The Study Of Difference Coverage Effect On Cabernet Sauvignon Grape Over Wintering

Take "Cabernet sauvignon" as materials, set covering soil, polystyrene insulation and fiber blanket +covering soil as treatments. By monitoring the soil temperature and moisture content near the dendrites and roots during winter and investigating grape bud rate, branching ratio, and fruit rate in the following year, which helped measure the physiological and biochemical indexes of grape vines and roots as well as tested the mainly quality of grapes.The temperatures of polystyrene insulation, fiber blanket+covering soil were relatively high. The roots and tendrils of fiber blanket+ covering soil had a highest temperature. Threat low temperature zone of the fiber blanket+ covering soil was 0 h. It reduced 185.5h Compared with casing. Polystyrene insulation was reduced to 110h Compared with casing. Low threat area which was grape Root casing reached 267h. The remaining two treatments was 0 h.Physiological parameters of dendrites indicate that:The ratio of bound water and free water in January and February, fiber blanket+covering soil> polystyrene insulation> casing, and electrolyte leakage rate was negatively correlated with temperature. Electrolyte leakage rate was casing> polystyrene insulation>fiber blanket+ covering soil in January 1,2015; The MDA that fiber blanket+ covering soil content of dendrite was almost unchanged. The MDA of covering soil’s Dendrite increased 0.0021mol/g after winter. Polystyrene insulation increased by 0.0053mol/g; The dendrite proline of the treatment of fiber blanket+ covering soil compared with polystyrene insulation, covering soil is increased 0.0008μg/g,0.0011μg/g in January.Physiological parameters of roots show that:0-20cm soil layer roots prone to frost damage. Covering soil, polystyrene insulation, and fiber blanket+ covering soil covering soil electrolyte leakage rates were 74.7%、67.3%、58%; The layer of root MDA content, polystyrene insulation and fiber blanket +casing soil opposite casing soil were reduced by 0.00087umol/g,0.00097umol/g; Covering soil roots free proline content is 0.006133μg/g, fiber blanket+covering soil relative increase 0.000334μg/g compared with casing soil.Germination rate, branching ratio and Results coefficient, fiber blanket+ covering soil and polystyrene insulation covered by wintering manner which was invested the following year had slightly improved compared with casing soil. The main quality measurement of fruit as well as the fiber blanket +covering soils single fruit quality was processing up to 1.35g, increased 0.16g compared with the casing soil, increased 0.13g compared with polystyrene insulation. Polystyrene insulation had the highest total soluble sugar content, Followed by chemical fiber blanket+ covering soil. Fiber blanket+ covering soil improved 1.66% compared with casing soil. The total acid content fiber blanket+ covering soil was up to 8.09%. It was significantly higher than the casing soil treatment, However, the total acid polystyrene insulation was slightly below than the casing soil process.The insulation of material could be reduced during the winter, Dry fiber blanket+ covering soil thermal resistance was up to 2.268 W·m-2K-1.It was Higher than the casing treatment 0.019. The thermal resistance of the wet chemical fiber carpet turned out to be only 6.5%.Fiber blanket+ covering soil turns out to the best method to help grapes casing over the winter. By adopting this method, grapes grew well the following year. The Materials that used had the advantage of economical and durable. It deserved to be introduced in the Helan Mountain area.
