Abstract

The utility model discloses a ground film, wherein, the middle part of the ground film (1) is provided with a light-reflecting layer (2), while both sides of the ground film (1) are provided with a plurality of soil bags (3). The light-reflecting layer arranged at the middle part of the ground film just covers the ridge where grows asparagus during use to prevent sunlight from directly irradiating newly sprouting asparagus shoot and moisture under the ground film is high, thereby ensuring that asparagus can not form into red head so as to improve product quality; meanwhile, a plurality of soil bags arranged at both sides of the ground film can automatically tension the ground film by means of the soil in the soil bags, thereby making open and close of the ground film very convenient and fast during picking asparagus every day.

Description

Mulch film

Technical field:

The utility model relates to a kind of agricultural mulching, especially a kind of mulch film of producing the white asparagus special use.

Background technology:

In the present spring planting asparagus, for avoiding low temperature effect output and Time To Market, extensively adopt plastic mulching to produce, the employing common ground film covers, if can not in time excavate, after the asparagus point exposes from rib, because solar radiation and water loss, the asparagus point becomes reddish tone, becomes substandard products, has influenced product quality.In addition, because the asparagus growth is rapidly, need repeatedly to excavate in one day, all will raise mulch film at every turn and excavate, covering with plastic film is pushed down the ridging of mulch film both sides then again, repetitive operation, and flip bothers very much, and is time-consuming.

The utility model content:

The purpose of this utility model is to provide a kind of and avoids asparagus to produce reddish tone, flip mulch film easily.

The technical solution adopted in the utility model is, establishes one deck reflector layer on the mulch film middle part, and the mulch film both sides are provided with several native pockets.

As a kind of improvement of the present utility model, native pocket is that this flanging bottom is made as the pocket face with the upwards turnover of dual-side of mulch film, and flanging top inwardly turnover is made as the pocket lid, is provided with some apertures in the pocket relative with the pocket face.

Because the utility model mulch film middle part has increased one deck reflector layer, this reflector layer just in time covers the rib of asparagus growth in the use, has avoided the sunlight direct projection to the asparagus point that just has been unearthed, adds high humidity in the mulch film, guarantee that asparagus can not form reddish tone, improved product quality; Because the mulch film both sides are provided with several native pockets, when using first, epiphragma adds soil on one side in the soil pocket of both sides on one side, utilizes the soil in the native pocket that mulch film is strained automatically, plays the effect windproof, that preserve moisture and heat of fixing, adopting in the bamboo shoot flip process of every day, do not need to add soil again, from a side native pocket is scrolled up together with mulch film when lifting, be placed on above the rib, launch from the top down during lid to get final product, very easy to use quick.

Description of drawings:

Fig. 1 is the utility model structural representation.

Embodiment:

As shown in Figure 1, the utility model mulch film 1 covers on the rib 4 of asparagus growth, has set up one deck reflector layer 2 at mulch film 1 middle part, and this reflector layer 2 can adopt aluminium foil to make, and also can adopt the anti-hot polymeric coating layer of shading, to reduce the irradiation of sunlight.The utility model can adopt the thickening mulch film, and thickness can be about 0.01mm, and intensity is big, and anti-pullling is reusable, is 2-3 service life.For adapting to hot and humid, the not requirement of needs sunlight of asparagus growth, can adopt black mulch film, heat soon temperature in the shed height, high humidity.Mulch film 1 both sides are provided with native pocket 3 in a row, soil pocket 3 can be made earlier independently, side with mulch film 1 is formed by connecting again, also can be to utilize the side turnover of mulch film 1 to form, be about to the upwards turnover of mulch film 1 dual-side, this flanging bottom is the pocket face, and flanging top is reserved several centimeters inside turnovers of continuation and made pocket lid 31, and pocket lid 31 can prevent that the soil in the pocket leaks outside when adopting bamboo shoot flip mulch film 1.The inboard mulch film of the not turnover relative with the pocket face forms in the pocket, can have a plurality of apertures in the pocket, discharges the rainwater in the pocket when being used for raining.Be a succession of little native pocket 3 that formation is separated by, link to each other at a certain distance in pocket face and the pocket that being connected in pocket face and the pocket can be adopted heat pressing process, also can adopt bonding mode.The size of each native pocket 3 will suit, soil pocket 3 is excessive, and the ease of connection in pocket face and the pocket is thrown off, the flip effort, soil pocket 3 is too small, not having windproof fixing effect, is that 1 meter mulch film is an example with width, and it is 1/3rd wide that reflector layer 2 accounts for, the mulch film 1 of rib 4 both sides respectively accounts for 1/3rd, each native pocket 3 is wide 10 centimeters, and high 5-6 centimetre, pocket cover 31 high 2-3 centimetres.Liftoff 2-3 centimetre was answered at 3 ends of native pocket after mulch film 1 covered, and could utilize native pocket 3 to make mulch film 1 tensioning like this.

Claims

1, a kind of mulch film is characterized in that: mulch film (1) is established one deck reflector layer (2) on the middle part, and mulch film (1) both sides are provided with several native pockets (3).

2, mulch film according to claim 1, it is characterized in that: described native pocket (3) is such, and mulch film (1) dual-side is turnover upwards, and this flanging bottom is made as the pocket face, flanging top inwardly turnover is made as pocket lid (31), is provided with some apertures in the pocket relative with the pocket face.
