Abstract
The invention discloses a selenium-rich eggplant planting method, wherein a stem of a same fruit is applied with selenium solutions of different concentrations for twice, at the enlarging period of the eggplant fruit, the stem is applied with a sodium selenite aqueous solution whose concentration is 100-120mg/kg when the eggplant fruit grows to 3-4cm, the stem is applied with a sodium selenite solution whose concentration is 200-250mg/kg 7-10 days after the first applying of the selenium solution, the applying starts from the joint of the stem and a bearing branch to a sepal of the fruit, and the whole stem is applied during applying. By applying the selenium product on the stem, inorganic selenium is absorbed and transformed into organic selenium and is enriched in the fruit, the content of the organic selenium in the eggplant fruit is increased, and the detection shows that the content of the organic selenium is more than 20ug/kg. By applying the selenium product on the stem and directionally guide the selenium to produce the selenium-rich eggplant, the variable is accurately targeted, the selenium element is applied, the method is more targeted, the selenium enrichment effect is better, the amount of inorganic selenium used is reduced, and the negative influence to the environment is reduced.
Description
Technical field
The present invention relates to a kind of eggplant implantation methods, especially a kind of eggplant implantation methods that is rich in trace elements of selenium, belongs to agricultural planting technique field.
Background technology
Selenium is the important trace element of needed by human, and preventing disease theraping effect is obvious, and health is had to very important meaning.The not only high 10-20% of the more common eggplant of nutritious, selling price of rich selenium eggplant.Selenium can improve human immunity, promotes the synthetic of lymphocytic propagation and antibody and immunoglobulin, and medical care effect is obvious, favored by consumer, and supply falls short of demand in market.Therefore, producing rich selenium eggplant is that vegetable grower increases income and the Important Action of residents' interest insurance.
At present, rely on soil to enrich or the absorption of the fertile promotion of crop foliage-spray selenium eggplant to selenium, to producing rich selenium eggplant.This is a rich selenium approach of effective eggplant really, but also has the not drawback such as easy-regulating and the negatively influencing to environment of selenium level in product.Negatively influencing to environment is mainly manifested in: in rich selenium process, ignore target information, apply selenium-enriched fertilizer selenium element is implanted in plant corpus from root, leaf portion, make a large amount of selenium elements apply the problem of environmental pollution causing in non-target environment.
Summary of the invention
The problem to be solved in the present invention is the deficiency overcoming in background technology, a kind of implantation methods of rich selenium eggplant is provided, smear rich selenium product by carpopodium, inorganic selenium being sucked and is converted into Organic Selenium is enriched in fruit, improve the organic selenium content in eggplant fruit, thereby improve quality and the added value of eggplant product.
For addressing the above problem, the present invention takes following technical scheme: a kind of implantation methods of rich selenium eggplant, is characterized in that: in eggplant fruit expanding period, successively smear the carpopodium of same fruit with the selenium liquid of variable concentrations 2 times.
A kind of prioritization scheme, smears selenium liquid: when eggplant fruit grows to 3-4cm, smear carpopodium with the sodium selenite aqueous solution that concentration is 100-120mg/kg for the first time.
Further, smear for the second time selenium liquid: smear for the first time 7-10 days after selenium liquid, smear this carpopodium with the sodium selenite aqueous solution of 200-250mg/kg.
Further, described sodium selenite aqueous solution contains organosilicon auxiliary agent.
Further, described organosilicon auxiliary agent is ethyoxyl modification trisiloxanes.
Further, the concentration of described ethyoxyl modification trisiloxanes is 100-120mg/kg.
Further, while smearing, start to smear to the sepal direction of fruit from carpopodium and fruit bearing shoot junction.
Further, while smearing, smear whole carpopodium.
Smear the method for carpopodium, start to smear to the sepal direction of fruit from carpopodium and fruit bearing shoot junction, smear length and determine according to the length of carpopodium, conventionally smear whole carpopodium.
The carpopodium of whole fruits that stay all will be smeared sodium selenite aqueous solution 2 times, smears successively by the sequencing of bearing fruit, and can not leak and smear.
When preparation sodium selenite aqueous solution, should be mixed with organosilicon auxiliary agent, to increase solution divergence and adhesive force, extend the holdup time of selenium solution on carpopodium, put forward selenium-enriched effect.
Adopt above technical scheme, compared with prior art, have the following advantages:
1) in eggplant fruit development process, smear rich selenium product by carpopodium, inorganic selenium is sucked and is converted into Organic Selenium and be enriched in fruit, improve the organic selenium content in eggplant fruit, after testing, organic selenium content is greater than 20 μ g/kg.
2) produce rich selenium eggplant by smearing directed importing of carpopodium, realized target precision variable and applied selenium element, Objective is stronger, rich selenium better effects if.
3) reduce the usage amount of inorganic selenium, reduced the negatively influencing to environment.
Below in conjunction with specific embodiment, the invention will be further described.
