Description

A kind of cultural method rich in Organic Selenium rape
【Technical field】
The present invention relates to technical fields, and in particular to a kind of cultural method rich in Organic Selenium rape.
【Background technology】
Rape is called pakchoi, bitter dish, Latin literary fame:Brassica campestris L. Cruciferae, Brassica genus are planted Object originates in China, and stem color is dark green, and side such as Chinese cabbage belongs to Cruciferae Chinese cabbage mutation, flower is yellow.It will be planted on agronomy Multiple species of seed oil-containing are referred to as rape in object.Rape Main Cultivation (kind) type is at present:Turnip type rape (Brassica rapa (campestris) L.), mustard type rape (Brassica juncea L.), cabbage type rape (Brassica napus rape nature and flavor are sweet, cold, nontoxic, contain abundant protein, fat, carbohydrate, inorganic salts, Yan acid, Hu Luo Bu Su, vitamin B1, B2, vitamin C etc., rape can be processed into a variety of homely dish, and because its mouthfeel is fine, nutritive value is high, at Most one of green vegetables are eaten for the common people.
Selenium plays special role in micro elements needed by human in the glycometabolism and lipid metaboli of body.Selenium-supply can not only The deposition for enough reducing cholesterol on aorta pays off removing and has been deposited on Supraaortic cholesterol, prevents arteriogenesis athero- Hardening.Selenium is the stabilizer of nucleic acid (DNA and RNA), can prevent the mutation of intracellular certain genetic stews and pre- anti-cancer.Selenium It can promote the utilization of glycine in liver, serine, methionine, thus the synthesis of protein can be reinforced.It can promote RNA in liver Synthesis, protects the structural integrity of RNA, from thermal denaturation.In addition, the selenium accumulated in nucleus has adjusting and changes the work(of gene Energy.Serum cortisol content increases when under animal spleen stress situation, and glucocorticoid is the class for inhibiting growth and immune system Sterol.Selenium can reduce serum cortisol content effectively inhibit stress, improve immunoglobulin content and antibody concentration come Enhance the immunity of animal.Animal selenium deficiency equally can also cause cholesterol or blood glucose rise, growth retardation immunity degradation, breeding Ability reduction and the lost of life etc., birds daily ration selenium content is less than 5 μ g/kg, and feather largely falls off.Kind of a public affairs are fed with no selenium feed Ox, semen volume greatly reduce, and rate of teratosperm significantly improves, and the above symptom disappears after selenium-supply.
It is generally believed that we only need micro selenium, then we can easily take in enough from diet Selenium.Perhaps it is being in this way, still many people selenium of the modern studies have shown that in us are all using coarse food grain as the age of Major Foods Intake ground is inadequate --- after this is because living material level improves, we have eaten the too many carbon hydrate finished Object, these finishing Selenium In Foods contents are seldom, this is why modern standard of living improves, and suffers from hyperglycemia, height The people of blood fat is more.We are also conceivable to supplement Organic Selenium.
Selenium is supplemented with two kinds of forms of inorganic selenium and Organic Selenium, and the biological activity of selenium needs trivalent selenium, due to not similar shape Combination degree is different in the tissue for formula selenium, causes absorptivity different.Inorganic selenium toxicity is big, and absorption is horizontal low, and human body is to inorganic selenium Absorption rate it is extremely low, less than 1%;Human body is to the utilization rate of Organic Selenium up to 10~25%.Normal adult's demand 20~ 50 μ g (microgram)/day, children, pregnant woman and old man are 50~110 μ g/ days, and diabetic and obese people are 50~200 μ g/ Day.Less to Organic Selenium research report beneficial to human body in rape at present, opposite plantation lack of standardization easily causes heavy metal pollution, Since rape is that people eat many green vegetables, in south, the very summer and autumn even common people eat a kind of most vegetables Dish, increases the nutritive value of rape while to reduce the problem of polluting during rapeseed cultivation significant to health of people.
【Invention content】
The goal of the invention of the present invention is:For problem low to the organic selenium content that human body is beneficial in rape, one is provided Cultural method of the kind rich in Organic Selenium rape, can effectively improve the content of Organic Selenium in rape, the nutriture value for increasing rape Value, while the rape that the present invention plants also has leaf tender stem crisp, the good feature of eating mouth feel.
To achieve the goals above, the technical solution adopted by the present invention is as follows:
A kind of cultural method rich in Organic Selenium rape, includes the following steps:
