Meteorological environment of brew grapes in edge-desert and their response to ecological environment

Developmental procedures and corresponding meteorological environments of 7 brew grape cultivars (Meiluzhe, Pinlizhu,etc)in edge-desert were investigated. Results show that brew grape key fruit development period is from the first ten days of June to the first ten days of August and key sugar accumulation period is August.Important factors that affect grape sugar content include accumulated temperature,accumulated amplitude of diurnal temperature variation, and relative humidity. Analysis of soil water variation with time and soil depth indicates that grape average water consumption in the entire growth period is 423.2mm. Grape consumes the least water from budding to leaf growth, and the most water from blossom to maturity.From leaf growth to blossom and from maturity to leaf shedding,grape consumes similar amounts of water.Brew grapes in edge-desert consume less water than other crops and bring more benefits by increasing farmers’income without reducing cropland area.
