the seedling stage, and the yield of garlic is significant. Reduced, selenium cannot be fully utilized, and it will cause environmental pollution after being discharged with the culture medium
When we sampled and analyzed high-selenium areas in China, we found that the selenium content of garlic and garlic sprouts harvested from the soil that has been extensively burned with high-selenium coal crucible slag or fumigated soil using high-selenium coal crucible for many years is also high , the method of cultivating (enriched selenium) garlic has the disadvantage of being difficult to reach the level of selenium content for health care or medicine; Suffering from diseases such as demethylation and hair loss caused by selenium poisoning, in recent years, most high-selenium areas have stopped using local coal crucibles for heating or smoky soil to prepare fertilizers

Embodiment 1

[0024] Adopt common hydroponic facilities, do selenium fertilizer with the selenium-containing Hoagland (Hoagland) hydroponic complete nutrient solution containing sodium selenate and be that 40% chemically pure sodium selenate mixes with selenium content, get 2.5mg sodium selenate Dissolved in 1 liter of Hoagland's complete nutrient solution for hydroponic cultivation, it can be formulated into a complete nutrient solution for Hoagland's hydroponic cultivation containing selenium with a selenium content of 1mg / L. Apply different concentrations of hydroponic liquid in different growth stages of garlic, and the selenium content is as follows: seedling stage, 5mg / L (that is, 12.5mg sodium selenate / 1 liter of hydroponic complete nutrient solution); plant rapid growth stage, 100mg / L (i.e. 250mg sodium selenate / 1 liter hydroponic complete nutrient solution); flower bud differentiation period, 50mg / L (i.e. 125mg sodium selenate / 1 liter hydroponic complete nutrient solution); after b...

Embodiment 2

[0026] According to the usual planting time of garlic and garlic sprouts, the cultivation procedures of sowing, thinning, and fertilization are carried out, including mixing the analytically pure sodium selenite with the commercially available Japanese garden test standard general hydroponic nutrient solution to prepare a hydroponic solution containing inorganic selenium Make single selenium fertilizer, get 2.23mg sodium selenite (selenium content is 45%) and dissolve in 1 liter of Japanese garden test standard general hydroponic nutrient solution, can be formulated into the selenium content that is 1mg / L containing selenium hydroponics Nutrient solution; adopt common hydroponic facilities and common hydroponic process to cultivate (comprising processes such as passing into air in the hydroponic nutrient solution, keep the hydroponic condition of sufficient supply of oxygen required for its root growth during the whole growth period of garlic ); including the following steps: ...

Embodiment 3

[0034] Carry out the cultivation procedure of sowing, thinning and fertilizing according to the usual planting time of garlic and garlic sprouts, and use sodium selenite and commercially available Hoagland (Hoagland) hydroponic complete nutrient solution to make a hydroponic solution containing inorganic selenium. A single selenium fertilizer is cultivated by common hydroponic facilities and common hydroponic techniques (comprising processes such as passing air into the hydroponic nutrient solution to keep the sufficient supply of oxygen required for the growth of garlic roots during the entire growth period) condition); includes the following steps:

[0035] (1) At the seedling stage, sodium selenate and commercially available Hoagland (Hoagland) hydroponic complete nutrient solution are used to make the Se amount containing inorganic selenium: 50 mg / L (i.e. 111.5 mg sodium selenite / 1 liter of hydroponic nutrient solution); adopt the mode of changing the selenium fertilizer h...

Abstract

A method for cultivating Se-enriched garlic cloves and garlic bolts features that beside conventional cultivation steps including sowing, thinning out seedlings, applying fertilizer, etc or use of water culture procedure, the sodium selenite (or selenate) and nutritive liquid are mixed to obtain the liquid selenium fertilizer, which has different concentrations of inorganic selenium for different growth phases. Said garlic cloves and garlic bolts feature their health-care function.

Description

technical field [0001] The invention relates to a plant cultivation method of garlic and garlic sprouts, in particular to a plant cultivation method of selenium-enriched garlic and selenium-enriched garlic sprouts. Background technique [0002] Recent studies by the Chinese Academy of Preventive Medicine and foreign reports have shown that selenium-enriched garlic can more effectively prevent gastric cancer, breast cancer, atherosclerosis and other diseases than ordinary garlic, such as literature 1: Ip.C. et al. "Mammarycancer prevention by regular garlic and Selenium-enriched garlic" (Nutrition and Cancer. 1992, Volume 17, No. 3, Page 279-286) described: Selenium in selenium-enriched garlic is the material basis for improving the disease-preventing activity of garlic. At the same time, selenium-enriched garlic Selenium also exhibits low toxicity. This indicates that selenium-enriched garlic is a carrier of natural selenium compounds with high e...
