| Abstract: | 162 soil samples of Longchuan sugarcane field, Yunnan province were analyzed to test index including nitrogen, phosphorus, potassium, soil organic matter, pH value, and 16 soil samples used to determine trace elements of Fe, Cu, Zn, Mn. The results showed as following, available nitrogen was 49.85-307.41mg·kg^-1, available phosphorus was 0.9-48.35mg·kg^-1,available potassium was 26.09-625.78mg·kg^-1, soil organic matter was 0.84-10.48%, pH value was 4.32-6.15. Available Fe was 23.64-118.36 mg·kg^-1, available Cu was 0.03-1.17 mg·kg^-1, available Zn was 0.18-1.85 mg·kg^-1, available Mn was 0.11-25.59 mg·kg^-1. Application of formula fertilization into sugarcane production for 2 years, cane yield had improved 12.75-15.75 t.ha^-1, sucrose content had raised 0.23%-0.48%, seeping sugar ratio had increased 0.14%-0.47%. |
