施肥策略对大果山楂果实产量及品质的影响

Effects of fertilization strategy on Malus domeri (Bois) Chev. yield and quality

  • 摘要: 科学施肥是产业链生产重要举措,直接影响大果山楂生长、产量和品质。以靖西大果山楂为对象,以不施肥为对照,开展中微量元素肥、生物菌有机肥及袋控释掺混肥料施用对比试验,分析评判不同施肥策略效果,为果农科学施肥提供依据。方差分析表明,3个施肥处理大果山楂果实产量、总三萜、亮度值显著提升,裂果率显著降低,果实氮含量显著提高;3个施肥处理大果山楂果实产量及品质指标与对照处理的差异表现水平不一。熵权DTOPSIS法分析表明,生物菌有机肥处理综合效果最佳。Spearman相关系数综合分析表明,可溶性固形物含量、氮含量、钙含量、磷含量和镁含量间普遍存在极显著正相关;裂果率与钾含量呈极显著负相关。施用中微量元素肥、生物菌有机肥、袋控释掺混肥料均有效提升大果山楂果实品质及产量,以施用生物菌有机肥1320 kg/hm2效果最佳。

     

    Abstract: Scientific fertilization is an important measure in industrial chain production, directly affecting Malus domeri(Bois)Chev. growth, yield, and quality.Jingxi Malus domeri(Bois)Chev. was used as object, with no fertilization as control.A comparative experiment treated single application of medium trace element fertilizer, bio-bacterial organic fertilizer, and bag-controlled release fertilizer, to evaluate effects of different fertilization strategies, aiming to provide scientific fertilization guidelines for fruit farmers.Analysis of variance showed that three fertilization treatments significantly increased Malus domeri(Bois)Chev. yield, total triterpenoids, and brightness value, while fruit cracking rate was significantly decreased, and fruit nitrogen content was significantly increased.Differences in yield and quality indexes between three treatments and control treatment.Entropy weight DTOPSIS method analysis revealed that bio-bacteria organic fertilizer treatment achieved the best comprehensive effects.Spearman correlation coefficient comprehensive analysis indicated highly significant positive correlation among soluble solids content, nitrogen content, calcium content, phosphorus content, and magnesium content.Fruit cracking rate was negatively correlated with potassium content.Malus domeri(Bois)Chev. quality and yield were effectively improved by applying medium trace element fertilizer, bio-bacterial organic fertilizer, and bag-controlled release fertilizer.Among them, applying 1320 kg/hm2 bio-bacterial organic fertilizer had the best effect.
