Abstract
The present invention discloses a liquid-state mulching film forming material and a preparation method thereof. The liquid-state mulching film forming material comprises sea-tangle powder, starch phosphates, alpha starch and ammonium carbonate; the preparation method comprises the steps that sea tangles are pickled and are decolored, and then, the sea tangles are cut up; the ammonium carbonate, the starch phosphates and the alpha starch are added; the mixed material is put in a kneader or a screw extruder for milling, granulation and drying. The liquid-state mulching film forming material contains no biological high molecular material or fertilizer and has no adverse effect on plant growth environment of soil, groundwater, etc. The ineffective film residue can improve the organic matter content of the soil in a short time, improve the aggregate structure of the soil, and fix the surface soil.
Description
Technical field
The present invention relates to a kind of liquid state mulching film forming material and preparation method thereof, particularly a kind of degradable biological liquid state mulching film forming material and preparation method thereof.
Background technology
At present, the overwhelming majority of using in the agriculture production is still for being difficult to the polyethylene ground film of degraded.In order to reduce the covering expense, film thickness has been reduced to below 10 microns, reclaims for residual film and causes very big difficulty, has aggravated the pollution of residual film to the farmland.The degradable plastics mulch film mainly contains disintegration-type and two kinds of forms of photodegradation type, but all in aspects such as intensity, cost and degradation characteristic existing problems, has limited its widespread use.
Summary of the invention
The degradable biological liquid state mulching film forming material and the manufacture method thereof that the objective of the invention is to provide a kind of suitable sprinkling and extrude operation form.

(2) use 10%H
2O
2Soak and send out good sea-tangle 5～8 hours;
(3) will soak the sea-tangle chopping of decolouring to 5～8 millimeters;
(4) add volatile salt (NH respectively by 8%～15%, 80%～150%, 20～60% of dried sea-tangle quality
4HCO
3NH
2COONH
4), starch phosphates, α starch;
(5), put into kneader or screw extruder is mixing with above-mentioned material mixing;
(6) granulation, drying.
Biological liquid mulching film forming material of the present invention is the degradable mulch material, comprise bioabsorbable polymer material and chemical fertilizer, crop growth environments such as soil underground water are had no adverse effect, and the resistates of the film after losing efficacy can improve the organic content of soil in a short time, improve the crumb structure of soil, fixed table soil.
Specific embodiments
Biological liquid mulching film forming material of the present invention comprises sea-tangle, starch phosphates, α starch and volatile salt (NH
4HCO
3NH
2COONH
4) four kinds of compositions, in kneader and screw extruder, adopt the semidrying reaction to make.Wherein the content of starch phosphates is 100% of sea-tangle opaque amount, and the α contents of starch is 50% of a sea-tangle opaque amount, and the content of volatile salt is 10% of sea-tangle opaque amount.
The preparation method of above-mentioned biological liquid mulching film forming material comprises:
(1) dried sea-tangle is steeped 5～6 times that send to proper mass;
(2) use 10%H
2O
2Soak and send out good sea-tangle 5～8 hours;
(3) will soak the sea-tangle chopping of decolouring to 5～8 millimeters;
(4) add volatile salt (NH respectively by 10%, 100%, 50% of dried sea-tangle quality
4HCO
3NH
2COONH
4), starch phosphates, α starch;
(5), put into kneader or screw extruder is mixing with above-mentioned material mixing;
(6) granulation makes particulate minimum size d
Min≤ 3mm;
(7) drying.
Biomaterial liquid-state mulch film of the present invention is a kind of novel mulch film of substituted for plastic mulch film.But film forming material water furnishing slurry, and by spraying and extruding two kinds of operation forms and finish moulding and lay in the field, form membrane is respectively macroscopical integral membrane (reticular membrane) and whole closely knit film (banded film).The wet film and the face of land form multiple spot bonding and point of suppon, and tack is good.The film main component is natural organic high-molecular and chemical fertilizer, film after the inefficacy can be decomposed into lower-molecular substances such as water, carbonic acid gas under the combined action of light, gas, water, microorganism, crop growth environments such as soil, underground water are had no adverse effect, will thoroughly solve the degradation problem of mulch film.Simultaneously, film forming material enters soil, will increase the organic content of soil, improves the crumb structure of soil.In addition, reticular membrane is fixed table soil effectively, and control table soil runs off and airborne dust.
