Description
Technical field
The invention belongs to the technical field of planting fruit trees, about a kind of pear tree implantation methods being rich in selenium element.
Background technology
Selenium is the trace element of needed by human.Selenium participates in multiple selenoenzyme and Selenonic protein in synthesized human.Its Glutathione Peroxidase, catalysis hydroperoxides or MDA change water or various alcohols in vivo, eliminate the biomembranous attack of radical pair, and protection biomembrane is from oxidative damage; Selenium participates in forming iodate thyroid gland amino acid and takes off iodine enzyme.
Selenium can improve human immunity, promotes the synthesis of lymphocytic propagation and antibody and immunoglobulin.Selenium has kinds cancers such as colon cancer, cutaneum carcinoma, liver cancer, breast cancer and significantly suppresses and the effect of protection, and its mesostate methyl enol in body has stronger active anticancer.The nutrients such as selenium and vitamin E, allicin, linoleic acid, germanium, zinc have collaborative oxidation resistant effect, increase antioxidation activity.Meanwhile, selenium has the effect alleviating and alleviate heavy metal toxicity.
Organic Selenium can remove interior free yl, gets rid of vivotoxin, anti-oxidant, the generation that effectively can suppress lipid peroxide, prevents blood clot, remove cholesterol, strengthen immune function of human body.Selenium is the important element maintaining heart normal function, to the effect that heart human body has protection and repairs.The reduction of human body blood selenium level, the hypofunction of scavenging free radicals in body can be caused, hazardous material deposition is caused to increase, blood pressure raises, vascular wall is thickening, blood vessel elasticity reduces, VPV is slack-off, send oxygen function reduction, thus the incidence of disease bringing out cardiovascular and cerebrovascular disease raises, but supply Se scientific has good effect to prevention cardiovascular and cerebrovascular disease, hypertension, arteriosclerosis etc.
Scarce selenium is the Etiological of Keshan disease, Kaschin-Beck disease, two kinds of endemic illness, mends selenium and can prevent marrow end pathology, promotes to repair, and in protein synthesis, promotes that disulfide bond resists metallic element removing toxic substances.Good preventive and therapeutic action is had to these two kinds of endemic illness and arthritic.
The adhesion of selenium and metal is very strong, can resist the murder by poisoning of cadmium to kidney, gonad and nervous centralis.The heavy metals such as the mercury of selenium in body, lead, tin, thallium are combined, formed metallic selenium albumen compound and detoxify, toxin expelling.
In sum, " selenium " is needed by human, has no control over oneself again, and therefore World Health Organization's suggestion supplements 200 μ g selenium every day, can effective prevention of various diseases occurred frequently.
As the fruit being subject to extensively welcoming, pear is described as the ancestor of all kinds of fruits, and pears are fresh and sweet good to eat, delicious and crisp succulence not only, and nutritious.According to statistics, in the edible part of every 100 grams of pears, energy 167.5 kilojoule, about containing 0.1 gram, protein, 0.1 gram, fat, carbohydrate 9 grams, calcium 5 milligrams, 6 milligrams, phosphorus, iron 0.2 milligram, provitamin A (carotin) 0.01 milligram, vitaminB10 .02 milligram, vitamin B2 0.01 milligram, vitamin C 4 milligrams, 0.2 milligram, nicotinic acid.Pear have fall fire, clear away heart-fire, moistening lung, reduce phlegm, cough-relieving, bring down a fever, separate sore and wine poison effect, normal food can supplement the nutrition of human body.It is edible that pear is particularly suitable for hepatitis, pulmonary tuberculosis, constipation, acute and chronic tracheitis, the infection of the upper respiratory tract, hypertension, cardiopathy and esophageal cancer patients.
This homely fruit of pears is trained the product be rich in the useful selenium element of human body by one of the problem to be solved in the present invention exactly, and the present invention realizes by designing a kind of special selenium-enriched fertilizer for pears.
In prior art, there is the scheme using foliage fertilizer and soil fertilizer to apply selenium element.The shortcoming of foliage fertilizer is, is generally add inorganic selenium, and this causes blade face, fruit easily speckles with inorganic selenium, if do not clean, user may be caused poisoning.For soil and fertilizer, the technology in forward position is use earthworm bioaccumulation selenium the most at present, be translated into the selenium of the form-organic form easily absorbed, " sodium selenite is to the research of the toxicity of earthworm and vermis selenium enriching functions ", Liu Xianghui etc., application and environmental organism journal, 2001,7 (5)--prior art 1; " novel selenium-enriched fertilizer is on the impact of leek and quality ", Liu Jun etc., 2011,27 (16)---prior art 2; But earthworm causes becoming thin until dead along with Se content increase after by feeding bait, this is unfavorable for organism enrichment.
Fertilizer containing two large class Selenium Supplement elements in prior art, one is foliage fertilizer, directly by the fertilizer spray containing selenium element to blade face to reach the object of Selenium Supplement element, but because selenium element has certain toxicity, can not clean preferably may bring the impact being unfavorable for health to eater as fruits blade face.Another kind of fertilization mode and fertilizer are traditional clay fertilizers, and mixed in soil by fertilizer and absorbed by plant root, these class methods are similar to traditional fertilizer, are all to be incorporated in fertilizer by the material containing selenium element.
The fertilizer that the present invention prepares belongs to the latter, is namely directly applied to the fertilizer of soil.
Because inorganic selenium has higher toxicity, also be unfavorable for that plant absorption is preserved, therefore in prior art, have use earthworm bioaccumulation selenium element, and inorganic selenium is converted into the settling mode of Organic Selenium, but because earthworm breeding has, cost is high, raising condition is comparatively harsh and the inferior position of collecting not easily, therefore the present invention proposes following scheme:
Fertilizer of the present invention is prepared by following methods, and breeding cockroach, its kind is not limit, and adds containing selenium material, breed after adult, pulverized until cockroach in its young bait, and this powder can directly as the Fertilizer application containing selenium element.
One of them preferred embodiment, used is selenite, selenate, elemental selenium, selenides containing selenium material;
One of them preferred embodiment is, the addition containing selenium material is the 100-3000ppm of bait, preferred 250-700ppm, more preferred 300-500ppm;
