Abstract:
In order to study the effects of fertilization methods on the growth, yield and quality of pear trees, four fertilization methods were set, namely trench application(T1), hole application(T2), spread application(T3) and radial application(T4), with no fertilization as the control, and the growth traits, photosynthetic parameters, yield and quality indexes of pear trees were measured respectively. The experiment showed that fertilization significantly promoted the growth and yield of pear trees. The branches length, louver weight, net photosynthetic rate, stomatal conductance and transpiration rate of radiative fertilization treatment were significantly higher than those of other fertilization treatments, and the yield was 57.20% higher than that of control. The fruit weight, diameter,hardness and Vitamin C content of single fruit were significantly improved. Therefore, radial fertilization can improve the quality of pear trees obviously, and it is a suitable fertilization method for pear cultivation.
