Effects of Amino Acid Water-Soluble Fertilizer on Growth and Nutrient Absorption of Loquat Seedlings
[Objective]To explore the effects of amino acid water-soluble fertilizer on the growth and nu-trient absorption of loquat.[Method]Using one-year seedlings of'Dawuxing'(Eriobotrya japonica L.)as experimental materials,spray amino acid water-soluble fertilizers diluted 0(control,distilled wa-ter),50,100,150,and 200 times,and measure relevant physiological indicators.[Result]Amino acid water-soluble fertilizer increased the biomass of loquat seedlings,And the root and aboveground bio-mass of loquat seedlings were the highest at 100 times,increasing by 21.45％and 44.41％respectively compared to the control.Amino acid water-soluble fertilizer increased the total nitrogen,total phospho-rus,and total potassium content of loquat seedlings,and the total nitrogen and total phosphorus content in the aboveground part of loquat seedlings were the highest at 100 times,increasing by 70.01％and 32.49％respectively compared to the control;When the amino acid water-soluble fertilizer was 150 times,the total potassium content in the aboveground part of loquat seedlings was the highest,which in-creased by 36.44％compared to the control.Correlation analysis and grey correlation analysis indicated that the total nitrogen,total phosphorus,and total potassium contents of loquat seedlings were closely re-lated to biomass,indicating that amino acid water-soluble fertilizer promoted nutrient absorption and growth of loquat seedlings.[Conclusion]Amino acid water-soluble fertilizer can effectively promote the growth and nutrient absorption of loquat seedlings,and the best dilution ratio is 100 times.
