【摘要】【Objective】This experiment studied the changes of soil physical and chemical properties and enzyme activity of funong 41 sugar cane in different growth stages under different fertilization conditions. Through the comparison of sugarcane yield and quality and root system, the optimal fertilization method was selected to provide theoretical basis for sugarcane to maintain and increase yield, improve soil fertility and optimize fertilization scheme.【Method】The experiments of organic fertilizer and compound fertilizer(ONPK), slow release bag control(DNPK), single compound fertilizer(NPK), organic fertilizer(O) and no fertilizer(CK) five treatment were designed, and the sugarcane production quality and the length of root surface area, and the enzyme activity of soil physical and chemical properties were analyzed.【Result】Compared with other treatments, the yield of sugarcane stems increased by 38.12 %-76.59 %, and the sugar yield increased by 33.97 %-80.42 %,and promoting root growth;In sugarcane tillering stage, the soil nutrient content was the best, including ONPK treatment than other fertilizer treatment had significant difference(P < 0.05) in soil organic matter, alkali-hydro nitrogen, available P, available K content than other treatment increased by 1.94 %,22.52 %,6.54 %,15.93 %, 3.26 %,24.13 %, 11.79 %,32.93 %; The differences of soil urease, sucrase and acid phosphatase were not obvious in the whole growth period, and the enzyme activity was the largest in the mature stage. However, the soil urease, sucrase and acid phosphatase treated by ONPK were significantly higher than other treatments, increasing by 7.90 %-28.13 %, 12.23 %-20.06 % and 10 %-46.67 %;Compared with other treatments, the yield and sugar yield of sugarcane treated by NPKD had no significant advantage, which was consistent with the variation range of soil nutrient content between NPK treatment and O treatment, but the soil enzyme activity was only lower than that of ONPK treatment, and the soil urease, sucrase and acid phosphatase increased by 2.70 %-18.75 %, 5.14 %-6.98 % and 33.33 %-21.21 %,respectively.【Conclusion】The mixed application of organic fertilizer and compound fertilizer can promote the development of sugarcane root system, improve the yield and quality of sugarcane, improve the physical and chemical properties of soil and enzyme activity, and improve the soil enzyme activity to a certain extent by slow-release bag controlled fertilization.
