Abstract:

Gibon package fertilizers (T1), Xinjingu package fertilizers (T2) and Stanley compound fertilizers (CK, namely the conventional fertilization) were used to set up three fertilization treatments. The effects of different fertilization treatments on physical and chemical properties of soil, yield, quality and economic benefits of kiwifruit were studied by field experiment to provide certain references for the high quality and efficient production of kiwifruit in Zhouzhi County. The results showed that: (1) compared with CK, T1 and T2 treatments had no significant effect on soil bulk density and pH, but they were helpful to improve soil organic matter content and reduce soil electrical conductivity; (2) compared with CK, T1 and T2 treatments could increase kiwifruit weight and total yield, especially T2 treatment, which increased the weight of single fruit by 7.83% and the yield by 19.50%, respectively; (3) compared with CK, T1 and T2 treatments could improve the content of soluble solids and vitamin C in kiwifruit to some extent, especially T2 treatment had the best effect, the content of soluble solids and vitamin C in kiwifruit increased by 28.10% and 13.32%, respectively; (4) compared with CK, T1 and T2 increased the profit by 19.25% and 26.41%, respectively, and T2 increased the profit more significantly. On the whole, the application of the two kinds of package fertilizers, especially Xinjingu package fertilizers, can better realize the purpose of cost saving, benefit and income increasing.
