Abstract:
The fruits of Jiuqian plum at different growth stages were used as test materials.The indexes of fruit nutrients and mineral element accumulation were determined and analyzed by anthrone method and mass spectrometry.The accumulation law of nutrients and mineral elements in Jiuqian plum fruit was studied,in order to provide reference basis for scientific fertilization of Jiuqian plum.The results showed that during the fruit development period of Jiuqian plum，the transverse and longitudinal diameter and shape index of the fruit continued to increase，the fruit changed from long strip to oblate，and the dry weight content of the fruit was low in the first and middle stages，so water management should be carried out.During the fruit development period of Jiuqian plum，the accumulation rate of titratable acid showed a law of fast-slow-fast，the accumulation rate of total phenol showed a downward trend，and the accumulation rate of sugar showed a trend of slow first and then fast.With the growth and development of Jiuqian plum，the accumulation of mineral elements in the fruit showed an upward trend.The accumulation of mineral elements in the whole fruit growth period was K>N>P>Ca>B>Fe>Cu>Mg.The fruit had the greatest demand for K and N.The early stage of fruit development of Jiuqian plum (the first 30 days after flowering) was the key period of fertilization.The application of nitrogen and potassium fertilizer and water management should be strengthened，phosphorus and calcium fertilizer should be applied at the same time，and Mg，B and other trace element fertilizers should be supplemented appropriately according to the soil fertility.In the middle and late stage of fruit development of Jiuqian plum，the application of N and K fertilizer should be reduced，but trace element fertilizer should be supplemented.
