摘要
为筛选出适用于京郊草莓生产的海藻酸肥,以‘红颜’草莓为供试材料,选择市场关注度较高的4种海藻酸肥产品,通过田间试验,研究不同海藻酸肥对草莓生长性状、产量和品质的影响。结果表明,不同海藻酸肥处理均可促进草莓植株的生长,以海藻精海藻酸肥处理(T_(2))的株高和叶柄长效果最好,与清水对照处理(CK)相比,128号棚株高显著增长32.0%,234号棚叶柄长显著增长25.71%。海藻酸肥可以通过提高果个数提高草莓产量,与CK处理相比,128号棚T_(2)处理产量显著增加18.47%,234号棚T_(3)处理显著增加23.36%,各海藻酸肥处理间差异不显著。海藻酸肥可以提高草莓果实品质,提高可溶性固形物含量、糖酸比和维生素C含量,降低可滴定酸和硝酸盐含量。研究认为,海藻酸肥可以促进草莓生长、提高产量、改善品质,并以T_(2)处理施肥效果最佳。
The primary objective of this study was to screen the most effective alginate acid fertilizers for enhancing strawberry production in the suburban areas of Beijing.To conduct this research,the‘Hongyan’variety of strawberries and commonly used alginic acid fertilizers were specifically chosen as experimental materials.Field trials were meticulously carried out to evaluate the impact of alginic acid fertilizers on the growth,yield and quality of strawberries.Compared to the CK group(water control treatment),the application of diverse alginate acid fertilizer treatments could promote the growth of strawberry plants.The T_(2) treatment(Haizaojing alginic acid fertilizer treatment)consistently exhibited superior effects on both plant height and petiole length within the two sheds.For instance,in shed 128,the plant height experienced a significant increase of 32.0%,and in shed 234,the petiole length had a substantial increase of 25.71%under the influence of the same treatment.Furthermore,the application of alginate acid fertilizers corresponded to a marked rise in the number of fruits per plant,consequently amplifying the overall yield.Notably,in shed 128,the implementation of the T_(2) treatment led to a noteworthy 18.47%increase in yield compared to the CK treatment.And in shed 234,the yield significantly increased by 23.36% with the application of the T_(3) treatment(Dalantong alginic acid fertilizer treatment).However,no significant differences were observed among the various alginate acid fertilizer treatments.The application of alginate acid fertilizers could improve fruit quality,such as increasing soluble solid content,sugar-acid ratio and vitamin C content,and reducing titrable acid and nitrate content.A comprehensive analysis of the findings emphasizes that alginic acid fertilizers play a pivotal role in promoting strawberry growth,elevating yield,and improving fruit quality.The T_(2) treatment has the best effect for multiple parameters.
