Effect of 3 Long-acting fertilizer on the quality and yield of Prunus salicina Lindl.

In order to explore the effect of farmyard manure,edible fungi residue,and slow release fertilizer,as basal fertilizers on the high yield and quality of Prunus salicina Lindl.Liwang,Black amber and Angeleno were used as test materials for fertilizer experiments.The result showed that farmyard manure had a better effect on improving fruit hardness,soluble fruit solids,soluble sugar,and titratable acid.The fruit hardness of Liwang,Black amber and Angeleno was increased by 28.86%,44.41%,and 34.88%,with the content of soluble fruit solids increased by 26.69%,22.24%,and 15.04%,the content of soluble sugar increased by 42.79%,20.36%,and 26.39%,but the content of titratable acid decreased by 31.45%,15.28%,and 19.84%respectively.Edible fungi residue significantly improved the content of fruit vitamin C.with Vc content of Liwang,Black amber,and Angeleno increased by 28.09%,17.95%,and 26.80%,respectively compared with the control,and simultaneously increased the fruit weight remarkably,with 93.37 g,112.20 g,and 89.83 g fruit weight of Liwang,Black amber,and Angeleno,which were increased by15.74%,31.84%,16.10% respectively,higher than the control and better than other treatments.Slow release fertilizer significantly increased the yield of Liwang,Black amber,and Angeleno,reaching 58.38 kg,58.68 kg,and 47.12 kg per plant,which were increased by39.20%,29.71%,and 34.67%,respectively compared with the control group.Therefore,it has the best effect,with very significant differences among the three treatments.
