A kind of planting unit of selenium-rich millet 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 selenium-rich millet 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 selenium-rich millet plantation.
The planting unit realizing a kind of selenium-rich millet of above-mentioned purpose of the present invention comprises:
A kind of planting unit of selenium-rich millet: 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, described liquid injection hole is circular, 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 selenium-rich millet to carry out selenium-rich millet, it is characterized in that: this selenium bringing device is imbedded in the soil near paddy shoot root portion, the open shape anterior 10 of mechanism for filling liquid is made to aim at root, rotating screw thread, to make filling mechanism expose the height of kettle body 1 suitable, put down lifting rod, by liquid feeding structure, Selenium-rich nutrient solution is added in kettle body 1, spring cup 5 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 10 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 millet is specifically planted comprises:
1) selection of land, select soil layer thick, soft, have the soil of good irrigation conditions as millet planting site;
(2) apply fertilizer, after upper one batch of crop harvesting, remove stalk weeds, kill disease worm, deep plough one time, apply fertilizer subsequently, plough shallowly one time, leveling;
(3) choose seeds, select the millet of high-quality to plant, and dibbling after ditching to the soil having executed fertilizer, sowing earthing, and imbed described planting unit at correct position;
(4) irrigate at Germination period, after having gone out seedling, apply fertilizer by the amount of 30 kgs/acre, and by weight the ratio of 1: 10 by after Selenium-rich nutrient solution and water mixed dissolution, add described planting unit and apply Selenium-rich nutrient solution to soil, applied amount is 10 kgs/acre;
(5) field nursing, comprise loosen the soil, thinning, weeding;
Described selenium-rich nutritive fluid component is: sodium selenite 4-6 part, potassium borohydride 1-2 part, boric acid 4-5 part, ammonium molybdate 2-3 part, manganese sulphate 1-2 part, iron ammonium sulfate 7-8 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 millet obtained both be rich in selenium element, turn avoid excessively applying selenium and soil is caused damage.
