Abstract

The invention discloses an organic selenium-enriched blueberry planting method. The method is characterized in that cardamine hupingshanesis containing selenium serves as a selenium source for preparing selenium-enriched organic matrix fertilizer, the selenium-enriched organic matrix fertilizer is used in the blueberry seedling culture process, a selenium-enriched organic matrix is applied and serves as base fertilizer before blueberries are transplanted, and the selenium-enriched organic matrix is applied and serves as additional fertilizer after the blueberries bloom and produce fruits. By the adoption of the method, a common method that a solution containing selenium or leaf fertilizer containing selenium is mainly sprayed in the blueberry blooming and fruiting stages in current selenium-enriched blueberry production is changed, unsafe factors existing in selenium-enriched tomato production are avoided, and the method is economical, efficient, free of pollution, capable of improving the selenium level of people and positive in significance in disease prevention and treatment.

Description

A kind of implantation methods of organic Se-rich blueberry

Technical field

The present invention relates to blueberry planting technology field, specifically a kind of implantation methods of organic Se-rich blueberry.

Background technology

Selenium, it is the necessary trace element of humans and animals, have protect heart and brain, protect the liver kidney, radiation proof, anticancer change, toxolysin, anti-ageing, recover the physiological function such as islet function and develop immunitypty, can effectively prevent 40 various diseases such as Keshan disease, Kaschin-Beck disease, cardiovascular disease, cancer, diabetes.The selenium intake that Chinese Soclety of Nutrition is recommended is 50-250 micro-gram/day, and AAN is classified as selenium as the life nutritional element of equal importance with vitamin, carotin.

The refined seminar of Chinese University of Science and Technology Yin Xue has found a kind of novel super selenium-enriched plant tall bottle with spout Hairy Bittercress in enshi, the height of its accumulation Se content, the hyperaccumulative plant of two large selenium that can be known with the current world matches in excellence or beauty, the refined seminar of Yin Xue is after carrying out repeatedly scientific investigation to selenium mining area, enshi, the tall bottle with spout Hairy Bittercress found, after drying in its root accumulation selenium up to 8000 micrograms/gram, in leaf accumulation selenium up to 3000 micrograms/gram, can compare favourably with the double hook Radix Astragali and desert Wang Yu.But the selenium of tall bottle with spout Hairy Bittercress accumulation, more than 90% is exist with selenocystine (a kind of special containing selenoaminoacid) form, significantly different from the form of the selenium in the double hook Radix Astragali and desert Wang Yu, probably there is a kind of novel Selenium Metabolism mechanism.

In Blueberry except the sugar of routine, acid and Vc, be rich in the mineral matter elements such as VE, VA, VB, SOD, ursin, protein, anthocyanin, dietary fibre and abundant K, Fe, Zn, Ca.Abundant nutrient component is contained, the nutrition and health care fruit of Gao Xin, high calcium, high ferro, high-copper, homovitamin just because of in Blueberry.It not only has good nutrition health-care functions, also has functions such as preventing cerebral nerve is aging, cardiac stimulant, anticancer softening blood vessel, enhancing human organism immunity.

At present, all adopt the method for foliage-spray inorganic selenium for producing rich selenium blueberry, clearly, first foliage-spray requires that the fertile comparision contents of selenium is high to its shortcoming, and the selenium fertilizer of high concentration adds uses fertile cost; Secondly, because foliage-spray, selenium fertilizer is easy to trickle down to field, so just causes very large waste to field runoff water and soil; Again, often cause inorganic selenium residual quantity large, and inorganic selenium has obvious toxic action to body, safety is lower, can not be used for the production of organic Se-rich agricultural product.

Summary of the invention

The object of the invention is the implantation methods that a kind of organic Se-rich blueberry will be provided.

For achieving the above object, technical scheme of the present invention is:

This implantation methods comprises the steps:

(1) rich selenium organic substrate composition: make after mixing with following material and materials weight part ratio: containing selenium tall bottle with spout Hairy Bittercress 1-3 part, stalk fermentation material 20-40 part, decomposed cow dung 10-30 part, makes through stack retting after mixing;

(2) blueberry thickness of sowing is every square metre of nursery 200 strain, lid seedling medium thickness 0.5 centimetre;

(3) before blueberry is transplanted, first use the rich selenium organic substrate of rich selenium and make base manure, amount of application is every mu of 120-150 kilogram;

(4) use the rich selenium organic substrate of rich selenium as topdressing in blueberry phase of bearing fruit of blooming, amount of application is every mu of 100 ~ 120 kg;

After above-mentioned steps process, after blueberry maturation, namely obtain organic Se-rich blueberry.

As preferably, the described full Se content of tall bottle with spout Hairy Bittercress is greater than 0.3%.

Beneficial effect of the present invention is:

(1) from blueberry seedling breeds, just always for blueberry provides sufficient selenium source, thus make blueberry can absorb in whole vegetative period from soil and be converted into Organic Selenium by photosynthesis, in Blueberry, organic selenium content be high, and stable.

2) method of rich selenium seedling medium and soil application is adopted, plantation organic Se-rich blueberry, change the drawback that rich selenium blueberry is produced in foliar application in the past, and it is fertile no longer to use the inorganic selenium such as selenite, selenate, greatly reduces the environmental pollution that selenium fertilizer may cause.

Embodiment

Below by specific embodiment, technical scheme of the present invention is further described:

Implantation methods comprises the steps:

(1) rich selenium organic substrate composition: make after mixing with following material and materials weight part ratio: containing selenium tall bottle with spout Hairy Bittercress 2 parts, stalk fermentation material 20-40, decomposed cow dung 10-30, makes through stack retting after mixing;

The described full Se content of tall bottle with spout Hairy Bittercress is greater than 0.3%.

The fertilizer that field management is executed is the rich selenium organic substrate of rich selenium:

(1) before blueberry is transplanted, first use the rich selenium organic substrate of rich selenium and make base manure, amount of application is 130 kilograms every mu;

(2) use the rich selenium organic substrate of rich selenium as topdressing in blueberry phase of bearing fruit of blooming, amount of application is 110 kilograms every mu.

Blueberry maturation measures the total selenium content in Blueberry afterwards, the content of Simultaneously test Organic Selenium and inorganic selenium.After testing after blueberry maturation, its pulp selenium content reaches 0.8-0.8mg/kg, average out to 0.85mg/kg, reaches the standard of rich selenium blueberry.Apply the organic selenium content that the present invention effectively can improve Blueberry as can be seen here.

Claims

1. an implantation methods for organic Se-rich blueberry, is characterized in that: this implantation methods comprises the steps:
