For the growth quality of vegetables, it is recommended to ensure the quality of po film

  From the perspective of farmers' current habit and acceptance, in accordance with the regularity of rural waste recycling, we should vigorously improve the scope, carrying capacity and convenience of acquisition points, maintain the frequent acquisition points in villages, and carry out service projects around the requirements of farmers' disposal and disposal of waste PO films. Keep showing it to farmers as much as possible. po film is a more common kind of planting industry today, compared with the general agricultural mulch, it has stronger light transmittance, stronger heat insulation and longer service life. However, after all, po film is only a thin layer of agricultural plastic film, and the service life is present from beginning to end, but po film can be comprehensively used.

In order to prevent the selection of shoddy plastic greenhouse film products, people can go to some of the more well-known and reliable plastic greenhouse film manufacturers to carry out the selection. It is also necessary to master the actual effect and quality of the anti-aging basic raw materials often used in the production and manufacturing of po film greenhouse film manufacturers. General greenhouse film anti-aging basic raw materials include plasmid carrier epoxy resin and basic epoxy resin. The selection of epoxy resin for plasmid carrier is based not only on the characteristic compressive strength of PE greenhouse film, but also on the practical effect of better dispersion.

When choosing po film, it can be distinguished by combustion, if it is very smelly after ignition, with a nose smell, and taking a lot of black smoke from the exhaust pipe, dripping out a lot of gray and black flocculent, the material of this kind of greenhouse film is PVC, if it is marked as PE, EVA, it will be added in the production of some particles, the quality is not very good.

Choose the type of vegetables. Greenhouse vegetable planting and cultivation, the type of regulations are more stringent. Winter warm greenhouse cultivation of luffa, to choose the type of low temperature resistance, dark light; Spring shed cultivation of spring and winter vegetables and fruits, to choose the early resistance to low temperature, dark light, mature, in the middle and late can integrate into the high temperature natural environment, disease resistance, high yield types; Greenhouse po film greenhouse delayed time cultivation, to choose the early heat resistance, disease resistance, low temperature resistance in the middle and late period, and the results are more concentrated types. po membrane shed type construction. According to the local climate standards, cultivation season, production and manufacturing levels and economic selection of the shed, the slope of the ceiling and the road surface of the vegetable greenhouse is not less than 25 degrees, which is to ensure that the greenhouse vegetable planting yield, high quality, one of the important countermeasures. Several kinds of countermeasures to promote the high yield of greenhouse planting.
