Description

Double-layer degradable seedling raising bag

Technical Field

The utility model belongs to educate the seedling bag field, concretely relates to double-deck degradable seedling bag that educates.

Background

The seedling raising bag is mainly used for filling prepared matrix or nutrient soil, the seedlings are quickly cultured in a greenhouse, and the cultured seedlings are finally separated from the seedling raising bag and transplanted to other places suitable for growth. The existing seedling raising bag is made of polyethylene films, non-woven fabrics and the like, and is non-degradable and easy to cause white pollution; the root system of the plant can not penetrate through the seedling raising bag, and the root rolling of the pit root can easily occur to influence the growth; the seedling raising bags need to be manually removed in the transplanting process, so that the defects of manual labor increase and the like are overcome.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an it is not enough that one of the purposes lies in overcoming prior art, provides a double-deck degradable seedling bag of growing seedlings, through adopting biodegradable material preparation, has chemical fertilizer slowly-releasing and expelling parasite anti-insect difunctional, and the seedling bag of growing seedlings of preparation does not need the manual work to get rid of the seedling bag in the nursery stock transplanting process, effectively saves the labour.

The utility model adopts the technical scheme as follows:

the utility model provides a double-deck degradable seedling raising bag, includes the seedling raising bag body, the seedling raising bag body adopts double-deck solvability environmental protection material to tailor folding formation, and seedling raising bag body upper end is the open end, and there is the side crease in the centre of seedling raising bag body both sides, and the folding of seedling raising bag both sides of formation along the relative folding formation of side crease has the crease in the centre of seedling raising bag body bottom, and the folding condition of seedling raising bag is accomplished along the folding of crease infolding in seedling raising bag body bottom to the bottom of seedling raising bag body bottom, the seedling raising bag body includes slowly-releasing layer and insect-resistant layer, the slowly-releasing layer is starch/PBAT composite fertilizer slowly-releasing layer, the insect-resistant layer is the stiff insect-resistant layer of PBAT.

Furthermore, the lateral wall and the bottom of the seedling bag body are provided with air holes.

Compared with the prior art, the utility model has the advantages of it is following:

the utility model provides a double-deck degradable seedling raising bag adopts biodegradable materials to prepare, and is degradable, has the characteristics of environmental protection, through adopting the hard very insect-resistant layer of PBAT that PBAT, inorganic granule, insect repellant, insecticide compound preparation formed, realizes the function of expelling parasite insect, through setting up starch/PBAT compound fertilizer slow-release layer, realizes the function of fertilizer slowly-releasing; meanwhile, the seedlings can be directly buried in the soil in cooperation with the seedling raising bags, the root growth cannot be influenced, and a large amount of labor cost is reduced.

Drawings

FIG. 1 is a schematic use view of the double-layer degradable seedling-raising bag of the utility model;

FIG. 2 is a schematic structural view of a seedling raising bag body.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and features in the embodiments and embodiments in the present application can be combined with each other without conflict.

As shown in fig. 1, fig. 2, a double-deck degradable seedling bag that educates, including educating seedling bag body 1, educate seedling bag body 1 and adopt double-deck solvability environmental protection material to tailor folding formation, educate seedling bag body 1 upper end and be open end 11, there is side crease 12 in the centre of educating seedling bag body 1 both sides, educate seedling bag body 1 both sides along the folding formation of the relative side crease 12 of educating seedling bag both sides, there is the crease in the centre of educating seedling bag body 1 bottom, educate seedling bag body 1 bottom along the folding formation of the inside folding formation of crease educating seedling bag bottom, the fold condition of seedling bag is accomplished in the folding of side and bottom, bleeder vent 13 has all been seted up to the lateral wall and the bottom of educating seedling bag body 1.

The nursery sock growing bag body 1 comprises a slow release layer 2 and an insect-resistant layer 3, the slow release layer 2 is a starch/PBAT composite fertilizer slow release layer, the insect-resistant layer is a PBAT stiff insect-resistant layer 3, the PBAT is poly adipic acid/butylene terephthalate, the slow release layer has good toughness, is easy to form a film and can be completely degraded, the starch/PBAT composite fertilizer slow release layer is arranged on the inner side of the nursery sock growing bag, in the preparation process of the starch/PBAT composite material, urea is used as one of plasticizers, when the nursery sock growing bag is used, in the gradual degradation process of the starch/PBAT composite layer, the urea slowly migrates into soil to fertilize nursery stocks, the starch and the PBAT carry out composite acceleration of degradation rate, the PBAT stiff insect-resistant layer is arranged on the outer side of the starch/PBAT composite layer, the PBAT stiff insect-resistant layer is prepared by compounding PBAT, inorganic particles, insect repellents and pesticides, and the degradation rate of the layer is lower than that of the starch/PBAT composite fertilizer slow release layer, the fertilizer can be prevented from being diffused to the external soil, and the utilization rate of the fertilizer is improved; the starch/PBAT composite fertilizer slow-release layer is added with an insect repellent insecticide, so that the root of the seedling can be effectively prevented from being affected by insect pests; inorganic particles such as talcum powder and the like are added to increase the stiffness of the film, so that the matrix or the nutrient soil is added conveniently in the using process.

The utility model adopts biodegradable composite material preparation, is degradable, has the characteristic of environmental friendliness, realizes the functions of expelling insects and resisting insects by adopting the PBAT stiff and insect-resisting layer which is prepared by compounding PBAT, inorganic particles, insect repellant and insecticide, and realizes the function of slowly releasing fertilizer by arranging the starch/PBAT compound fertilizer slow-release layer; meanwhile, the seedlings can be directly buried in the soil in cooperation with the seedling raising bags, the root growth cannot be influenced, and a large amount of labor cost is reduced.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all utilize the equivalent structure or equivalent flow transformation that the content of the specification does, or directly or indirectly use in other related technical fields, all including in the same way the patent protection scope of the present invention.
