Description

A kind of selenium-rich citrus plant implantation methods
Technical field
The present invention relates to application technical field, and in particular to a kind of selenium-rich citrus plant implantation methods.
Background technology
Citrus, belong to Rutaceae, including tangerine, mandarin orange, shaddock, orange, lemon etc., be mainly distributed in the world north latitude 35-degree with The region in south.The citrus fruit being generally known not is all Citrus, such as trifoliate orange and kumquat are belonging respectively to Poncirus and Fortunella. And having many wild species in Citrus, its fruit is not suitable for edible.
Citrus plant typically contains abundant vitamin C, beta carotene, citric acid, vitamin A, B family vitamin, alkene The nutrients such as class, alcohols, aldehydes.The mineral matter elements such as also magnesium, zinc, calcium, iron, phosphorus, potassium and inorganic salts, cellulose and pectin Deng.
The vitamin C and organic acid enriched in plant, there are obvious regulation and inhibitory action to human metabolism, can increase Strong Abwehrkraft des Koepers.Vitamin C and carrotene, the formation of carcinogen can be suppressed, moreover it is possible to softening and protection blood vessel, Stimulate circulation, reduce cholesterol and blood fat.The tuberculosis of cervical lymph nodes and Thyroid Gland Swell are treated, kills ichthyophagy crab poison.Sour water is washed away, is shredded Food is store after being decocted with salt, only nausea, go to float wind bad odor in stomach.Overeat and understand impariment of the liver gas, apprehensive heat.Eaten with together with meat, the number of people can be made Dizzy nausea.Soak after grinding, face spot acne can be controlled every night by applying.The very fragrant U.S. of sauce, vinegar is done, stomach bad odor can be dissipated after food, help digestion lower gas, goes General mood is floated in stomach.Store and eat with salt, only nausea, disease of relieving the effect of alcohol.The orange fourth that sugaring is done, it is sweet, and gas under energy dissolving phlegm, during sharp diaphragm is wide, solution Wine.
Chinese patent《A kind of citrus implantation methods of high yield》(number of patent application:CN201611180867.5 one) is disclosed The implantation methods of kind citrus, including seedling, site preparation, field planting, top dressing, harvesting are selected, this forensic science is reasonable, simple and easy, and management is convenient, Securely and reliably, the survival rate of mandarin tree is high, yield is high and production fruit is stable.Rich selenium fruit is the focus of people's research at present, but right Citrous research is very few.
