Abstract:: ‘Red globe’ grape was used as test material,studying the influence of the rain shelter cultivation and open cultivation on grape downy mildew,gray mold,anthrax,white rot incidence and the rate of rotten fruit,fruit quality and economic benefit,measuring the light intensity and analyzing the cost of shed frame materials with different price and lifetime.The results showed that rain shelter cultivation sharply reduced the number of pesticide and dose,reduced the pesticide residue,improved fruit quality and reduced the rotten fruit rate,thus increasing the economic benefit.Rain shelter cultivation was higher 55.8% profits than open cultivation average per 667 m2.The rain shelter cultivation could significantly reduced the incidence of the grape downy mildew,white rot,anthrax,gray mold.Especially in preventing and controlling downy mildew.it concluded that the incidence of downy mildew under rain shelter cultivation was lower 91.4% than the open cultivation.But the rain shelter cultivation reduced the light intensity in a certain degree.By four different rain shelter structures and material analysis,it concluded that all wire type had the characteristics of the lowest cost and life expectancy,it was ideal shape material of grapes rain shelter cultivation in Shaanxi Guanzhong region.
