Abstract
The utility model relates to a non-woven fabric mulching film composite covering, which comprises non-woven fabric and mulch films, wherein, a fixing film layer and a a movable film layer are arranged between the non-woven cloth and the mulch films; the arrangement of the fixing film layer and the movable film layer can solve the problems of low temperature and small seedling in the early period of non-woven fabric seedling, and over small and irregular seedling on a bedside of non-woven cloth seedling. Besides, the utility model can solve the technical problems of work force of ventilation seedling saving of non-woven fabric seedling.
Description
The utility model relates to agricultural compound quilt, refer to especially a kind of when being applicable to seedling cultivation of rice, the compound quilt of nonwoven mulch film that on its frame, uses.
The main method of seedling cultivation of rice is at present: topped mulch film or nonwoven on its frame.Mulch film is grown seedlings and must be adopted this procedure of ventilation hardening; Nonwoven is grown seedlings because of its ventilation, thermal diffusivity is good, bed temperature is lower, can remove this procedure of ventilation hardening from, in case but also can cause seeding stage delay, little, the rice transplanting cold current attack on time of seedling, very easily cause freeze injury.
The purpose of this utility model is: at the problems referred to above, provides a kind of advantage of existing nonwoven, the advantage of mulch film arranged again, and keep away its two shortcoming, and the compound quilt of succeeding in developing of a kind of nonwoven mulch film.
The purpose of this utility model is achieved in that the compound quilt of a kind of nonwoven mulch film, comprises nonwoven and mulch film, it is characterized in that: be provided with fixedly rete and removable rete between nonwoven and the mulch film.
The utility model also can be achieved through the following technical solutions: the said fixing rete is located at the two sides of nonwoven and mulch film, and by adhesive or compression moulding the two is combined into one; Above-mentioned removable rete is made up of two mulch films, is located on the nonwoven, the middle joint form that partly is; The height of said fixing rete greatly the what seedling cultivation of rice be embedded in underground part sum.
The utility model further specifies by the following drawings and embodiment.
Fig. 1, be the utility model structural representation.
Fig. 2, be that the utility model implements illustration.
Referring to Fig. 1,2, the compound quilt of a kind of nonwoven mulch film, comprise nonwoven 3 and mulch film 1,2, be provided with fixedly rete 5 and removable rete 6 between nonwoven 3 and the mulch film 1,2, wherein fixedly rete 5 is located at a side of nonwoven 1,2, two sides of mulch film 3, and by adhesive or hot-forming the two is combined into one, has certain intensity; Its fixedly rete 5 height greatly what rice seedling 4 be embedded in underground part sum, it is highly generally in 300 millimeter, this fixedly rete 5 can play and keep out the wind, winter protection, prevent the problem that a seedling is short and small.
Above-mentioned removable rete 6 is made up of nonwoven 1,2, and it is located on the nonwoven 3, and middle part is joint form, can push aside or close.
During use, fixedly rete 5 a bit of is embedded in undergroundly, and all the other partly basset, and is higher than and grows seedlings 4.Installation method is seen Fig. 2, is grown a leaf when seedling, after the week, along with increasing of temperature, removable rete 6 is pushed aside a ventilating opening, regulate temperature in the bed, no longer cover night, grow up and temperature further increases along with rice shoot, can strengthen ventilating opening, directly cause and take off fixedly till rete 5 places; Before cold current arrives, but the removable rete 6 of pull-up is again closed ventilating opening, prevents that freeze injury from taking place, and what guarantee to grow seedlings grows.
Advantage of the present utility model and good effect are:
1. before the ventilation hardening, because the sealing process of removable rete has solved nonwoven and grown seedlings in earlier stage warm Spend the problem low, that seedling is little, guaranteed on time rice transplanting.
2. set up fixedly rete, solved nonwoven too small, the uneven problem of bedside seedling of growing seedlings.
3. keep nonwoven to grow seedlings, saved the problem of ventilation hardening recruitment.
4. the cost of the compound quilt of nonwoven mulch film is identical with the mulch film cost.
This utility model has vast market prospect, is applicable to various field management of growing seedlings.
