Abstract

The invention relates to a biodegradable plastic film which comprises a plastic film layer and a nutritive layer. The plastic film layer is mainly prepared from polyhydroxyalkanoates (PHA), thermoplastic starch and auxiliary ingredients; the nutritive layer is prepared from organic matter and plant fibers. The biodegradable plastic film has the structure characteristics that the nutritive layer is arranged inside the plastic film layer; and the nutritive layer and the plastic film layer are compounded into one whole body. The biodegradable plastic film can be degraded into water, carbon dioxide and organic matter by a plurality of aquatic bacteria, the environment pollution cannot be caused, the moisture evaporation can be reduced and the utilization rate of water is improved, so that the survival rate of crops is improved. Meanwhile, due to the adoption of the biodegradable plastic film, the soil can be improved, the soil fertility can be improved, and the output of the crops in the vast western drought regions can be effectively improved.

Description

A kind of Biodegradable mulch
Affiliated technical field
The present invention relates to a kind of Biodegradable mulch, belong to the agricultural film production technical field.
Background technology
Agricultural mulching is the important means of production of modern agriculture.Agricultural mulching have preserve moisture, effect such as insulation, help crop growth, improve crop yield, improve agriculture benefit.But in vast western arid area, like places such as Xinjiang, sunshine is stronger, and water evaporates is fast, and precipitation is few again, and the soil is barrenr, even use agricultural film, the raising of crop yield neither be very desirable.And traditional agricultural mulching processes with vinyon, and in natural environment, vinyon self is difficult to decompose; Be scattered in soil and the natural environment; Contaminated environment has been destroyed soil structure, makes that soil fertility weakens year by year, crop yield reduces; Western fragile ecology is caused bigger injury, be contrary to the strategy of sustainable development of country.
Summary of the invention
Vast arid area can not effectively improve crop yield and contaminated environment in order to solve traditional agricultural mulching in western part, destroy the problem of soil structure, the present invention provides a kind of Biodegradable mulch; This Biodegradable mulch can not only be incubated, preserve moisture, and reduces water evaporates, and has and improve the soil; The function of increasing soil fertility; Effectively improving the output of vast western arid area crops, and degradable, can not pollute the farmland.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Biodegradable mulch, comprise ground rete and nutritive layer, and the ground rete is mainly processed with gathering alkyl fatty acid ester (PHA), thermoplastic starch and complementary composition; Nutritive layer is processed by organic and vegetable fiber.Design feature be ground rete the inboard be provided with nutritive layer, and the two compound be one.Because this Biodegradable mulch can be by several aquatic bacteria degradation water, carbonic acid gas and organic matter, so can not pollute environment; Two tunic structures of this biological degradation nutrient film can reduce water evaporates more effectively in addition, improve the availability of water, and then improve the survival rate of crops; And the organic substance in the nutritive layer can also be improved the soil the fertility of raising soil, raising crop yield.
The invention has the beneficial effects as follows insulation, reduce water evaporates, improve the availability of water, improve the soil, increase soil fertility, effectively improve the output of vast western arid area crops, and can degrade, do not pollute the environment.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a structural representation of the present invention.
Among the figure: rete 1,, 2, nutritive layer.
Embodiment
In Fig. 1, this Biodegradable mulch comprises ground rete (1) and nutritive layer (2), and ground rete (1) is mainly processed with gathering alkyl fatty acid ester (PHA), thermoplastic starch and complementary composition, and nutritive layer (2) is processed by organic and vegetable fiber.Design feature be ground rete (1) the inboard be provided with nutritive layer (2), and the two compound be one.
Biodegradable mulch of the present invention covers to plant to be had on the ground of crops seedling, and two tunic structures of this biological degradation nutrient film can reduce water evaporates more effectively, improves the availability of water, and then improves the survival rate of crops.Along with growth of seedlings, nutritive layer (2) can be degraded into water and organic substance gradually, thereby increases soil fertility, and promotes the growth of crops.After the crops harvest, the ground rete of staying in the soil (1) also can be degraded, and can not damage soil structure, has avoided environmental pollution.

Claims (3)

1. a Biodegradable mulch comprises ground rete (1) and nutritive layer (2), and it is characterized in that: ground rete (1) is mainly processed with gathering alkyl fatty acid ester (PHA), thermoplastic starch and complementary composition.
2. Biodegradable mulch according to claim 1 is characterized in that: nutritive layer (2) is processed by organic and vegetable fiber.
3. Biodegradable mulch according to claim 1 is characterized in that: the inboard of ground rete (1) is provided with nutritive layer (2), and the two compound be one.
