Effects of the Contents of Mineral Elements on Gummosis in Prunus salicina Lindl.

To investigate the relationship between mineral elements and plum gummosis disease, Prunus salicina Lindl. trees with four grades of were used as experimental materials. The contents N, P, K, Ca, Mg, B, Fe, Mn, Zn Cu in branches leaves measured, correlation was systemically analyzed through multiple comparisons, binary logistic regression analysis, ordinal analysis. In addition, effects prevention control necessary on disease P. verified after a fertilization experiment. results indicate that nitrogen manganese positively correlate occurrence gummosis. contrast, calcium boron significantly negatively A experiment facilitated discovery nitrogen, well increased application fertilizers, contributed to
