Description
Technical field
The present invention relates to agricultural productions, and in particular to a kind of to inhibit moisture to evaporate for Arid&semi-arid area
Polylactic resin covering material and its application method.
Background technique
The agriculture producing region in the north of China, facing maximum problem is exactly water shortage.Water shortage is first is that rainwater is few；Two are a lack of effectively
Water source；Third is that evaporation capacity is too big, often evaporation capacity is greater than rainfall, leads to arid, the ecosystem of this part is very fragile.
Agricultural production is hovered in low-level for a long time.Due to 1/5th for possessing water per capita and there was only the world of our countries, belong to
Poor-water country.The water shortage problem of arid area is cracked, most real, least cost is exactly to reduce volatile quantity.
Traditional method for preventing moisture from evaporating is covering mulch, and polyethylene ground film is as a kind of important means of agricultural production, for north
The grain yield increase of side has served very big.But it due to the non-biodegradable of polyethylene ground film, is brought after use
Serious future trouble, one is observable mulch residual, second is that invisible micro- plastics problem, third is that still having in farmland invisible
Chemical substance-plasticizer of being always or usually as specified.The residual of recycled plastic film although government tries every possible means, is limited by cost and technology, mesh
It is preceding thorough to solve the problems, such as mulch film residues not no good method substantially.
Future continues to use polyethylene ground film, and micro- plastics that polyethylene ground film is formed first can step into following for living nature
Ring, following environmental risk can not temporarily be assessed, second is that as micro- plastics are in continuous accumulation in farmland, it is likely that cause soil
Discarded, arable land will gradually lose farming value.Mulch film residues problem is not only concerning the Food Security and country for arriving country
Strategic security problem, also concerning to national future.
Summary of the invention
Of the existing technology in order to solve the problems, such as, it is an object of that present invention to provide a kind of low in cost, preparation simplicity
For the polylactic resin covering material and its application method for inhibiting moisture evaporation of Arid&semi-arid area, covering material is used
Have effects that preserve soil moisture afterwards and apply fertilizer, kills two birds with one stone, effectively reduce the usage amount and cost of chemical fertilizer, can be degradable, it is right
Environment is nontoxic.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of polylactic resin covering material for inhibiting moisture evaporation for Arid&semi-arid area, formula include water
The polylactic resin of dissolubility, the paraffin of resin quality 50-80ppm, the chemical fertilizer of resin quality 300ppm-2000ppm, resin
The fungicide of quality 60ppm, the surfactant of resin quality 0.02-0.5%, the chemical cross-linking agent of resin quality 0.2%.
Further, the chemical cross-linking agent is tertiary amine.
Further, the chemical fertilizer is ammonium hydrogen carbonate, urea, potassium phosphate or its mixture.
Further, the surfactant include lauryl sodium sulfate, neopelex, glycine betaine or its
Mixture.
Further, the formula further includes the fungicide of resin quality 60ppm.
Further, the fungicide is sodium benzoate or quaternary ammonium salt fungicide.
A kind of covering material application method inhibiting moisture evaporation for Arid&semi-arid area, will be good by recipe configuration
Covering material is dissolved in the water, and is prepared into the aqueous solution that mass percent concentration is 0.4-0.9% and is uniformly sprinkled upon farmland surface,
Thickness control forms three-dimensional netted cross-linked layer in farmland surface in 0.2-0.7mm, realizes water-retaining effect to soil.
The polylactic resin covering material that inhibits moisture evaporation of the present invention for Arid&semi-arid area, primary raw material are
Water-soluble polylactic resin has preferable solubility in water, a certain amount of paraffin is added in formula, increases its waterproof
Property, extend degradation cycle, be added to the chemical fertilizer of compounding, increase solubility of the polylactic resin in water so that he
Also there is preferable solubility under low temperature, while the material being made to have the function of fertilising while having prevents evaporation；Addition
Nontoxic chemical cross-linking agent in order to increase adhesiveness between soil between molecular resin reduces the degradation of resin
Speed, extended validity period.
Further, in poly-lactic acid material, it is added to fungicide, bacterium is reduced for the degradation speed of resin, extends his
Validity period.
Configured covering material is dissolved in the water, and it is uniform to prepare the aqueous solution that mass percent concentration is 0.4-0.9%
It is sprinkled upon farmland surface, thickness control forms three-dimensional netted cross-linked layer on the surface in farmland, in upper soll layer in 0.8mm or so
Being formed very thin prevents evaporation layer.The formula not only has effects that preventing moisture from evaporating guarantees soil moisture, and has and apply
Effect of fertilizer, effectively reduces the use cost and amount of chemical fertilizer, has saved the construction cost in farmland, and improve chemical fertilizer uses function
Effect.
Applied to Arid&semi-arid area rural area field, soil water-retaining soil moisture conservation and fertilising purpose, and the high score used are played
Sub- material and other raw materials belong to green material, can be degradable for nontoxic small molecule material the 8-12 middle of the month
Material, remains, safety and environmental protection without micro- plastics, and environmental sound is low in cost.
