Abstract
【Objective】The effects of drip irrigation technology on agronomic,physiological and biochemical traits,quality traits and yield of ROC22 in elongation were studied to provide references for sugarcane irrigation research. 【Method】The experiment carried out in the field included drip irrigation and conventional irrigation treatments. Drip irrigation was conducted once in prophase,interim and late stage of elongation and drip irrigation capacity was 60 m3/ha. Conventional irrigation was set as the control. The tested indexes were agronomic traits including height,stem diameter and leaf area,and physiological and biochemical traits including chlorophyll,SOD,MDA,soluble protein and soluble sugar and quality traits including reducing sugar in juice,sugar,sugarcane fiber and yield. 【Result】Plant height, stem diameter and +1 leaf area of sugarcane in elongation under drip treatments were all higher than those of the control and the plant height was significantly higher than that of the control(P0.05,hereinafter),and the differences of the remaining indexes were not significant. Chlorophyll,SOD,soluble protein and soluble sugar content of sugarcane under drip irrigation treatments were higher than those of the control. SOD activity was significantly higher than that of the control and the remaining differences of index were not significant. MDA was lower than that of the control and the difference was not significant. Compared with the control, reducing sugar in juice,sucrose and sugarcane fiber under drip irrigation treatments increased by 8.89%,7.50% and 6.13%,respectively. However, the difference was not significant. Compared with the control,effective stems and yield under drip irrigation treatments increased by 25.43%and 27.26%, respectively and the difference was significant. 【Conclusion】Compared with conventional irrigation,effects of drip irrigation technique on field sugarcane in elongation are superior.
