| Abstract: |
| The objective of this study was to verify the effectiveness of a new type water-soluble micro-elements fertilizer, ‘Wodetian’ by foliar spray on kiwifruit trees, and to provide a scientific basis for improving the kiwifruit yield and quality in Shaanxi. A field experiment was conducted in an orchard of Qinmei kiwifruit to investigate the effects of spraying three types of micro-element fertilizers (‘Wodetian’ micro-fertilizer 1 as W1, ‘Wodetian’ micro-fertilizer 2 as W2, and a common water-soluble micro-element fertilizer as G1) on leaf growth and fruit yield and quality. A randomized complete block design was adopted for four treatments including spraying the three micro-fertilizers and local groundwater as the control (CK1). The results showed that spraying of W1 and W2 significantly increased the thicknesses of 100 kiwifruit leaves by 20% and 27%, increased the weights of 100 leaves by 22.6% and 33.3%, respectively. The W2 significantly increased the horizontal and vertical dimensions of kiwifruit leaves by 11.0% and 12.9% compared to the control. Spraying W1 and W2 also significantly increased the contents of Cu, Zn, Fe, Mn, and Ca in kiwifruit leaves, increased the Fe content by 60~78 mg·kg-1 compared with that of the G1. Moreover, spraying W1 and W2 significantly increased the weights of a single kiwifruit by 11.3% and 8.8% compared to the control, and significantly increased the soluble solids-acids ratios in kiwifruits. The W2 specially increased the content of vitamin C by 8.6% in kiwifruit. Furthermore, spraying W1 and W2 enriched the contents of micro-nutrients and Ca to various degrees, which also promoted the appearance and nutrient quality of kiwifruit. In addition, the W1 and W2 increased the kiwifruit yields by 8.11% and 5.17%, and increased the economic benefits by 8.83% and 5.43%, respectively. Particularly, the W1 and W2 were all better than the common water-soluble micro-element fertilizer in promoting the yield and quality of kiwifruit. Therefore, it indicated that the ‘Wodetian’ micro-fertilizer products (W1 and W2) are both remarkable in improving quality and increasing benefit. Therefore, they have significant effect to extend and be used in the main producing area of kiwifruit in Shaanxi province. |
