The planting unit of a kind of rich selenium leek and method
Technical field
The present invention relates to field of agricultural cultivation, relate to a kind of planting unit and the method that use rich selenium leek specifically.
Background technology
Selenium is a kind of required trace element of a kind of humans and animals, have scavenging free radicals anti-oxidant, delay senility, anticancer, the biological property such as develop immunitypty, antagonism heavy metal.The data that WHO announces also shows, the whole world has more than 40 country to belong to low selenium or scarce selenium area.Human body selenium source is main, and by dietary int ake, rich selenium agricultural byproducts are human body Selenium Supplement element effective ways, and therefore, technique of enriched selenium is the hot fields of scientists study exploitation.The Se content of crops is generally by the impact of crop varieties, Selenium in Soil content and the factor such as some physical and chemical indexs, agronomy control measures.China belongs to the country that soil seriously lacks selenium, and the whole nation about has the area of 70% all to belong to scarce selenium area.The selenium deficiency of soil directly results in the deficiency of Se content in most of regional crops, makes China a big chunk crowd be in selemium nutrition deficiency state.
At present in the field of planting of selenium-enriched crop, common method has: 1) by spraying Selenium-rich nutrient solution on the blade face or limb of crop or fruit tree.2) or nutrient solution fertile by the rich selenium of injection in limb.3) by applying rich selenium fertilizer or solid-state selenium in the soil of crop root.But said method exists, and operation is loaded down with trivial details, the amount of labour large, low to the availability of selenium, the shortcomings such as loss is large.Therefore a kind of selenium-rich crops implantation methods that can overcome above-mentioned defect is needed badly.
Summary of the invention
The object of this invention is to provide the planting unit in a kind of efficient selenium-rich crops plantation, and utilize this device to the method for carrying out the plantation of rich selenium leek.
The planting unit realizing a kind of rich selenium leek of above-mentioned purpose of the present invention comprises:
The planting unit of a kind of rich selenium leek: comprise kettle body 1, described kettle body 1 has the structure of hollow to store Selenium-rich nutrient solution, opening is arranged at the top of kettle body 1, position corresponding to kettle body 1 opening is fixed with location division 2, described location division 2 has internal thread, filling mechanism, this filling mechanism comprises funnel-shaped upper part 3 and tubular lower 4, described funnel-shaped upper part 3 and the junction of tubular lower 4 are provided with spring cup 5, described tubular lower 4 is provided with the external screw thread adapted with location division, this location division 2 can be threaded connection and screw in kettle body 1 inside, the height that described filling mechanism exposes kettle body 1 can be regulated by this screw thread rotation, the side of described kettle body 1 is provided with mechanism for filling liquid, described mechanism for filling liquid comprises tubular rear 9 and open shape front portion 10, described open shape front portion 10 is provided with multiple liquid injection hole, the top of described tubular rear 9 and anterior 10 junctions of open shape is provided with opening, lifting rod inserts in mechanism for filling liquid by this opening, lifting rod comprises the handle 6 on top, the bar 7 at middle part and the limiting plate 8 of bottom, the folding of mechanism for filling liquid is realized by this lifting rod, stopping means prevents this lifting rod pull-out mechanism for filling liquid.
Preferably, described mechanism for filling liquid is multiple.
A kind of implantation methods utilizing the planting unit of this rich selenium leek to carry out rich selenium leek, method of operating is: imbedded by this planting unit in the soil near leek root, the open shape front portion of mechanism for filling liquid is made to aim at root, rotating screw thread, to make filling mechanism expose the height of kettle body suitable, put down lifting rod, by liquid feeding structure, Selenium-rich nutrient solution is added in kettle body, spring cup is buckled after adding, to prevent volatilization, during use, mention lifting rod, Selenium-rich nutrient solution is made to flow into the open shape front portion of mechanism for filling liquid, and infiltrate in the soil near root by multiple liquid injection hole, when not needing to use, put down lifting rod,
The step that leek is specifically planted comprises:
(1) select suitable soil as planting site, apply fertilizer, deep plough subsequently, flatten, reserve appropriate rows apart from width to imbed described planting unit, and do ditch furrow with the spacing in the rows of rational close planting;
(2) fresh Allium tuberasum.seeds is selected to carry out vernalization;
(3) Allium tuberasum.seeds of step (2) through vernalization process is sowed in the ditch furrow described in step (1), cover fine earth, and add a cover film, the ratio of 1: 10 is by after Selenium-rich nutrient solution and water mixed dissolution by weight, add described planting unit and apply Selenium-rich nutrient solution to soil, applied amount is 10 kgs/acre;
(4) when the leek rate of coming up after planting reaches about 80%, described film is taken off;
(5) when leek seedling grows to height of seedling about 10 centimetres, carry out Rational Irrigation, apply fertilizer 3-4 kg/acre, Selenium-rich nutrient solution 3-4 kg/acre;
(6) during leek Seedling Height about 15 centimetres, field planting process is carried out to it;
(7) harvesting after maturation of planting seedlings, retaining the above length of root is planting seedlings in order to next batch of growth of 2 ~ 3cm.
Described selenium-rich nutritive fluid component is: sodium selenite 4-6 part, potassium borohydride 2-3 part, boric acid 6-7 part, ammonium molybdate 4-5 part, manganese sulphate 6-8 part, iron ammonium sulfate 9-10 part, wheat bran 1-3 part, magnesium sulfate 2-5 part, urea 10-25 part, 100 parts, water.
Relative to prior art, Advantageous Effects of the present invention is:
1. the availability of pair selenium is high, applies object for the strongest root of Crop ability, improves absorption ratio.
2. easy to use, open spring cup and namely can add or change Selenium-rich nutrient solution, buckle spring cup and nutrient solution can be avoided to volatilize.
3. precision controls, and when needing to use, as long as mention lifting rod just can apply Selenium-rich nutrient solution, when not needing to use, puts down lifting rod, avoids waste.Make the amount of applying selenium realize Precise control, it also avoid excessively applying selenium simultaneously and crop is caused damage.
4. reduce the amount of labour, only need be buried in the earth disposable for this device, can realize repeatedly planting, gather in the crops process continue add selenium.
5. by rational nutrient solution prescription, and applied amount, make the leek obtained both be rich in selenium element, turn avoid and excessively apply to cause damage to soil.
