葡光互补对吐鲁番‘无核白’葡萄生长的影响

Influence of Grape and Photovoltaic Panels Complementation Mode on Growth of ‘Thompson Seedless’ Grape in Turpan

以吐鲁番7a生‘无核白’为试验材料,研究不同光伏板密度对‘无核白’生长动态的影响,旨在找到合适的光伏板密度,为葡光互补新型栽培模式的推广提供科学依据。结果显示:随着光伏板密度的增加,‘无核白’葡萄的芽、枝叶和果实的生长均表现出先升高后降低的变化趋势;轻度遮阴条件下(C1),‘无核白’葡萄的芽、枝叶和果实的生长发育均优于全光照(CK);轻度遮阴有利于缓解夏季高温强光对葡萄生长发育的危害,但过度遮阴会产生负面影响。所以综合考量不同密度光伏板下葡萄的芽、枝叶和果实生长趋势变化情况,建议在吐鲁番地区推广葡光互补栽培模式时,选择光伏板间隔1.5m为宜。

In order to find a suitable density of photovoltaic panels, and provide scientific basis for the further promotion new cultivation model of grape-photovoltaic panels complementation, the 7-year-old ‘Thompson Seedless’ grapes in Turpan were used as test materials to identify the influence of photovoltaic panels density on growth dynamics of ‘Thompson Seedless’ grapes in Turpan. The results showed that the growth of buds, new shoots, leaves and berries of ‘Thompson Seedless’ grapes had a trend of increasing first and then decreasing with the increase of the density of photovoltaic panels;the growth and development of buds, new shoots, leaves and berries of ‘Thompson Seedless’ grape were better under less light shading condition(C1) than under full light condition(CK);light shading is beneficial to alleviate the damage of high temperature and strong light in summer on the growth and development of grapes, but excessive shading will result in a negative impact. Therefore, based on the comprehensive consideration of grape quality and photovoltaic panel power generation benefits, during the promotion of new grape-photovoltaic panels complementation cultivation model, photovoltaic panel spacing is recommended 1.5 m in Turpan.
