摘　　要：为明确不同微藻有机水溶肥料对设施番茄生长、产量及品质的影响,通过主成分分析和综合评价得分,综合评价不同微藻有机水溶肥料的肥料效应,为番茄产量、品质综合评价提供分析方法和实现番茄高产、优质提供理论依据。选择了3种不同的微藻有机水溶肥料,通过2年的田间试验探索了不同微藻有机水溶肥料对番茄产量及品质的提升效果。试验结果表明:(1)施用微藻有机水溶肥料番茄的产量显著高于清水对照处理,在等量常规施肥的条件下,施用3种微藻有机水溶肥料(Competitor、Algafert、Levoamin)的处理单果重均显著增加,产量分别提高了4.87、6.86、5.46 t/hm^(2);(2)与常规施肥对照和清水对照相比,施用3种微藻有机水溶肥料的硝酸盐和有机酸含量显著降低,可溶性固形物和维生素C的含量显著增加;(3)从主成分综合得分分析,施用Algafert的处理得分最高,其次是Levoamin,最低为Competitor。综合考虑番茄的株高、茎粗、产量、品质等因素,番茄最佳施用效果的微藻有机水溶肥料为Algafert。The objective was to investigate the effects of different microalgae organic fertilizers on the growth,yield and quality of tomato.Through the principal components analysis and evaluation scores of effects of different micro algae organic water-soluble fertilizers,an analytical method and theoretical basis were provided to evaluate the quality and achieve high yield and quality.Three microalgae organic water-soluble fertilizers were selected,and explored the improvement effect of different microalgae organic water-soluble fertilizers on tomato yield and quality through a 2-year of field experiment.The results showed that:(1)The yield of tomato treated with microalgae organic water-soluble fertilizer was significantly higher than that of the water control treatment.Under the same amount of conventional fertilization conditions,the single fruit weight of the treatment treated with three types of microalgae organic water-soluble fertilizers(Competitor,Algafert,Levoamin)was significantly increased,and the yield was increased by 4.87,6.86,5.46 t/hm^(2),respectively.(2)Compared with conventional fertilization control and clear water control,the nitrate and organic acid content of the three microalgae organic water-soluble fertilizers were significantly decreased,while the content of soluble solids and vitamin C were significantly increased.(3)From the analysis of principal component comprehensive scores,the treatment using Algafert scored the highest,followed by Levoamin and Competitor.Taking into account factors such as plant height,stem diameter,yield and quality of tomatoes,the microalgae organic water-soluble with the best application effect on tomatoes was Algafert.
