Abstract
The invention discloses a biodegradable liquid agricultural film, and relates to a liquid ground film. The invention aims at solving the problems that the existing liquid ground film contains a great amount of petroleum derivatives, is not easy to be degraded, can harden soil and generate toxicity after a long term application, and the raw material resource is limited and the cost is comparatively high. The liquid agricultural film of the invention is made from 10 portions to 50 portions of plant straw, more than 0 portion to 30 portions of humic acid, 30 portions to 70 portions of water, 3 portions to 15 portions of film-forming agent, 0.5 portion to 1 portion of surfactant, more than 0 portion to 20 portions of fertilizer and more than 0 portion to 20 portions of stabilizer by weight. The liquid agricultural film of the invention can carry out spraying and film-forming by ordinary sprayers, thus saving labor, time and energy and avoiding the labor of seedling placing and waste film collection. After 2 months to 3 months, the agricultural film starts to be degraded into organic fertilizer of humic acid and the final degradation product is carbon dioxide and water. The agricultural film can be complexed with fertilizers and pesticides to prolong the fertilization effect and drug effect. The ground temperature can be increased by 1 DEG C to 6 DEG C and the crop output can be increased by 6 percent to 50 percent.
Description
Technical field
The present invention relates to a kind of liquid ground film.
Background technology
Production has brought once technical change to traditional agriculture in the widespread use of twentieth century plastic film.But its plastic molecules Stability Analysis of Structures of plastic film, be difficult to degraded, can influence land quality, influence crop absorption nutrient and moisture as being discarded in a large number in the soil.The harm that plastic film causes for soil, environment has caused the great attention of many countries.As far back as the seventies in 20th century, the La Baifeina research centre of Petrofina SA and Ghent, Belgium university joint research and development have gone out the agricultural liquid mulch film, because the liquid ground film product at initial stage contains a large amount of petroleum derivatives, be difficult for decomposing, life-time service can make soil compaction and toxigenicity, and raw material sources are restricted and cost is higher.
Summary of the invention
The objective of the invention is to contain a large amount of petroleum derivatives for solving existing liquid ground film product, be difficult for decomposing, life-time service can make soil compaction and toxigenicity, and raw material sources are restricted and the cost problem of higher, and a kind of Biodegradable liquid agricultural film is provided.The present invention part is made by 10～50 parts of straws, humic acid＞0～30 part, 30～70 parts in water, 3～15 parts of membrane-forming agents, 0.5～1 part in tensio-active agent, fertilizer＞0～20 part and stablizer＞0～20 by weight.The making method of liquid agricultural film of the present invention is: one, straw is joined content and be in 5% the sodium hydroxide solution, boiled 35～55 minutes under 100～110 ℃, 0.1～0.5Mpa pressure condition; Two, in the product of step 1, add humic acid, under 90～100 ℃ of conditions, boiled 20～40 minutes; Three, in the product of step 2, add membrane-forming agent, under 90～100 ℃ of conditions, boiled again 10～30 minutes; Four, add tensio-active agent and stablizer after the product of step 3 is cooled to 75～85 ℃, stirred then 10～20 minutes; Five, add fertilizer in the product of step 4 and continue to stir, liquid cooling to 30～35 ℃ stop to stir, and room temperature preservation gets final product.
Beneficial effect of the present invention: one, can spray with common sprayer and make film, form thin film at soil surface, the saving of labor, save time, laborsaving, only just can finish (lay plastic film and need three to four people), and remove from and put the give up work of film of seedling, receipts with a people.Two, environmental protection begins to be degraded to the humic acids fertilizer through 2～3 months plastic sheeting for farm uses after laying (film forming) is finished, and the final product of degraded is carbonic acid gas and water, has eradicated white pollution.Three, be converted into the humic acids fertilizer behind the multi-efficiency, plastic sheeting for farm use degraded, can with chemical fertilizer, agricultural chemicals complexing, prolong fertilizer efficiency, drug effect.Four, ventilative, permeable, can improve photosynthesis, transpiration and the respiration of farm crop, guarantee the ventilative and breathing of crop root part.Five, improve ground temperature, soil moisture conservation, compare with plastic film and can improve 1～6 ℃ of ground temperature, improve crop yield 6～50%.
