Abstract
The utility model relates to an agricultural plastic mulching film, in particular to an automatic seedling-placing mulching film. The automatic seedling-placing mulching film comprises a common plastic mulching film for agriculture and an oxidation-biological dual-degradation strip-shaped plastic film, which are equal in length, wherein the common plastic mulching film has seedling outlets, and the oxidation-biological dual-degradation strip-shaped plastic film is arranged on the seedling outlets. By the automatic seedling-placing mulching film, the problems that the seedling placing is labor-consuming and time-consuming, and seedlings are easy to damage are solved; the automatic seedling-placing mulching film has the characteristics of simple structure and convenience in production; and after the seedlings come out, the hole-sealing film can be automatically degraded, degradation products can be absorbed by soil, and pollution is avoided.
Description
Technical field
The utility model relates to a kind of agricultural mulching, is specifically related to a kind of mulch film insulation soil moisture conservation function that both had, and has again the automatic releasing seedling, does not burn the mulch film of seedling effect.
Background technology
The mulch film that uses at present mostly is greatly the sealing mulch film, has well to heat the soil moisture conservation function, but needs the cost manpower put seedling, if put the untimely phenomenon such as seedling burn that also easily causes of seedling.
Recorded and narrated the protectiveness coverlay of a Plants among the Chinese patent CN2209438Y; its feature is to establish the hole of emerging at regular intervals on the basis of existing mulch film; the hole of emerging is provided with the sealing of hole film that can tear off, only need tear the sealing of hole film when putting seedling, delegation's seedling can be emitted.But this design has certain defective, and common ground film itself tears and damages easily mulch film in the process of sealing of hole film, and need the secondary manual operation when emerging because thickness is very little, so limited by practical.
Oxidation-biodegradation plastic is that a kind of the plasticizing by common non-degradative plastics base material (such as PE) with after the two degradant additives of nano-high molecule multi-component compound evenly mix on a small quantity processes, have the degradative plastics of catalyzing oxidizing degrading and biodegradation character concurrently, its physical property (mechanics, the transparency, texture etc.) is suitable with the common plastics of identical material, specification.Catalysed oxidn by degradant additive can make the molecular weight of common polyolefin plastics be reduced to below 10000 from initial tens0000 even hundreds of thousands.The plastics chain rupture that molecular weight arrives this level contains the hydrophilic radicals such as abundant carboxyl, carbonyl, can progressively be degraded by microorganism, and end product is water, carbonic acid gas and humus.Oxidation-biodegradation plastic has begun to be widely used in every field by people at present.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of no seedling injury, need not the mulch film of artificial seedling setting.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of automatic releasing seedling mulch film comprises mulch film, emerge hole and sealing of hole film, and the hole of emerging is equally spaced to be arranged on the mulch film, and the sealing of hole film fixedly is attached on the hole of emerging and is connected with mulch film, can not remove; The sealing of hole film adopts degradation material to make.
As preferably, described sealing of hole film adopts oxidation-biodegradation plastic to make.
The beneficial effects of the utility model are: the utility model is simple in structure, is convenient to produce, and has kept the original insulation soil moisture conservation of mulch film function, solved simultaneously that to put seedling time-consuming, the problem of easy damaged seedling, and the catabolite of sealing of hole film can be absorbed by crops, do not pollute.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model is put seedling structural representation afterwards;
Wherein, 1. mulch film, the hole of 2. emerging, 3. sealing of hole film.
Embodiment:
As shown in Figure 1, automatic releasing seedling mulch film of the present utility model, comprise mulch film 1, be provided with the hole 2 of emerging at mulch film 1, hole 2 is bonded with sealing of hole film 3 emerging, sealing of hole film 3 mainly is comprised of polyethylene (PE) and a small amount of oxidation-bio-degradable catalyzer, and the degradation time of sealing of hole film can be controlled by the content of catalyzer.
As shown in Figure 2, after the seedling of crop grew, in good time degraded had occured in sealing of hole film 3, exposed the hole 2 of emerging, thereby did not affect the growth of crop seedling.
More than the utility model embodiment is described in detail, used embodiment herein the utility model set forth, the explanation of above embodiment just is used for helping to understand product of the present utility model; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
