Abstract

The rhizome of a yam can reach one meter under the ground, and the texture is crisp and tender. Thus, when yams are dig, a lot of labor and time are taken, and the yams are easy to damage. The present invention provides a hole type yam cultivation method which comprises the following steps: drilling vertically in the field by the special punch; closing a mulching film, and seeding yams in the mulching film at the hole opening. Thus, after passing through the mulching film, the yams can freely grow under a hanging status so as to greatly enhance the quality of the yams. The yams are easy to collect and the damage to the yams when the yams are collected and dig is completely avoided.

Description

Hole type yam cultivation method

One, technical field

The present invention relates to the yam cultivation technology, particularly relate to a kind ofly, again Chinese yam is planted the technology on the hole in the vertical perforate of Tanaka.

Two, background technology

Because the rhizome of the Chinese yam length under in depth can reach 1m, Chinese yam rhizome quality is tender and crisp in addition, so very time-consuming when gathering.For this reason, the applicant is 2003101041049 " Chinese yam easily overturn glass steel tank cultivation " in the application number of on December 24th, 2003 application, this application has solved the difficult problem of gathering of Chinese yam, but must invest the glass steel tank, be not suitable for simultaneously the land for growing field crops produces very much, the application number of on May 23rd, 2005 application is the investment that " method for culturing Chinese yam of filling polystyrene partical in narrow-space " this application of 2005100209357 has been saved the glass steel tank, and be suitable for the land for growing field crops and produce, but for trench digging still need drop into more man-hour, also has the investment of foamed polystyrene grain and film simultaneously before the plantation.

Three, summary of the invention

The purpose of this invention is to provide a kind of hole type yam cultivation method, the labor inputs that makes cultivation and results still less, and better effects if.

The object of the present invention is achieved like this: the Tanaka who intends kind of Chinese yam, dig the thick soil layer of table 15～18cm of turning up the soil by row earlier, punch straight down by predetermined spacing in the rows with special-purpose field soil card punch again, aperture 10cm, hole depth 1.3m, after extracting card punch out, inserting a thickness in the aperture is the polypropylene light wall pipe of 1mm, and the external diameter of light wall pipe is consistent with the diameter in hole, this place, and length is 30cm, the bottom of pipe is straight tube, upper port is along there being a transverse annular fin, and the overall diameter of annular flap is 15cm, thickness 1mm, upper flap lastblock thickness 0.02mm at light wall pipe, diameter is the polyethylene film of 25cm, with film along the peripheral reflexed of light wall pipe ring-type fin suitable for reading and be pressed on fin and soil between, in the centre of film with the openning of blade standardized road length 3cm, again Chinese yam kind piece is put in the center and the blinding of the film of light wall pipe mouth, allow kind of bud of piece upwards during blinding, during results, dig and open soil layer, hold Chinese yam reed head, Chinese yam is proposed to get final product in the hole.Special-purpose field soil card punch main body is the steel cylinder, the length of cylinder is 1.3m, internal diameter is 9cm, external diameter is 10cm, it is identical with it that the lower end of cylinder connects one section external diameter by stationary fit, length is 15cm, material is the taper hole head of carbide alloy, the end opening of its endoporus becomes the big down little tubaeform taper hole of, the tapering of taper hole is 20 °, the height of taper hole is 10cm, the back cut diameter in hole is 8.5cm, the length of fit of taper hole head and cylinder is 3cm, it is 9.5cm that there is one section long external diameter of 5cm on the top of cylinder apart from port, is covering a lid on this cylindrical section, and the internal diameter of lid is 9.6cm, external diameter is 11cm, the length of lid is 7cm, and the interior hole depth of lid is 5.5cm, and the top of cylinder has the through hole of two aperture 0.82cm along diameter apart from port 3cm place, so that before transfering to card punch, connect drop handle, drop handle is long by one section 50cm, the steel bar of diameter 0.8cm bends to Ω shape, and during punching, hammering is covering, after reaching desired depth, throw off lid, connect drop handle, the rod with long a 2.5～3m penetrates drop handle again, with lever principle card punch is extracted, and soil is wherein outwelled.

Adopt such scheme can receive following remarkable result:

1, because the rhizome of Chinese yam is freely grown with regard to being under the vacant state fully after passing through mulch film, and Shou Huo Chinese yam can be realized the optimal bodily form and the most smooth appearance like this, its commodity value is inevitable to be improved greatly.

2, because the Chinese yam rhizome is in vacant state, to take out gently and get final product so need only hold the reed head when gathering, not only laborsaving saving time also can be avoided the damage of Chinese yam fully.

3, the cultivation of Chinese yam investment more economizes, and makes a call to a hole and can use for many years repeatedly.

4, because the taper hole head of card punch bottom becomes big down little tubaeformly, what this had not only helped card punch deeply but also very is convenient to extract native bar in the card punch hypsokinesis rewinding.

During 5, owing to punching is the loam cake that impacts, so can not injure the suitable for reading of card punch, this just is unlikely to influence native toppling in the tube.

6, owing to insert the polypropylene light wall pipe of one section band shape fin, and be equipped with mulch film, can prevent from effectively that earth around the aperture from collapsing to fall within the hole at the ground orifice part.

Five, embodiment

The Tanaka who intends kind of Chinese yam, dig the thick soil layer of table 15～18cm of turning up the soil by row earlier, punch straight down by predetermined spacing in the rows with special-purpose field soil card punch again, aperture 10cm, hole depth 1.3m, after extracting card punch out, inserting a thickness in the aperture is the polypropylene light wall pipe of 1mm, and the external diameter of light wall pipe is consistent with the diameter in hole, this place, and length is 30cm, the bottom of pipe is straight tube, upper port is along there being a transverse annular fin, and the overall diameter of annular flap is 15cm, thickness 1mm, upper flap lastblock thickness 0.02mm at light wall pipe, diameter is the polyethylene film of 25cm, with film along the peripheral reflexed of light wall pipe ring-type fin suitable for reading and be pressed on fin and soil between, in the centre of film with the openning of blade standardized road length 3cm, again Chinese yam kind piece is put in the center and the blinding of the film of light wall pipe mouth, allow kind of bud of piece upwards during blinding, during results, dig and open soil layer, hold Chinese yam reed head, Chinese yam is proposed to get final product in the hole.
