Abstract
The utility model discloses and a kind ofly drought resisting can prevent the compound mulch film of the novel degradable of dirt, it is by first liquid ground rete, stalk cushion or wood chip cushion, and second liquid ground rete is composited.Of the present utility modelly drought resisting can prevent the compound mulch film of the novel degradable of dirt, break traditions the monofilm form of mulch film, adopt the three-layer composite structure of liquid ground film layer-stalk cushion (or wood chip cushion)-liquid ground film layer, by Double-layer liquid ground rete, stalk cushion (or wood chip cushion) is clipped in wherein, can dirt have been prevented.And the use of stalk cushion (or wood chip cushion) has following advantage, one is greatly improve mulch film heat and moisture preserving performance; Two is be beneficial to straw-returning, reduces crop straw burning and the problem of accumulation; The more important thing is and obviously can improve soil microbial community, Promoting plant growth.
Description
Technical field
The utility model relates to agricultural production application field, specifically a kind ofly drought resisting can prevent the compound mulch film of the novel degradable of dirt.
Background technology
Agricultural mulching is the important means of production of modern agriculture.Agricultural mulching has the effects such as moisturizing, insulation, pest-resistant, diseases prevention, suppression weed growth, is conducive to crop growth, improves crop yield, improves agricultural benefit.The application of ground membrane technology greatly facilitates the development of agricultural, but owing to using the dependence of mulch film, also causes numerous environment side effect simultaneously, is difficult to the plastics decomposed, soil structure is wrecked and causes environmental pollution and crop production reduction.Therefore, according to the requirement of sustainable development view, the mulch film meaning of development environment close friend is particularly great.Current mulch film can be divided into solid-state mulch film and liquid-state mulch film by form.Solid mulch film mostly is petroleum-based plastics and makes, and is not only difficult to degraded, and executes as agricultural paving and need to control film thickness, and then cause its price high and need certain cost of labor, and thus application is difficult to promote on a large scale.Liquid ground film is good due to degradation property, can spray the advantages such as film forming in scene, becomes alternative traditional mulch film optimal selection, but existing liquid-state mulch film, its heat and moisture preserving performance or not ideal, needs further improvement.
Utility model content
What the purpose of this utility model was to provide a kind of heat and moisture preserving better performances drought resisting can prevent the compound mulch film of the novel degradable of dirt.
To achieve these goals, the utility model adopts following technical scheme:
Drought resisting can prevent the compound mulch film of the novel degradable of dirt, by first liquid ground rete, stalk cushion or wood chip cushion, and second liquid ground rete is composited.
Described first liquid ground rete and described second liquid ground rete all adopt PE/Starch alcohol liquid ground film layer.
After adopting such scheme, of the present utility modelly drought resisting can prevent the compound mulch film of the novel degradable of dirt, break traditions the monofilm form of mulch film, adopt the three-layer composite structure of liquid ground film layer-stalk cushion (or wood chip cushion)-liquid ground film layer, by Double-layer liquid ground rete, stalk cushion (or wood chip cushion) is clipped in wherein, can dirt have been prevented.And the use of stalk cushion (or wood chip cushion) has following advantage, one is greatly improve mulch film heat and moisture preserving performance; Two is be beneficial to straw-returning, reduces crop straw burning and the problem of accumulation; The more important thing is and obviously can improve soil microbial community, Promoting plant growth.
Meanwhile, the stalk cushion in the utility model or wood chip cushion, raw material is easy to get, and cost is lower, thus makes compound mulch film of the present utility model have wide market prospects.

Embodiment
The utility model is a kind of drought resisting can prevent the compound mulch film of the novel degradable of dirt, as shown in Figure 1, is used in cultivation box 1, is composited by rete 2, cushion 3 and second liquid ground, first liquid ground rete 4.
Wherein, first liquid ground rete 2 and second liquid ground rete 4 all adopt PE/Starch alcohol liquid ground film layer, and thickness is 0.05-1mm.
PE/Starch alcohol liquid ground film layer is known Biodegradable mulch, as the phase " plastics industry " nineteen ninety the 03rd discloses " research of Polyvinyl Alcohol--starch Biodegradable Agriplast Film Materials " of Li Yunfei.
Cushion 2 adopts stalk cushion or wood chip cushion, and thickness is 25-250mm.The flour that stalk in stalk cushion adopts straw to be ground into.
During use, the inside of cushion 2 can allocate appropriate slow-release fertilizer particle 5 into according to plant growth demand.
During construction, the raw material of PE/Starch alcohol liquid ground film layer is loaded sprayer, and spraying liquid ground film process need carry out at twice, directly spray the earth's surface in cultivation box 1 for the first time, form second liquid ground rete 4, second time is then spray on cushion 3, forms first liquid ground rete 2.
After adopting such scheme, of the present utility modelly drought resisting can prevent the compound mulch film of the novel degradable of dirt, break traditions the monofilm form of mulch film, adopt the three-layer composite structure of liquid ground film layer-stalk cushion (or wood chip cushion)-liquid ground film layer, by two-layer liquid ground film layer, stalk cushion (or wood chip cushion) is clipped in wherein, can dirt have been prevented.And the use of stalk cushion (or wood chip cushion) has following advantage, one is greatly improve mulch film heat and moisture preserving performance; Two is be beneficial to straw-returning, reduces crop straw burning and the problem of accumulation; The more important thing is and obviously can improve soil microbial community, Promoting plant growth.
Meanwhile, the stalk cushion in the utility model or wood chip cushion, raw material is easy to get, and cost is lower, thus makes compound mulch film of the present utility model have wide market prospects.
Claims (2)
1. drought resisting can prevent the compound mulch film of the novel degradable of dirt, it is characterized in that: by first liquid ground rete, stalk cushion or wood chip cushion, and second liquid ground rete is composited.
2. according to claim 1ly a kind ofly drought resisting can prevent the compound mulch film of the novel degradable of dirt, it is characterized in that: above-mentioned first liquid ground rete and above-mentioned second liquid ground rete all adopt PE/Starch alcohol liquid ground film layer.
