Effect of Alginic Acid Fertilizer on Growth,Yield and Quality of Strawberry
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 T2 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 T2 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 T3 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 T2 treatment has the best effect for multiple parameters.
