According to the characteristics of Jiaoguai glare, the light management adopts Shandong Hepai EVA multi-functional shed film, and hangs the reflective curtain on the back wall, and exposes the straw curtain as early as possible under the premise of temperature.
After the water and fertilizer management is planted until the beginning of the second year and the beginning of February, during this period, the watering should be irrigated twice with 1500 times of transplanting spirit, and each time the planting liquid is 0.2 kg. After the second year of February, as the sunshine time prolonged, the temperature increased, the plant growth rate increased, and the water and fertilizer management was strengthened. Every 15 days or so, the micro-spraying method combined with watering and fertilization was applied to the Nopfeng compound. Each time the fertilizer is 8 kg, it is applied with water until it is applied twice in the whole growth period, 15 kg each time. In March, combined with fertilization, water is poured every 10 days. The whole growth period is alternately applied by Manica and Knopfun. 8 times, in April, in the case of increasing the amount of air release, the method of clear irrigation is applied every 7 days, about 500 kg each time. By adopting the above fertilization method, the yield and quality of the melon are obviously improved. . Wu Xuemin
PS Sheet is commonly known as "organic board", chemical name Polystyene polystyrene, density 1.02 ~ 1.08 is a thermoplastic, transparency is higher (light transmittance is second only to organic glass), has excellent electrical insulation, high frequency insulation Especially good, the quality is brittle, the impact resistance, weather resistance and aging resistance are inferior to plexiglass, the mechanical processing properties and thermal processing properties are not as good as plexiglass, it can resist general chemical corrosion, the chemical properties are stable, the hardness is similar to plexiglass, The water absorption rate and thermal expansion coefficient are less than plexiglass, and the price is cheaper than plexiglass.
PS Sheet is made of polystyrene as the main raw material, extruded, can be freely colored, odorless, tasteless and non-toxic, does not cause fungus growth, has the advantages of rigidity, insulation, good printability, etc. It is mainly used for packaging, container equipment, Daily decoration, general electrical appliances and construction industries.
Polystyrene Sheet ( PS Plate ) is made by extrusion, main raw material is polystyrene granule. Mainly used for packaging, container equipment, General electrical and construction and other industries.
PS polystyrene decorative board is a high-molecular organic board extruded by polystyrene granule molding compound on the extruder unit.
