Effect of temperature on phenophase of “xiahei” grape

A contrast test between early forcing cultivation (early forcing area) and rain shelter cultivation (control area) was conducted from January to March of 2012 and 2013 respectively, the results showed that through the temperature regulation in greenhouse and under the prerequisite ensuring the reasonable illumination and humidity, adopting the early forcing cultivation “xiahei” grapes promoting could achieve the effective accumulated temperature required in various phenophases and advance each phenophase to varying degrees, and maturing date in 2012 and 2013 was earlier by 21d and 32d respectively to compare with control.
