Description
Technical field
The present invention relates to agricultural installations Material Field, the preparation method of a kind of fiber paper base mulch film.
Background technology
The extensively application of plastic film, to improving crop yield, quality, solves extremely frigid zones and shifts to an earlier date nursery, plantation, with
And plantation anti-season vegetable, melon and fruit etc. play very important effect, the use advantage of agricultural film is a lot, but its molecular structure ten
Divide stable, be difficult to biodegradation or light degradation voluntarily under natural environment, not only pollute environment and also make farm output and quality
Being affected, the recycling of mulch film cost of wasting time and energy is the highest, and general mulch film can exist more than 2 hundred to three hundred in soil
Year is non-degradable.In recent years, starch addition type Biodegradable mulch, photodegradation film, Plant fiber ground have the most been developed
Film, liquid-state mulch film etc..The primary raw material that wherein starch addition type Biodegradable mulch and photodegradation film use remains plastics
And chemical fibre, it is impossible to eradicate " white pollution " problem completely；Plant fiber mulch is primarily referred to as paper mulch sheet；Mainly use paper maker
Skill makes paper mulch film, and it is a kind of environment-friendly type mulch film that can be degradable in soil.There is wind resistance rain ability, easily in paper mulch film
Broken, the problem such as inapplicable machinery plastic film mulch.Japan develops the paper mulch sheet of different purposes, and such as fiber net type paper mulch film, it is
With Plant fiber as primary raw material, it simply being placed into the soil after using, the antibacterial in soil just can be decomposed.
Organic fertilizer type paper mulch film is to be mixed with natural organic phosphatic fertiliser and natural antimicrobial substance in common paper mulch film, is suitable for
In extensive range, can be to add containing chitosan and fiber in paper mulch film with the use of biochemical type paper mulch film with variety classes crop
The compositions such as element, can promote the breeding of the soil bacteria favourable to crop growth, otherwise, the propagation to virus disease has control
With natural control effect, but owing to paper mulch sheet price is the most expensive, use less.New Zealand Murray Cmick shank company grinds
Make the Eco.Cover paper mulch film developed in 2,004 2006 years successively in 21, New Zealand, the U.S., European Union, Canada, Germany etc.
Country is patented.Paper ground film strength and service life different because of the thickness of film, the degradable time 6 24 months it
Between, can need to change properties of product according to production, the primary raw material of this paper mulch film is waste paper, can 100% be biodegradable, cover
Lid can reduce moisture evaporation 75%, effectively suppresses weeds, reduces soil erosion, increases soil fertility, promotes plant growing.Additionally
The waste liquids such as black liquid are modified by degradable liquid-state mulch film with brown coal, weathered coal or peat, by lignin, cellulose and
Polysaccharide forms macromolecule under the effect of cross-linking agent, then mixes system with various additives, siliceous fertilizer trace element, pesticide and herbicide
Taking acquisition, the insulation soil moisture conservation effect of this kind of mulch film is poor.
According to statistics, more than 50 ten thousand tons of the discarded natural fiber such as cotton that China produces every year, fiber crops, viscose glue, silkworm silk, and increase year by year
Adding, these garbages not only endanger environment, and cause the biggest wasting of resources.As these discarded natural fibers are made agriculture
Film, uses about the 10% of total amount by alternative macromolecule agricultural film.The non-woven agricultural film of textile fabric relative to other kinds of can
Degradative plastic film, the huge superiority of non-woven mulch film is that its biodegradability, and catabolite can also increase
The fertilizer matter of soil, meets the requirement of " ecological agriculture ".But the technology of plant fiber mulch is the most immature, combination property
There is also many shortcomings, also have with a certain distance from practical；Therefore need to design a kind of environmental protection, price relatively low, high insulating effect
Fiber paper base mulch film.
