摘要
探究叶面喷施有机硒对无核黄皮果实硒含量以及果实品质的影响,以期为生产富硒无核黄皮提供一定参考依据。以无核黄皮为材料,选用有机硒肥为硒源,设置不同浓度有机硒处理,分别为1、10、50、100、500 mg/L,以喷施等量的纳米硒营养液、清水为对照。结果表明,叶面喷施有机硒可提高无核黄皮果皮和全果中的硒含量,并随有机硒浓度的升高而显著增加。喷施有机硒可有效改善果皮的色差值,其中以100 mg/L处理效果最佳。此外,叶面喷施有机硒也可显著提高无核黄皮果实中可溶性固形物、可滴定酸、维生素C含量。通过主成分分析进行综合评价发现,喷施有机硒处理得分均高于清水对照,且喷施不同浓度有机硒处理得分由高到低依次为100 mg/L>500 mg/L>50 mg/L>10 mg/L>1 mg/L。因此,综合分析结果表明,叶面喷施100 mg/L有机硒对增加无核黄皮果实硒含量,改善果面色泽和提升果实内在品质的效果最佳。
This study explored the effects of foliar spraying of organic selenium fertilizer on the selenium content and overall quality of seedless wampee with the aim to providing a reference and theoretical basis for the production of selenium-rich seedless wampee.Seedless wampee was used as the experimental material,selected organic selenium fertilizer with the concentration of 1 mg/L,10 mg/L,50 mg/L,100 mg/L,500 mg/L as the treatment groups,and equal amounts of water and nano-selenium nutrient solution spraying treatment as the negative and postitive control group respectively.The results showed that spraying organic selenium fertilizer on the leaves could increase the selenium content in the seedless wampee pericarp and whole fruit,and the effects was significant with the increase of selenium concentration.Spraying organic selenium can effectively improve the color difference value of the peel,with the best effect at 100 mg/L.In addition,foliar spraying of organic selenium can also significantly increase the content of soluble solids,titratable acid,and vitamin C content in seedless wampee fruits.The comprehensive evaluation scores obtained through principal component analysis showed that the scores of the organic selenium spraying treatment groups were higher than those of the water treatment group,and the scores of the organic selenium spraying treatment groups with different concentrations were ranked from high to low as follows:100 mg/L>500mg/L>50 mg/L>10 mg/L>1 mg/L.Therefore,a comprehensive analysis found that spraying 100 mg/L of organic selenium fertilizer on the leaves of seedless wampee trees was the most effective way to increase the selenium content in the fruit,improve the color of the fruit skin,and improve the internal quality of the fruit.
