Prolonging cultivation facility 4-year-old Red Globe grapes a 3750m ~ 3/hm ~ 2 (A), 3000m ~ 3/hm ~ 2 (B), 2250 m ~ 3/hm ~ 2 (C) and 1500 m, ~~ 3/hm ~ 2 (D) four different irrigation treatments, control of conventional irrigation (3300 m ~ 3/hm ~ 2) to study the amount of different irrigation facilities delayed cultivation Red Globe grapes orchard soil temperature, humidity, the impact of of grape physiological and biochemical characteristics and fruit quality, in order to provide a theoretical basis for delayed cultivation Red Globe grapes Cold Plateau district facilities for water-saving irrigation. The main findings are as follows: 1. Various irrigation treatments 07:00,13:00 and 19:00 vineyards months, the average temperature in June and September showed a downward trend, from September to December, slightly fluctuating. The average temperature in June 7 :: 00 CK gt; gt; D C gt; A gt; B, September CK gt; A gt; C gt; D gt; B, A, B, C, D and CK annual average The ground temperature was 12.19 ° C, 11.38 ° C, 11.39 ° C, 11.79 ° C, 13.07 ° C, respectively. 13:00 June monthly average ground temperature C gt; gt; CK gt; A gt; B, in September A gt; CK gt; D gt; C gt; B, A, B, C, D and CK years The average ground temperature were 15.44 ° C, 14.36 ° C, 14.74 ° C, 15.81 ° C, 15.57 ° C, respectively. 19:00 pm June average temperature C gt; CK gt; D gt; A gt; B, September A gt; CK gt; D gt; C gt; B, A, B, C, D, and CK annual average ground temperature were 15.17 ℃, 14.00 ℃, 14.42 ℃, 14.98 ℃, 15.34 ℃. The average temperature in June day in each treatment was C gt; CK gt; D gt; A gt; B. The average geothermal September day was CK gt; A gt; D gt; C gt; B 2 different irrigation grape orchards average soil moisture in 0-10cm layer A, B, C, D and CK were 21.65%, 20.65%, 19.64%, 18.84%, 21.01%, 10 to 20cm soil layer A, B , C, D, and CK were 23.26%, 21.97%, 21.19%, 20.33%, 22.49%, 20 to 40cm soil layer A, B, C, D and CK were 25.38%, 23.97%, 23.28%, 22.36% , 24.68%. A treatment of the different soil layers average soil moisture of the largest, followed by CK, B, C and D; A, B, C, and CK differences not significant differences in D and CK significantly. With the reduction of irrigation amount each growth stage Grape Leaves SOD, POD and CAT activity gradually increased MDA, proline content increased, the soluble protein content decreases gradually, gradually increased water stress suffered by the grape. Grape leaf total chlorophyll showed a decreasing trend after the first increase, irrigation reduction in the amount of mild water stress can stimulate grape chlorophyll synthesis, promotes plant plant carbohydrate synthesis, is conducive to the increase in production. B treated ear weight 6.06% higher than CK, berry weight 6.00% higher than that of CK, the berry transverse diameter and the berry longitudinal diameter respectively 0.50% and 1.04% higher than CK, soluble solids content than CK 2.79% higher titratable acid content is 10.54% lower than that of CK. B treatment effective water-saving at the same time, and can effectively improve grape quality, optimal irrigation amount indicators Red Globe grape cultivation Tianzhu and similar district facilities delayed.
