Abstract
The invention provides biodegradable liquid mulching film powder, which is a liquid mulching film formed by using multiple macromolecular polymers and humic acid raw materials and combining microbial bacterial, subjected to superfine treatment and water dilution and sprayed while sowing. The biodegradable liquid mulching film powder forms film blocks, holds water, retains humidity, preserves heat, and can form biological organic fertilizer after degradation to increase both production and income. The biodegradable liquid mulching film powder has the advantages of simple and convenient manufacturing process, easily purchased raw materials and low cost.
Description
Technical field
The present invention relates to a kind of Biodegradable liquid mulching film powder in the agricultural film technical field, be to utilize high molecular weight water soluble polymer, humic acids, microbial bacteria, after handling, series of processes is diluted to pasty state, with a kind of liquid mulching film powder of atomizers spray in the field with water.
Technical background
In recent years, the domestic use that the liquid mulch film of many humic acidss is arranged, this liquid-state mulch film sprays into alternative traditional plastic film behind the field, can play the effect of bio-fertilizer after the degraded again, but some liquid-state mulch film is after drenching with rain, pellicle is washed away and has been lost the effect of film, and cohesiveness, the toughness of this film are relatively poor, and the liquid film that has does not just have the effect of film at all.The present invention researches and develops a kind of novel Biodegradable liquid mulching film powder, to satisfy the mulch film demand of different tillage on the basis of former liquid film.
Summary of the invention
Order of the present invention ground is can pass through biodegradable liquid-state mulch film for vast farmers plantation family provides a kind of.Manufacturing the reasonableness that the Biodegradable liquid mulching film key is tackiness agent and dosage, also is the key point of material combined prod quality.Below just the manufacture technology of Biodegradable liquid mulching film powder of the present invention is done one and specifies:
1, polyvinyl alcohol powder (PVA), belong to the cold soluble type high molecular polymer, the easy film forming of its film-forming properties PVA, the mechanical property of film is good, and the drawing of film stretched intensity and raise with the polymerization degree, alcoholysis degree and strengthen, because the fineness of PVA powder is 120 orders, just can dissolve at normal temperature tap water below 35 ℃, need not heat treated, therefore, utilize the binder for film formation of polyvinyl alcohol powder as liquid-state mulch film, various plant amylum tackiness agents can't be compared.
2; Xylo-Mucine (CMC) has emulsifying dispersivity, solid dispersed; be difficult for corrupt; harmless and unusual and valuable comprehensive physicochemical property on the physiology; be output maximum in the fiber ethers, purposes is the widest, uses product the most easily; be commonly called as " industrial monosodium glutamate ", its key property is to form full-bodied colloid, and solution has adhesion; thickening is flowed, and emulsification disperses; stability, figuration, water conservation; protective colloid, film forming, anti-high inorganic salt; hang characteristics such as turbid, therefore, at food; medicine, daily use chemicals, oil; papermaking; weaving, building, fields such as agriculture aspect obtain extensive use.
3, humic acid material is the coal mud in underground hundreds of millions years of being sunk into sleep, and needs to add the functional group that special-purpose microorganism activator activates dormancy.Contain acidic functionality materials such as aromatic proton, hydroxyl, carboxyl, carbonyl in the humic acid material, synthetic and on the face of land, form thin film with tackiness agent, nitrogen in the soil, phosphorus, potassium element can be carried out the biochemical reaction of series, form new ionic group, also be complex compound, like this, not only improved the activity of phosphorus potassium element, several mineral materials in again can activating soil is converted into inorganic nutrients, for the plant absorbing utilization.
4, microbial bacteria, false simple bud born of the same parents bacillus, colloid bacillus is the special bacterium of special decomposition and humic mineral grain, after humic acid material is mixed, can decompose the mineral plasmid, activate functional group's organic substance of dormancy, with the interaction of multiple tackiness agent under, make its in short duration progressively Degradation and Transformation be bio-organic fertilizer.
5, a kind of Biodegradable liquid mulching film powder of the present invention, with polyvinyl alcohol (PVA) powder, Xylo-Mucine (CMC), the humic acid material powder after microbial bacteria is mixed in proportion, is 120 orders through superfine grinding, metering packing, every barrel of 10KG can spray 1 mu of ground.
Using method is that elder generation with 100 mesh filter screen bag filtrations once, puts in the atomizer after liquid mulching film powder 10KG is also fully stirred 20 minutes with 6 times clear water dilution then, gives enough air pressure, a kind of liquid film of spread by hand.The present invention divides black and white two kinds of colors, raw material, metering, resemble process.After liquid state is sprayed at soil surface, about 6-12 hour completely solidified, formation one deck mucous membrane, bio-fertilizer are the ecological degradative membrane of one, through nonirrigated farmland, field more than a year, the spray film test of Different Crop, experiment effect is as follows:
(1) because the covering of film, soil granular increases, and moisture content keeps 85% not evaporate, and the temperature in the soil in the 20cm is than the high 3-9 of soil temperature ℃ of hydrojet film not;
(2) seed germination is fast, shifts to an earlier date 3-5 days than general planting method and emerges;
(3) the seedling strain in vegetative period is sturdy, leaf is green in great numbers, and disease and pest reduces;
(4) growth is during the middle and later periods, and liquid film is progressively degraded, and changes bio-feritlizer into;
(5) various farm crop: corn, wheat, Chinese sorghum, millet, soybean, peanut, Hu Luobu, Chinese cabbage, spinach, than
(6) the general planting method is on average increased production 10-26%.
Experiment shows, sprays liquid-state mulch film, has not only substituted traditional mulch film, and has not had environmental pollution, can increase the output of various farm crop simultaneously, makes the peasant really experience the substantive order ground of increasing both production and income benefit.
Embodiment
A kind of Biodegradable liquid mulching film powder, its making method is:
1, with polyvinyl alcohol powder 10kg, cellulose sodium carboxymethyl 5kg, humic acid material 85kg, false simple bud spore bacillus mycelia 5g, colloid bacillus cereus mycelia 5g after the mixing, puts into and pulverizes 120 orders in the ultrafine crusher;
2, the material powder after will pulverizing, with the metering of every bag of 10kg, the plastic bag sealing of packing into putting into paper bucket inner sealing warehouse-in, promptly becomes a kind of Biodegradable liquid mulching film powder.
Claims (2)
