The present invention discloses a kind of green covering material and its application method for inhibiting moisture evaporation for Arid&semi-arid area, primary raw material is water-soluble polylactic resin, it is added to the table chemical fertilizer of compounding, not only increase the water solubility of resin, and while solving water conservation, solve the problem of fertilization of crop, the covering material of powdery is dissolved in the water and is uniformly sprinkled upon farmland surface, form three-dimensional netted cross-linked layer, the effect of forming the very thin purpose for preventing evaporation layer from playing water-retaining effect in upper soll layer, while having both fertilising；The raw materials such as polylactic acid and other raw materials belong to green material, can it is degradable the 8-12 middle of the month be nontoxic small molecule material, remained without micro- plastics, safety and environmental protection, environmental sound is low in cost.
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
Green 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 green covering material and its application method for inhibiting moisture evaporation of Arid&semi-arid area, have after covering material use
Soil moisture conservation and fertilising the effect of, kill two birds with one stone, effectively reduce the usage amount and cost of chemical fertilizer, can be degradable, to environment without
Poison is harmless.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of green covering material for inhibiting moisture evaporation for Arid&semi-arid area, formula include water-soluble
Polylactic resin, the paraffin of resin quality 50-80ppm, the chemical fertilizer of resin quality 300ppm-2000ppm, resin quality
The surfactant of 0.05-0.8%, the fungicide of resin quality 50ppm, the chemical cross-linking agent of resin quality 0.2%；
By water-soluble polylactic resin, paraffin and chemical fertilizer high-temperature mixing, surfactant and chemistry is then added
Crosslinking agent is uniformly mixed smashing and grinding to granularity and obtains the covering material of powdery below 200 mesh.
Further, the chemical fertilizer is ammonium hydrogen carbonate, urea, potassium phosphate or its mixture.
Further, the chemical cross-linking agent is tertiary amine.
Further, the surfactant include lauryl sodium sulfate, neopelex, glycine betaine or its
Mixture.
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, by the covering material of powdery
Be dissolved in the water prepare mass percent concentration be 0.4-0.9% aqueous solution be uniformly sprinkled upon farmland surface, thickness control exists
0.2-0.7mm forms three-dimensional netted cross-linked layer in farmland surface, realizes water-retaining effect to soil.
The green covering material that inhibits moisture evaporation of the present invention for Arid&semi-arid area, formula primary raw material are
Water-soluble polylactic resin has preferable solubility due to its how special chemical structure in water, is added to a certain amount of
Paraffin increases its waterproofness, extends degradation cycle, is added to the chemical fertilizer of compounding, increases polylactic resin in water
Solubility applied so that the material has while having and placing evaporation so that he also has preferable solubility at low temperature
The function of fertilizer, is added to nontoxic chemical cross-linking agent, in order to increase adhesiveness between soil between molecular resin, drop
The degradation speed of low resin extends her validity period, is added to fungicide, reduces bacterium for the degradation speed of resin, extends
Her validity period.
The covering material of powdery 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 a three-dimensional netted cross-linked layer in 0.2-0.7mm, on the surface in farmland, in soil
Surface layer, which is formed, very thin prevents evaporation layer.The formula is mainly used in the soil in Arid&semi-arid area rural area field, plays guarantor
The purpose of water soil moisture conservation, while the effect of have both fertilising, the Water-saving effect and fertilising efficiency of dry farmland are improved, agriculture is effectively reduced
The construction cost of industry.And the raw materials such as polylactic acid used and other raw materials belong to green material, it can be complete the 8-12 middle of the month
Degradable is nontoxic small molecule material, is remained without micro- plastics, safety and environmental protection, and environmental sound is low in cost.
