Abstract:
In order to explore the effects of different fertilizers on the mycorrhizal and soil physical and chemical properties of blueberry，six treatments (CK，DP，HH，KS，LZ and HF) were used to study the effects of the 7-year-old rabbit-eye blueberry ‘Britewell’ on the influence of mycorrhizal state and infection rate，root activity，malondialdehyde (MDA) content in root system，main nutrient content in soil and blueberry yield.The results showed that the mycorrhizal fungi were common in blueberry，and the mycorrhizal infection rate of DP treatment was the highest，and reached grade 3 with HH and KS treatments.The root activity of blueberry was significantly increased by five fertilization treatments (P<0.05)，and the root activity of blueberry was the highest by DP treatment.The malondialdehyde content of blueberry root was significantly decreased by five fertilization treatments.The number of fruits，fruit setting rate，single fruit weight and yield per plant of LZ treatment reached a higher level than other treatments.In conclusion，LZ，HF and DP treatments could significantly reduce soil pH，enhancing the comprehensive fertility of soil as a whole and increase blueberry yield.Therefore，in blueberry production，it was suggested that the contents of soil organic matter，organic acid and total potassium should be increased appropriately to increase the mycorrhizal infection rate and root activity of blueberry，and to reduce the MDA content of blueberry root system.
