Effects of applying SC27 microbial soil fertility intensifier on orange
Published 2001-11-01Get full textThe effects of SC27 microbial soil fertility intensifier on yield and quality of orange were studied. The results showed that growth of orange tree promoted and yield increased in a ratio of 7.2%-23.4% by SC27. It also showed that SC27 improved the quality of orange greatly by increasing weight of s...
