Description
The technical field is as follows:
the utility model belongs to the technical field of the agricultural plastic film, especially, relate to a hydrophilic plastic film takes a breath.
Background art:
the agricultural mulching film technology is generally applied to agricultural production in China, and the traditional mulching film technology mainly adopts a polyethylene or polyvinyl chloride high-molecular mulching film to cover the surface of soil, so that the soil temperature can be effectively increased, the soil moisture can be effectively maintained, and the aim of promoting agricultural high yield is fulfilled. However, the conventional polymer mulching film such as polyethylene or polyvinyl chloride often has the following two problems: one is that the traditional mulching film can not exchange air and the other is that the traditional mulching film is easy to generate water drops. The following explains these two problems: (1) the polyethylene or polyvinyl chloride high polymer plastic film that uses at present is mostly the plastic film of hydrophobic polymer material, lays the monoblock plastic film on soil surface during the use, accomplishes the plastic film and lays the operation promptly. However, the plastic mulching film is not breathable, so that a closed environment is formed in the space covered by the plastic mulching film, and although the closed space can play a role in inhibiting moisture evaporation in soil, the air in the space covered by the plastic mulching film cannot be exchanged with the air in the outside. The growth and development of crops require respiration, i.e. crops are sucked into CO in the environment under the action of photosynthesis2Introduction of CO into2Converting into nutrients required by crops, and ventilating the crops in a closed space if the crops are not ventilated in time2The gas concentration will decrease continuously when the CO is in the environment2When the concentration is less than 300ppm, the photosynthesis of crops is inhibited, and the slow growth of vegetables is causedFlower and fruit dropping, yield reduction and the like. In addition, fertilizers are frequently used in agricultural soil to promote crop growth, but harmful gases such as ammonia gas and the like can be released in the chemical change process of the fertilizers in the soil, and if the harmful gases such as ammonia gas and the like cannot be discharged in time in the traditional mulching film covered closed space, the harmful gases such as ammonia gas and the like in the mulching film covered closed space are accumulated to a high concentration continuously, and vegetable plants are easy to die. (2) The water drops formed by the agricultural mulching film are also large in damage to agricultural production, on one hand, the water drops reduce the possibility that sunlight enters the mulching film, the temperature of soil covered by the mulching film can be reduced, the soil is not beneficial to growth of crops, and on the other hand, because the water drops formed by the mulching film are spherical, the phenomenon of seedling burning is easily caused due to the fact that the spherical water drops converge scorched sunlight.
Document 1 (patent No. 2020202046049) proposes a breathable and heat-absorbing liquid rubber-based mulching film comprising a polyvinyl film having upper and lower surfaces, respectively, and a humic acid-containing heat-absorbing film sandwiched between the two polyvinyl films, wherein spherical negative heat materials are uniformly distributed in the humic acid-containing heat-absorbing film. The mulching film disclosed in the document 1 can absorb heat efficiently, and the pore size of the surface of the mulching film can change along with the change of the environmental temperature, so that the air permeability of the mulching film is automatically adjusted by utilizing the environmental temperature correspondingly. However, since humic acid is a black organic matter, the mulching film described in document 1 is also black, and although the black mulching film can effectively prevent the problem of weed damage by inhibiting photosynthesis of weeds, it also makes sunlight not easily penetrate through the black mulching film proposed in document 1 to directly irradiate the soil, so that the black mulching film proposed in document 1 is not preferable for raising the temperature of the soil, which is disadvantageous for root development of some crops like melons and solanaceous fruits which prefer high soil temperature. In addition, the surface of the mulching film proposed in the document 1 is composed of hydrophobic polyethylene macromolecules, so that water drops are easy to form on the surface facing the soil when the mulching film is used, namely, the mulching film disclosed in the document 1 does not have the property of preventing spherical water drops.
