【摘要】 以甘薯普薯32为试验材料，研究不同叶面肥对甘薯普薯32农艺性状、光合性状、产量和品质性状的影响，并对数据进行相关性分析和主成分综合评价。结果表明：不同叶面肥对普薯32的生长性状和光合性状影响不同，相关性分析表明产量与各性状呈正相关，其中产量与商品率和干物质率呈显著正相关；对不同叶面肥对普薯32的各性状进行主成分综合评价，希沃丰大量元素水溶肥和薯墩儿氨基酸水溶肥分别排名第1和第2,这两种叶面肥有利于甘薯普薯32生长，产量的提高和品质的提升，是适合普薯32的叶面肥。更多还原

【Abstract】 In order to investigate the effects of different foliar fertilizers on the growth of sweet potatoes, sweet potato ‘Pushu 32’ was used as the experimental material to explore the effects of different foliar fertilizers on the agronomic, photosynthetic, yield, and quality traits. The data underwent correlation analysis and principal component comprehensive evaluation. The results showed that different foliar fertilizers had different effects on the growth and photosynthetic traits of ‘Pushu 32’. Correlation analysis showed a positive correlation between yield and various traits, with a significant positive correlation between yield and commodity rate and dry matter rate; A principal component comprehensive evaluation was conducted on the effects of different foliar fertilizers on the various traits of sweet potato ‘Pushu 32’. Large element water-soluble fertilizer of ‘Xiwofeng’ and Shuduner amino acid water-soluble fertilizer ranked first and second, respectively. These two types of foliar fertilizers are beneficial for the growth, yield, and quality of sweet potato‘Pushu 32’, making them suitable foliar fertilizers for sweet potato ‘Pushu 32’.更多还原
