光伏板对吐鲁番‘无核白’葡萄叶幕微气候、叶片质量及果实品质的影响

以吐鲁番7年生‘无核白’为试验材料,研究不同密度光伏板对‘无核白’叶幕微气候、叶片质量以及果实品质的影响,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。结果表明:随着光伏板密度的增大,叶幕空气温度降低,空气相对湿度增大,光照强度显著降低。‘无核白’葡萄叶片质量、果实品质随着光伏板密度的增大呈现出先上升后下降的变化趋势,中度遮阴条件下,‘无核白’叶片的纵、横径,叶绿素含量和果实中可溶性固形物含量均表现最佳。在吐鲁番地区采用光伏板遮阴对‘无核白’葡萄叶幕微气候有显著影响,适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。在吐鲁番地区推广葡光互补栽培模式时,建议选择光伏板的间隔为1.0 m。

Influence of cultivation mode of complementation of grape and photovoltaic panels on canopy microclimate,leaf quality and berry quality of 'Thompson Seedless' in Turpan

In order to find a suitable density of photovoltaic panels,and provide scientific basis for the promotion of grape-photovoltaic panels complementation new cultivation model,the 7 years old of’Thompson Seedless’in Turpan were used as test materials.Research the influence of different density photovoltaic panels on canopy microclimate,leaf quality and berry quality of’Thompson Seedless’.The results showed that with the increase of the density of photovoltaic panels,the air temperature of the canopy were lowered,the relative humidity were increased,and the light intensity were significantly reduced.The leaf and berry quality of’Thompson Seedless’showed a trend of increasing first and then decreasing;Under moderate shading conditions,the leaf length and leaf width,chlorophyll content and berry soluble solids of’Thompson Seedless’were the best.The use of photovoltaic panels in the Turpan area has a significant impact on the canopy microclimate of’Thompson Seedless’.Moderate shading is beneficial to alleviate the dangers of high temperature and strong light in summer on the growth and development of grapes,but excessive shading will have a negative impact.It is recommended to promote the grape-photovoltaic panels complementation new cultivation model with a photovoltaic panel spacing of 1.0 m in Turpan.
