Effects comparison of biostimulants on growth and quality of tomato
To investigate effects of different types of biostimulants on tomato growth and quality,three types of biostimulants were se-lected for experimental research,including plant derived amino acid(extracted from corn),animal derived amino acid(extracted from fish),and alginate(extracted from seaweed).Results showed that all three types of biostimulants could promote growth of to-mato roots,stems,and leaves,and all had a yield increasing effect,with yields increasing by 11.3%,36.9%,and 13.9%respect-ively compared to the control.Animal derived amino acid biostimulants had a more significant yield increasing effect.Application of biostimulants could significantly increase Vc,lycopene,sugar acid ratio,and protein content,thereby improving tomato quality.Among them,animal derived amino acid biostimulants had a more significant effect on improving quality.It could provide a theoretical basis for application of biostimulants in facility tomato cultivation.
