Abstract:

To enhance the fruit quality and commodity value of ‘Xinghuayin’ pear, using orchards before and after transformation as research objects, we deeply ploughed the orchards using combined application of organic and inorganic fertilizer, and studied the changes of soil nutrient, soil microbe, soil enzyme activities, fruit basic quality, fruit anino acids and fruit aroma component. The results showed that after the combined application of organic and inorganic fertilizer, the content of available P and available K, the microbe quantity, the activity of sucrase, the activity of peroxidase, the content of total animo acid, the content of esters in aroma substance were increased by 63.79%, 252.30%, 203.43%, 202.18%, 100.00%, 78.22% and 524.92%, respectively. Each index had significant difference between treatments with and without bio-organic fertilizer (P<0.05). The research indicates that the combined application of organic and inorganic fertilizer could significantly improve soil nutrient contents and fruit quality.

Key words: combined application of organic and inorganic fertilizer, ‘Xinghuayin’ pear, fruit quality, amino acid, aroma component
