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
Effects of winter thermal insulation cover on the overwintering physiological metabolism of grapevines in the eastern foothills of Helan Mountain
摘要
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.关键词
