| Abstract: |
| The reaserch was to explore the effects of Bacillus Subtilis and Phosphobacteria, which supplied to the rooting zone of Kiwi fruit, on soil physical, chemical and microbial population in the rhizosphere soil and the fruit quality by orthogonal experiment of two factors and two levels in the field. The physical, chemical and microbial population of soil, leaves and fruits were measured respectively. Results showed that the trees dealt with both of Bacillus Subtilis and Phosphobacteria to the rooting zone had the best signification. The soil available P, ammonium N contents and phosphatase activity was 1.93, 1.34 and 2.15 times the amount of the unprocessed. The firmness, soluble sugar and Vitamin C content was 1.21, 1.06, 1.18 times the amount of the unprocessed. The unprocessed titratable acid was 88% of the trees dealt with both of Bacillus Subtilis and Phosphobacteria.The data being analyzed, fruit quality had a signification positive correlation with organic matter, available P contents and phosphatase activity. It is considerable to use both of Bacillus Subtilis and Phosphobacteria to improve the soil characteristic and the fruit quality. |
