不同农艺措施对霞多丽葡萄叶幕微气候的影响OA北大核心CSTPCD

[Objective]To study the leaf curtain microclimate of Chardonnay grapes before and after the color transition period by two different agronomic measures,namely grass planting and shade,in order to de-termine the influence of different measures on the grape in the hope of providing scientific basis for improving fruit quality.[Methods]Taking wine grape'Chardonnay'as the research object under the same conditions for 2 years,the light,temperature,humidity and soil water content of the leaf curtain of the grape before and after the color transition period were comprehensively studied by using the two measures of planting alfalfa in row and black sunshade net.Finally,the best agronomic measures were determined based on post-harvest physi-cal and chemical indexes and sensory evaluation.[Results]Both grass and shade treatment could improve the microclimate of the curtain,and the quality of the products was improved after raw materials were collected,a-mong which shade treatment had a significant effect.[Conclusion]'Chardonnay'grape has cooling and humid-ifying effect on leaf curtain microclimate by adopting grass and shade measures,thus playing a role in impro-ving fruit quality.
