Description

A kind of the radix tetrastigme culture apparatus and its design method of anti-weeds
Technical field
The present invention relates to the artificial growth fields of radix tetrastigme, a kind of radix tetrastigme culture apparatus more particularly to anti-weeds and Its design method.
Background technique
Radix tetrastigme is Vitaceae Tetrastigma plant, scientific name tetratigma hemsleyanum (Tetrastigma hemsleyanum Diels et Gilg) also known as gold thread hoist.Radix tetrastigme is a kind of rare vegetable drug in China, and herb can be used as medicine, with ground The medicinal effects of lower root tuber and fruit are best, and whole year can be harvested, and dry or using fresh herb.Its mild-natured, mildly bitter flavor has clear Thermal detoxification, dispelling pathogenic wind and eliminating phlegm, promoting blood circulation and stopping pain and other effects cure mainly venomous snake bite, tonsillitis, scrofula, traumatic injury, children The diseases such as hyperpyretic convulsion.Modern medicine discovery, radix tetrastigme can also be used to treat viral meningitis, the acute friendship tracheae for the treatment of The infectious diseases such as inflammation, pneumonia, sphagitis, enteritis, infection of biliary tract and eye danger cellulitis, or even prevention and treating cancer.Mesh Preceding radix tetrastigme product available on the market, is all to use wild kind for raw medicinal material mostly, therefore, is gone out in Chinese Medicinal Materials Markets Situation that now supply falls short of demand.
Someone started to carry out the trial of radix tetrastigme artificial growth in recent years, mainly used the cuttage plantation of greenhouse field and hayashishita basin Plant, applied for several patents of invention, such as Jiang Weimei invented quick breeding by group culture radix tetrastigme technology (application number: 200710070701.2), (application number: 201210562509.6), Pu is bright and beautiful for the method for the inventions such as Hu Xinyin potted plant growth radix tetrastigme Treasured is equal, it is auspicious it is brave etc. then propose field cultivation radix tetrastigme method (application number: 201210252098.0,201210426679.1), Pan great Ren etc. propose with building the arbors mixed forest such as cypress, pine and cypress and camphor tree potting interplanting method (application number: 201410027914.7)。
But during current radix tetrastigme artificial growth, weeds easy to breed, it usually needs every 2-3 months are artificial Weeding is primary.To avoid pollution by pesticides and influencing the pharmacological property of radix tetrastigme, removes weeds and be forbidden to use chemical herbicide.If using Pure manual uprooting weed mode weeding, then it is time-consuming and laborious, need a large amount of labours.
Summary of the invention
To solve the problems, such as weeds propagation and widespread during radix tetrastigme artificial growth, the present invention proposes a kind of radix tetrastigme of anti-weeds Culture apparatus and its design method, culture apparatus of the invention have anti-weeds film, utilize culture apparatus of the invention, Ke Yi The growth that weeds are reduced under the premise of without using chemical herbicide advantageously reduces labour's investment.
To achieve the above object, the present invention proposes a kind of radix tetrastigme culture apparatus of anti-weeds, including anti-weeds film, nursery Bag and cultivating container, Seedling bag are bonded together with round plastic film, in the hole of Seedling bag insertion cultivating container, and by anti-weeds Film is covered on cultivating container.
Wherein, anti-weeds film is with a thickness of 8, the circular black anti-aging plastic film that diameter is 42 centimetres, entire plastics Film is split trisection, and in the intermediate aperture of each section of trisection, the diameter in hole is 3 centimetres, and the center in hole is to round The distance at the center of plastic foil is 8 centimetres;The circumferential edges of anti-weeds film are equably provided with 6 insertion points, insert in insertion point Enter fixing card, fixing card is the cylindric bamboo stick that 10 centimetres long, diameter is 0.5 centimetre or 10 centimetres long, side length is 0.5 centimetre Square column bamboo stick;
Seedling bag be diameter be 3 centimetres, high 5 centimetres of the degradable Seedling bag of cylinder, the diameter of Seedling bag and anti-weeds The diameter in the hole on film is identical, and upper and lower ends are not closed openings, by the hole on the round bottom edge of Seedling bag and anti-weeds film Seedling bag and anti-weeds film, are bonded together by alignment using hot pressing mode;
Cultivating container be diameter be 35 centimetres, high 35 centimetres of bulge, material be non-woven fabrics or PVC plastic film, The cultivation matrix configured as required is filled up in cultivating container, is opened up on the upper surface of cultivating container there are three hole, the diameter in hole It is 3.5 centimetres, hole gos deep into 5 centimetres of matrix, and the position in hole is corresponding with the position in hole on anti-weeds film.
The present invention also proposes a kind of design method of the radix tetrastigme culture apparatus of anti-weeds, comprising the following steps:
S1 chooses the black anti-aging plastic film with a thickness of 8, plastic foil is cut into 42 centimetres of diameter of round plastic Circular plastic foil is divided equally into trisection using polygometry by film;
S2, in the intermediate aperture of each section of trisection, the diameter in hole is 3 centimetres, and the center in hole is into plastic foil The distance of the heart is 8 centimetres;
S3 chooses 3 centimetres of diameter, 5 centimetres high, the not closed degradable Seedling bag of cylinder of upper and lower ends, by Seedling bag Round bottom edge be aligned with the hole on plastic foil, Seedling bag and plastic foil are bonded together using thermal pressure;
S4 designs fixing card, by long 10 centimetres, diameter be 0.5 centimetre cylindric bamboo stick or 10 centimetres long, side length be 0.5 centimetre of square column bamboo stick will be consolidated as fixing card in 6 insertion points of circumferential edges uniform design of round plastic film Determine the insertion point that card insertion enters plastic foil;
S5 chooses 35 centimetres of diameter, and the cultivation matrix configured as required is filled cultivation by high 35 centimetres of round cultivating container Then culture container makes a call to three holes with punch in the upper surface of cultivating container, the diameter in hole is 3.5 centimetres, and hole gos deep into 5 lis of matrix Rice, the position in hole is corresponding with the position in the hole on plastic foil, by the hole of Seedling bag insertion cultivating container, and by anti-weeds film It is covered on cultivating container, fixed anti-weeds film;
Radix tetrastigme bare-root seeding or Plug seedling are directly placed into Seedling bag, are filled out with cultivation matrix when planting radix tetrastigme by S6 Pressurising is real, watering.
The present invention can reduce the growth of weeds under the premise of not using chemical herbicide, advantageously reduce labour's throwing Enter, and is easily achieved, it is easy to operate, it is low in cost.
By referring to the following drawings and to the detailed description of a specific embodiment of the invention, feature and advantage of the invention It will become apparent.
