Abstract
The invention discloses a paste-type degradable plastic film and belongs to the agricultural plastic film production field. Humic acid, film forming agents, surfactants, modifiers, fertilizers and water are used to prepare black or brown paste; the paste is then diluted by water and sprayed out to form a film-shaped structure on the soil surface. Compared with the prior art, the paste-type degradable plastic film of the invention has low cost, good effect, convenient packaging and transportation, as well as good promotion and application value.
Description
Technical field
The present invention relates to a kind of agricultural mulching, specifically a kind of by spraying the pasty degradable mulch film that can form membrane structure.
Background technology
The widespread use of agripast film-mulching technique has been played vital role to improving crop yield.Yet this technology has brought serious " white pollution " also for soil and environment when bringing enormous benefits to agricultural produce.It is embodied in: influence the formation of soil microorganisms activity and soil normal configuration, cause soil fertility to descend; Residual mulch film has produced detrimentally affect to the physical behavior of soil, causes crop root to become the bending development, causes root system to shorten, absorb water, inhale fertile performance and reduces, and causes crop failure; Mulch film remains in the soil or abandons in the edge of a field edge of a field, causes environmental pollution.Therefore study degradable mulch is the very interested project of scientists always.Degradable mulch of the prior art mainly is divided into two classes: the mulch film that liquid ground film and calendering or blowing are made.The former is easy to use, can the scene spray and make film, but production cost is higher, and packing and trucking costs are also high, as patent publication No. disclosed " all-degradable liquid mulch film " in the patent documentation of CN 101007903A, the aqueous colloidal solution that a kind of exactly physical mixed forms; The latter needs artificial laying, peripheral firming, use inconvenience, and production cost is also higher.
Summary of the invention
Technical assignment of the present invention is at above-mentioned the deficiencies in the prior art, provide a kind of low cost, effective, be convenient to the pasty degradable mulch film packing and transport.
Technical assignment of the present invention is realized in the following manner: with humic-acid kind, membrane-forming agent, tensio-active agent, properties-correcting agent, fertilizer etc. is the major function composition, by the pasty degradable mulch film of operations such as chemical reaction, mixing generation.Wherein, properties-correcting agent is cheap humic-acid kind to be converted into be easier to the humic acids salt of plant absorbing and make it film-forming properties improve; The effect of membrane-forming agent, tensio-active agent be make it to obtain easily in process of production paste and spray after easier film forming; Fertilizer then can provide suitable nutrition for plant-growth.
Pasty degradable mulch film, it is black or the brown lotion that is prepared by humic-acid kind, membrane-forming agent, tensio-active agent, properties-correcting agent, fertilizer and water, after this lotion dilute with water, the sprinkling, can form membrane structure at soil surface.
The amount ranges of each composition of the present invention draws through contriver's the summary of groping in a large number, and the weight part proportioning of each raw material is for all there being effect preferably in following ranges:
Humic-acid kind: 20～60 parts
Membrane-forming agent: 0.25～20 part
Tensio-active agent: 0.1～20 part
Properties-correcting agent: 0.5～30 part
Fertilizer: 0～15 part
Water: 30～60 parts.
The preferred weight part ratio range of each raw material is:
Humic-acid kind: 30～45 parts
Membrane-forming agent: 5～15 parts
Tensio-active agent: 1～10 part
Properties-correcting agent: 5～20 parts
Fertilizer: 0～15 part
Water: 35～55 parts.
Described humic-acid kind is the mixture of one or more materials in weathered coal, brown coal, the humic acids.
Described membrane-forming agent is the mixture of one or more materials in polyvinyl alcohol, carboxymethyl cellulose, Natvosol, polyacrylamide, sodium silicate, potash water glass, starch, the treated starch.
Described tensio-active agent is the mixture of one or more materials in octadecyl trimethyl ammonium chloride, stearylamine Soxylat A 25-7, polyoxyethylene sorbitan monolaurate, diethanolamine of fat acyl, polyoxyethylenated alcohol sodium sulfate, AESA, aliphatic alcohol polyoxyvinethene phosphate salt, the sodium lauryl sulphate.
Described properties-correcting agent is sodium hydroxide and/or potassium hydroxide.
Described fertilizer is the mixture of one or more fertilizer in nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, fertiliser containing magnesium, iron fertilizer, boron fertilizer, zinc fertilizer, siliceous fertilizer, copper fertilizer, the manganese fertilizer.
The preparation method of mulch film of the present invention may further comprise the steps:
A, the water with formula ratio, humic-acid kind and properties-correcting agent add reactor, react 1～2 hour down at 80～100 ℃;
B, the membrane-forming agent with formula ratio, tensio-active agent and fertilizer add in the reactor, mix, and discharging gets product after the cooling.
Degradable mulch of the present invention at first with its water dilution with 4～6 times of amounts, directly sprays in soil surface with atomizer then and can form membrane structure in use.
Pasty degradable mulch film of the present invention compared with prior art has following outstanding beneficial effect:
(1) not only easy to use, dilution can form membrane structure at soil surface after spraying, play the effect of membrane covering, and has a Degradation of general light or organisms, after using, can degrade voluntarily, when avoiding white pollution, can also provide an amount of fertilizer and inorganic fertilizer for soil;
(2) the paste product is more conducive to packing and transportation, and cost is low;
(3) increase properties-correcting agent, properties-correcting agent produces chemical reaction with humic-acid kind, generation Sodium salts humic acids or potassium humate, thus absorbed easilier by crop, and film-forming properties is better.
