Experimental Fabrication and Design for the Transmissivity of Polyethylene in Agriculture ในงานเกษตรกรรม
Abstract
The objective of this research was to design and construct an experiment in order to determine the light transmittance of polyethylene in agriculture using 200 mm thicknesses. The Warm White LED lamp (5 W) was used through fiber optics connected to spectrometer at the wavelength range between 410 - 575 nm. According to the results, the transmittance value of each polyethylene was consistent with the physical properties of the polyethylene film. When this experimental set was used to measure the transmittance of polyethylene at different thicknesses (In microns). The results showed that the experimental set had the potential to distinguish polyethylene at different thicknesses and in accordance with the basic theory of transmission as well. The results revealed that this experimental set had the potential to distinguish polyethylene at different thicknesses. Therefore, this transmittance set is sufficiently effective enough to measure the transmittance of polyethylene. In order to be informed of the decision to use polyethylene, cover the soil or cover crops in agriculture.
