Abstract
The invention discloses a kind of salt affected soil cultivation degradable mulch, including being made of the raw material of following parts by weight：30~60 parts of ethylene acrylic, 20~40 parts of modified starch, 10~20 parts of sodium alginate, 0.5~5 part of photosensitizer, 0.5~1.5 part of plasticizer, 0.5~1.5 part of heat stabilizer, 0.5~1 part of graphene.The present invention is fast with degradation speed, the advantages of intensity is high since the Plastic-film disintegration speed is fast, does not pollute arable land, the structure of salt affected soil is not interfered with, is avoided and is aggravated to salt affected soil structural damage, is conducive to the growth of plant in the improvement and salt affected soil of salt affected soil.
Description
Technical field
The present invention relates to ground membrane technology more particularly to a kind of salt affected soil cultivation degradable mulch.
Background technology
As mulch uses on a large scale, a large amount of mulch fragments can remain in the soil.At present majority peasant households using
Nondegradable plastics film, because bright day illuminance is good, durable, extremely efficient in preserving heat.But nondegradable plastics film is difficult point
Solution, can not only destroy soil texture, influence plant growth and lead to the underproduction, can also cause Heavy environmental pollution.And salt affected soil
Physicochemical property itself it is poor, salt affected soil structure is destroyed, hard when sticking dry when wet, ventilation, it is permeable bad, in salt affected soil
Nutrient be largely lost in, such as using nondegradable plastics film, then can the salt affected soil above problem can be further aggravated, in this way
The growth of plant causes greatly to influence in improvement and salt affected soil for salt affected soil.
Invention content
The technical problems to be solved by the invention are to provide a kind of destruction that can avoid aggravating to salt affected soil, are conducive to
The salt affected soil cultivation degradable mulch of the growth of plant in the improvement of salt affected soil and salt affected soil.
In order to solve the above technical problems, the technical scheme is that：Salt affected soil cultivation degradable mulch, including by
The raw material of following parts by weight is made：30~60 parts of ethylene acrylic, 20~40 parts of modified starch, 10~20 parts of sodium alginate, light
Quick dose 0.5~5 part, 0.5~1.5 part of plasticizer, 0.5~1.5 part of heat stabilizer, 0.5~1 part of graphene.Graphene equally may be used
Play the role of photosensitizer, convenient for the degradation of this degradable mulch.The production of this salt affected soil cultivation degradable mulch uses
Conventional mulch film production method is produced.
The photosensitizer for cerium stearate, ferric stearate, N, N- dibutyl dithiocaarbamates iron, manganese stearate and N,
One or more of N- nickel dibutyl dithiocarbamates.
The plasticizer is tributyl citrate, tributyl 2-acetylcitrate, dioctyl phthalate, ethylene glycol and third
One or more of triol.
The heat stabilizer is one or more of zinc stearate, hydrotalcite and calcium stearate.
Further include 0.5~1.5 part of 0.5~1 part of raw material solubilizer, the antioxidant including following parts by weight.
The antioxidant is more than one of tea polyphenols, natural plant polyphenols, tris phosphite and triphenyl phosphite.
The solubilizer be in pentalyn, rosin glycerides and maleficent acid rosin resin it is a kind of with
On.
By adopting the above-described technical solution, the beneficial effects of the invention are as follows：This salt affected soil cultivation degradable mulch
Fast with degradation speed, the advantages of intensity is high, since the Plastic-film disintegration speed is fast, does not pollute arable land, does not interfere with saline and alkaline
The structure of soil avoids and aggravates to salt affected soil structural damage, is conducive to plant in the improvement and salt affected soil of salt affected soil
The growth of object.
