Abstract

The utility model provides a degradable paper cup of growing seedlings, it comprises surface coating layer and base member layer bilayer, the base member layer is 100% polylactic acid fibre paper, the coat is the nutrition layer at base member layer surface coating. After making seedling cup, the nutrition layer of surface coating is passed through matrix soil and is given the seedling with the slow release of nutrient, and many pore structure on base member layer have and well preserve moisture and water retention function, in addition, the utility model relates to a seedling cup need not transplant the back seedling of growing seedlings, can directly take the cup to be transplanted to big tanaka together, can effectively protect the seedling root development, promotes the even healthy and strong growth of seedling, carries high viability, and final seedling cup still can degrade green totally.

Description

Degradable nursery dixie cup

Technical field

This utility model is related to agricultural field of new and in particular to a kind of degradable nursery dixie cup, is a kind of can achieve The agricultural papers cup that the crops initial stage is cultivated, can effective protection promote the growth of crops, natural degradation, environmental protection section About.

Background technology

At present, the seedling-raising cup commonly using on the market is a kind of plastic made for base material through molding with pvc, though So can Reusability, but just can be transplanted to big Tanaka, so meeting when needing after seedling culture to take out Seedling from seedling-raising cup A certain degree of damage is caused to seedling root, is unfavorable for the good growth of seedling, and this kind of pvc seedling-raising cup cannot be given birth in seedling The long stage provides nutrition, and seedling growth density cannot preferably be adjusted, and sucting wet air permeability is poor, is easily caused rice shoot root rotten Rotten, and difficulty or ease degraded, while can not reaching fine nursery requirement, because pvc plastics are non-degradable, environment is caused greatly Harm.

Content of the invention

The weak point existing for this area, the purpose of this utility model is to provide a kind of nursery dixie cup, is realizing seedling Seedling is cultivated, and while promoting seedling growth, eliminates the harm to environment, improves rice shoot survival rate.

For solving the above problems, this utility model adopts the following technical scheme that a kind of degradable nursery dixie cup, using bilayer Structure design, including Primary layer, nutritive layer and cup bottom, described nutritive layer is coated on Primary layer inner surface, described Primary layer appearance Face offers more than one aperture, and described Primary layer upper end is also equipped with mark board, and described mark board passes through connecting rod and base This layer is connected, and described cup bottom also offers more than one aperture.

Preferably, described Primary layer is 100% acid fiber by polylactic paper.

Preferably, nutritive layer is covered in described cup primary coat.

The beneficial effects of the utility model are:

1) nexine of the polylactic acid warm nursery paper that this utility model is related to contains nutritive layer, can pass through cup in growth of seedling Nutrition is slowly discharged by interior substrate soil, and meanwhile, the small ventilating holes of a diameter of 0.5-0.8cm are contained in seedling-raising cup bottom, can be to kind The quantity of disseminating of son is adjusted and separates, and is easy to the control that each position seed disseminates quantity, adjusts the stand density of seed, has Help seed uniformly to grow vigorously, improve rice shoot survival rate.

2) because polylactic acid warm nursery paper is loose structure, moisturizing water conservation, institute in hole can be discharged when forgetting and hand over water The moisture keeping, extends the seedling survival time；In addition polylactic acid is a kind of hydrophobic fibre, even if also having good under hygrometric state Intensity, keep the seedling-raising cup shape invariance made, because polylactic acid is a kind of fiber of degradable, can directly by seedling and Seedling-raising cup is transplanted in soil together, slowly degrades with seedling polylactic acid seedling-raising cup of gradually growing up, and ultimately becomes co2 and water, No any pollution to environment.

3) pass through mark board, can facilitate and data acquisition is carried out to nursery.

In sum, this utility model has can provide nutrition, concrete dynamic modulus and water conservation moisturizing to growth of seedling, and can drop Solution, to environment, no any pollution, can effectively improve the survival rate of seedling, thus will have extraordinary application in agriculture field Prospect.

Brief description

Fig. 1 is the surface chart of nursery dixie cup of the present utility model；

Fig. 2 is the structural representation of nursery dixie cup of the present utility model.

Specific embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.

Referring to Fig. 1 and Fig. 2, a kind of degradable nursery dixie cup of the present utility model, using double-decker design, including basic Layer 1, nutritive layer 2 and cup bottom, described nutritive layer 2 is coated on Primary layer 1 inner surface, and described Primary layer 1 outer surface offers one Above aperture 3, described Primary layer 1 upper end is also equipped with mark board 5, and described mark board 5 passes through connecting rod 4 and Primary layer 1 phase Connect, described cup bottom also offers more than one aperture 3, described Primary layer 1 is 100% acid fiber by polylactic paper, described cup bottom Nutritive layer 2 can be coated.

Described nutritive layer 2 thickness is 0.005-0.01mm, and described matrix layer 1 thickness is 0.05-0.22mm, and grammes per square metre is 15- 20g/m2, between 21.6-35.4%, the acid fiber by polylactic length being adopted is 3-5mm to porosity, and fineness is 1-3d.

This degradable nursery dixie cup in the preparation, by non-woven wet-formed method, is initially formed acid fiber by polylactic Warm nursery paper, then in its surface-coated nutritive layer 2, makes the acid fiber by polylactic warm nursery paper containing nutritive layer 2 after drying.

It is 8cm by the seedling-raising cup height that described polylactic acid warm nursery paper is made, cup upper diameter is 7cm, cup lower diameter For 4cm, described seedling-raising cup bottom includes the small ventilating holes of a diameter of 0.5cm in addition, and the inside of seedling-raising cup is containing nutritious Aspect.

The above is only preferred implementation of the present utility model it is noted that common skill for the art For art personnel, on the premise of without departing from this utility model know-why, some improvement can also be made and replace, these change Enter and replace also to should be regarded as protection of the present utility model.
