Study On The Fruiting Habit And Economic Characters Of Vitis Vinifera L. Cv. Cabernet Sauvignon In Manas Regions

Based on wine grape wine grape production areas in Xinxiang Manas cabernet sauvignon as the material, the varieties of botany characteristics observed in 2008, economic characters, resistance analysis, berry quality analysis, etc., aims to explore the comprehensive performance of cabernet sauvignon in Manas area, for the region’s wine grape cultivation and wine production to provide certain theoretical basis.Experimental results are as follows:based on the wine grape cabernet sauvignon wine grape production areas in Xinxiang Manas area as the material, the varieties of botany characteristics observed in 2008, economic characters, resistance analysis, berry quality analysis, etc., aims to explore the comprehensive performance of cabernet sauvignon in Manas area, for the region’s wine grape cultivation and wine production to provide certain theoretical basis. The experimental results are as follows:1. Budding period for April 30,2008, on June 4, in full bloom, is 7 to 10 d behind the eastern region. On July 25, began to turn, turn the color of 18 d, turn color uniformity, color transfer process is the same, turn color fast. On September 19, the grapes fully mature, mature time 38 d.In 2008,’cabernet sauvignon grapes in Manas regions of growth period 158 days.2. Throughout the year, the Manas regions, sunshine hours reduced after rising first, between April 10 month more than 8 hours. Among them, the bud-boron and boron-turn began to two periods of color, sunshine time is more than 500 hours.Manas regions is extremely low, average relative humidity throughout the year, the average relative humidity below 10%, presents the rainfall is small and concentrated rainfall, the present situation of the air dry evaporate easily. In October 4-in particular, the average relative humidity below 5%.In each growth period of grape fruits, air humidity difference is small, all maintained at 4%.3. Throughout the period of’cabernet sauvignon grapes, there are 28 day minimum temperature above 20 DHS C, at the same time there are 24 in the highest temperature is higher than 30 DHS C, sun turn the occurrence of extreme weather is focused on the color term and berries mature period. Temperature difference between day and night difference during the whole growth period, to maintain the DHS 11～13 C, highest maturity of berries, DHS 12.75 C.4. Engraftment in Manas area ’cabernet sauvignon grape grain, grain shape is given priority to with conical, account for more than 99% of all ear, shoulder, unilateral or bilateral disambiguation ear compactness between closely and loose medium, the average grain weight 152 g, with an average of 134 fruit grains/ear, grain is relatively small. Fruit grain of longitudinal diameter 1.21 cm, diameter 1.04 cm, fruit grain of small volume, the skin is dark purple, skin thickness, fruit powder, and thick flesh capsule.5. In Manas regions, turn ’cabernet sauvignon fruit color to commercial harvest time this time period, the content of total sugar keeps rising trend. After fully mature fruit, the accumulation of sugar is still increasing, until commercial harvest time, up to 218 g/L.At the same time, the content of total acid showed a trend of falling, in a completely mature, finally decline leveling off, fell to 7.9 g/L, no significant change.6. In last year’s winter pruning, ’cabernet sauvignon’ leave bud number for 48/plant, plant growth potential and the following year body-to keep germination rate is moderate, and the germination rate is greater than 60%, strong percentage is more than 70%.7. In the same plot, the ’cabernet sauvignon grape production of the commercial harvest time for three consecutive years investigation and survey results are shown in figure 3.3.Three years in a row, the same plot ’cabernet sauvignon grape yield is 17750+ 520 kg/hm3 respectively,17750-600 kg/hm3,21675-580 kg/hm3, annual growth rate of 10.8% and 11.5% respectively, the yield stability is good.The above results show that the cabernet sauvignon grapes in Manas area excellent comprehensive properties, production stability, advice in the Manas area wine grape base construction intensify popularization. The cultivation should pay attention to prevent spring frost damage in the region.
