摘要
为探究光伏环境下不同大豆品种的苗期适宜性,对日光温室内光伏板下31个大豆品种(浙江省主推品种)进行适宜性评价(以无光伏板作为对照),分析光伏设施荫蔽对大豆苗期生长的影响,并通过耐荫性评价模型和聚类分析综合判断各大豆品种对光伏环境的适应能力。在移栽后30 d,测定大豆苗期的20个生长形态、生物量及生理指标,计算各性状的耐荫系数,并通过主成分分析、隶属函数法及聚类分析,把大豆的多个性状指标转化为6个新的综合且各自独立的指标,其权重分别为0.251、0.229、0.170、0.138、0.126、0.115。根据综合评价值(D值),光伏板下31个大豆品种苗期适宜性可分为强、良好、差3类,其中:9个品种为适宜性强,分别为八月拔、东山白马豆、兰溪大青豆、嘉丰绿皮豆、沙心豆、特泛豆1号、浙鲜9号、浙鲜12号、浙春14号;12个品种为适宜性良好;10个品种为适宜性差。本研究为农光互补体系下保障大豆的生长和产量提供了理论参考和适宜性品种。
In order to investigate the suitability of different soybean varieties at seedling stage under a photovoltaic environment,the suitability evaluation of 31 soybean varieties(mainly promoted varieties in Zhejiang Province)was conducted under photovoltaic panels in a solar greenhouse(taking no photovoltaic panels as a control),and the effects of photovoltaic shading on soybean seedling growth were analyzed.The adaptability of soybean varieties to photovoltaic environments was comprehensively evaluated by shade tolerance evaluation model and cluster analysis.After 30 days of transplantation,20 morphological,physiological and biomass indexes of soybeans were measured,and the shade tolerance coefficient of each trait was calculated.Through principal component analysis,membership function method and cluster analysis,the multiple traits of soybeans were transformed into six new comprehensive and independent indexes with weights of 0.251,0.229,0.170,0.138,0.126,and 0.115.According to the comprehensive evaluation value(D value),31 soybean varieties were divided into three types:9 materials were highly suitable,and 12 materials were moderately suitable,and 10 materials were poorly suitable.The highly suitable varieties included Bayueba,Dongshanbaimadou,Lanxidaqingdou,Jiafenglüpidou,Shaxindou,Tefandou 1,Zhexian 9,Zhexian 12,and Zhechun 14.The study provides a theoretical reference and suitable varieties for ensuring soybean growth and yield under an agriculture-light complementary system.
