Abstract:
In order to analyze the effects of different combinations of foliar fertilizers on the growth and yield of wolfberry trees，‘Ningqi No.5’ red wolfberry was used as the test material,and a two-factor three-level two-way random block design method was used to spray urea and phosphoric acid.Field trials of mixed aqueous solutions of different concentrations of urea and potassium dihydrogen phosphate.This study can provide a reference for the leaf fertilization and efficient production of wolfberry.The results showed that,1)The mixed solution of urea and potassium dihydrogen phosphate had better effects on the growth index and yield increase of ‘Ningqi No.5’ red wolfberry than the effect of urea or potassium dihydrogen phosphate alone.2)The concentration of urea was 3 g?L-1基基，and the concentration of potassium dihydrogen phosphate was 1 g?L-1基.The best effect was the mixed application,which had the most significant effects on the new diameter,the new length,the crown width and the yield of the wolfberry tree.3)Through the interaction analysis,the amount of urea was 2.527 g?L-1基,and the amount of potassium dihydrogen phosphate was 1.591 g?L-1基,when the ratio of the two was 1∶0.630,the crude growth of the new diameter reached the theoretical maximum,and the highest increase was 1.744 mm;the dosage of urea was 2.591 g?L-1基 and the dosage of potassium dihydrogen phosphate was 1.612 g?L-1基,when the ratio of the two was 1∶0.622,the new slightly longer growth amount reached the theoretical maximum,and the highest increase was 48.479 cm;urea the dosage was 2.641 g?L-1基基,and the amount of potassium dihydrogen phosphate was 1.665 g?L-1基,when the ratio of the two was 1∶0.630,the crown width increment reached the theoretical maximum,and the highest increment was 23.955 cm;the urea dosage was 2.825 g?L-1基,the amount of potassium dihydrogen phosphate was 1.451 g?L-1基,when the ratio of the two was 1∶0.514,the yield of wolfberry reached the theoretical maximum,and the highest yield was 12.830 kg.The combined application of urea and potassium dihydrogen phosphate can significantly promote the growth and yield of wolfberry trees.Within a certain concentration of fertilizer use,the biological increase of the four indexes of wolfberry new diameter was larger,the new length was longer,the crown width,and the yield increase.The gradual increase in concentration showed a trend of increasing first and then decreasing.
