Influence of Plastic Covering on the Microclimate in Vineyards in the São Francisco River Valley Region
Abstract Data from field experiments conducted in table grape vineyards variety of Festival in Petrolina-PE in the period from September 19 to October 12, 2010 were used to evaluate the influence of plastic cover on microclimate conditions of vineyards in São Francisco River Valley region.

description | Abstract Data from field experiments conducted in table grape vineyards variety of Festival in Petrolina-PE in the period from September 19 to October 12, 2010 were used to evaluate the influence of plastic cover on microclimate conditions of vineyards in São Francisco River Valley region. Three treatments were studied: canopies without plastic cover (WC); with plastic cover positioned at 50 cm (PC50), and at 100 cm (PC100) above canopy. The results indicate that the plastic cover prevented the passage of about 40% of the global and net radiation, retained the relative humidity inside the canopy, generated an increase of air temperature and marked reduction in wind speed over the canopy of treatment PC50. However, treatment PC100 had a higher incidence of short wavelength and net radiation under canopy (on the berries) than WC and PC50 treatments, resulting in more favorable weather conditions, providing about 40% greater productivity in this treatment. Therefore, the vineyard with plastic cover placed at 100 cm above canopy represents a more suitable alternative to the climatic conditions of the region of the São Francisco River Valley.
Resumo Dados de experimento de campo conduzido em parreirais de uva de mesa da variedade Festival em Petrolina-PE, no período de 19 de setembro a 12 de outubro de 2010 foram usados para avaliar a influência da cobertura plástica sobre as condições microclimáticas de parreirais na Região do Vale do Rio São Francisco. Estudaram-se três tratamentos: dosséis sem cobertura plástica (WC); com cobertura plástica posicionada a 50 cm de altura (PC50); e a 100 cm de altura (PC100). Os resultados indicaram que a cobertura plástica impediu a passagem de cerca de 40% da radiação global, reteve a umidade relativa no interior dos dosséis, gerou aumento de temperatura do ar e acentuada redução da velocidade do vento sobre o dossel PC50. No entanto, o tratamento PC100 teve maior incidência de onda curta e saldo de radiação sob dossel (sobre as bagas) do que os tratamentos WC e PC50, resultando em condições climáticas mais favoráveis, proporcionando cerca de 40% a mais de produtividade neste tratamento. Portanto, o parreiral com a cobertura plástica posicionada a 100 cm de altura representa uma alternativa mais adequada às condições climáticas da região do Vale do São Francisco. |
