摘要: |
为探讨新型的冬季保温被覆盖对贺兰山东麓葡萄植株越冬生理代谢的影响,以贺兰山东麓青铜峡产区的‘霞多丽’‘玫瑰香’葡萄为研究对象,以冬季埋土作为对照,分别对土壤温度、植株存活率、枝条含水量、植株抗寒指标、内源激素含量和蔗糖代谢指标进行测定。结果表明:保温被覆盖对维持土壤温度具有明显作用,保温被覆盖处理下土壤温度介于-0.8~2.9 ℃,保温被覆盖处理葡萄植株存活率、游离脯氨酸含量、超氧化物歧化酶活性、蔗糖磷酸合成酶活性、蔗糖转化酶活性、淀粉含量和蔗糖含量均低于埋土处理,保温被覆盖处理枝条含水量、丙二醛、赤霉素和吲哚丙酸含量均高于埋土处理。综上,采用保温被覆盖措施可以保护葡萄安全越冬,以达到防寒效果,且与传统的埋土防寒相比具有省时、省力和节约成本等优势,因此保温被覆盖葡萄植株的越冬方式在贺兰山东麓产区有一定的推广使用价值。 |

Abstract: |
To explore the effects of new winter thermal insulation coverage on the physiology and metabolism of overwintering grapevines, ‘Chardonnay’and‘Midknight Beauty’varieties from the Qingtongxia region in the eastern foothills of the Helan Mountain was taken as the research objects. Vines that were buried under the soil during the winter were used as the control. The soil temperature, plant survival rate, water content, cold resistance indicators, content of endogenous hormones and the sucrose metabolism of the branches were measured. The results of this study showed as follows: The thermal insulation covering had a significant effect on maintaining the soil temperature, which ranged from -0.8 ℃ to 2.9 ℃ under the thermal insulation covering treatment. The survival rate of the grapevines, their contents of free proline, starch, and sucrose, the enzyme activities of superoxide dismutase, sucrose phosphoribosyl synthase, and sucrose converting enzyme of the vines covered with thermal insulation were lower than those buried. The contents of water, malondialdehyde, gibberellin and indole propionic acid in the branches were all higher than those buried in the soil. On the whole, the use of insulating blankets to cover the grapes safely protected them over the winter. Compared with the traditional method of buried soil to overwinter the vines, the wintering method created in this study also saved time, labor and money. Therefore, the wintering method of thermal insulation and covering grape plants has certain promotional and usage value in the eastern foothills of Helan Mountain. |
