FLORES ORTEGA, Adrián et al. Study of strategies for climate management in low-tech greenhouses in hot climates. Rev. Mex. Cienc. Agríc [online]. 2018, vol.9, n.spe21, pp.4383-4394. ISSN 2007-0934. https://doi.org/10.29312/remexca.v0i21.1527.
In the present work, the study of the effect of shading and ventilation as strategies for microclimate management in low technology greenhouses in the Irapuato region of Guanajuato is exposed. By means of the measurements of the climatic variables of global solar radiation, temperature and humidity of the air, the transmittance of the greenhouses was determined, which were of τ= 0.56 for the greenhouse without liming and τ= 0.26 and τ= 0.14 for the shaded greenhouse by liming and thermal meshes. The rate of air renewal was determined and it turned out that an exchange of N= 59.4 h-1 is adequate for the regulation of temperature. It was concluded that shading has little influence on the behavior of the temperature and humidity of the air inside, while the overhead and lateral ventilation is decisive for the regulation of the microclimate.
