摘要
Abstract
The sugarcane fertilization experiment was conducted to test effect of applying organic, phosphate and potassium fertilizer as base fertilizer, the nitrogen fertilizer of 6 treatments as after manuring under different stages and application amount in comparison with the conventional fertilization in the Longling area. The results showed that: the treatment B (1/4 nitrogen fertilizer applied at seed bed and later growing stage, 2/4 nitrogen fertilizer applied at elongation stage) was superior to the others, the cane yield was up 109.02 t/ha, increased by 18.08 t/ha (19.88%);sugar yield was 13.55 t/ha, increased by 2.64 t/ha (24.2%), in comparison with the treatment A, conventional fertilization (all nitrogen fertilizer applied at elongation stage). Therefore, the treatment B was very effective to increase cane yield and sugar yield.关键词
