Effect of Different Base Fertilizer on the Soil Nutrient and Quality of Prunus salicina 'Oishiwase'

Taking Prunus salicina‘Oishiwase'as test material,the effects of armyard manure,edible fungi residue,and slow release fertilizer on the soil nutrient and fruit quality were studied.The results showed that the farm manure significantly increased the soil organic matter,total nitrogen,total phosphorus,available potassium,it better than other treatments,were increased by 60.61%,79.08%,26.00%,41.44%.Edible fungi residue had the most significant effect to improve the soil available phosphorus,it was increased by 43.51% than CK.Slow release fertilizer had more obvious effect on total potassium than the other treatments,it was increased by 10.05%.Farmyard manure increased fruit firmness,the total soluble solids content,fruit soluble sugar content,vitamin C content by 25.98%,16.15%,49.39%,27.42%,soluble acid content decreased by 19.39%,it had the most significant effect.Farmyard manure could improve the fruit calcium,magnesium,zinc,iron,it was better effect than other treatments,and the effect of slow release fertilizer on improving the fruit mineral element was not significant.3treatments had a significant effect on increased fruit weight,edible fungi residue was the best,and the weight was increased 27.45%.Slow release fertilizer can obviously improve the plum yield,the plum yield per plant was 74.86 kg,it was increased 54.83% higher than the control.
