Resumo: | This project was developed in the Faculty of Engineering - Unesp, Campus of Ilha Solteira, in the municipality of Ilha Solteira – São Paulo State. We studied the environmental behavior under two conditions of protected environment, with plastic covering the soil and bare soil. It was evaluated the quinquidial averages, averages values, maximum and minimum daily temperature and relative humidity; quinquidial averages of the daily average values of deficiency of saturation of water vapor; the density of total daily flow of radiation; from transmission to radiation in each shelter and the linear regressions to estimate the total daily radiation inside the shelter, according to the daily total radiation in field open. The protected environment reduced, in relation to the open field, the density of flow of solar radiation, with higher intensity in the shelter covered with thermal plastic film light-diffuser. The greatest effect of shelters occurred on the maximum temperature, with higher values the greenhouse covered with a conventional polyethylene film. There were no differences for air relative humidity between greenhouses. The black plastic mulching increased the soil temperature at 6 and 12 cm depth. |

Estudou-se o comportamento do ambiente em duas condições de ambiente protegido, com cobertura plástica do solo e em solo nu. Avaliaram-se as médias, por quinquídio, dos valores médios, máximos e mínimos diários de temperatura e umidade relativa do ar. As médias, por quinquídio, dos: valores médios diários de déficit de saturação de vapor d’água; dos totais diários de densidade de fluxo de radiação; das transmitâncias à radiação, em cada abrigo e as regressões lineares para estimativa dos totais diários de radiação no interior dos abrigos, em função do total diário de radiação em campo aberto. O ambiente protegido reduziu em relação ao campo aberto a densidade de fluxo de radiação solar, com maior intensidade, no abrigo coberto com filme plástico térmico difusor de luz. O maior efeito dos abrigos ocorreu sobre as temperaturas máximas, tendo maiores valores a estufa coberta com filme de polietileno convencional. Não ocorreram diferenças para umidade relativa do ar entre as estufas. O mulching plástico preto aumentou a temperatura do solo a 6 e 12 cm de profundidade.Universidade Estadual de Maringá2011-06-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/278410.4025/actasciagron.v33i3.2784Acta Scientiarum.
