This test is a new machine sugar cane varieties, 22 for test materials, in the growth of sugarcane, equivalent to rainfall during the ten-day 20mm / (A1), 40mm/ten-days (A2), 60mm/ten-days (A3) three different water treatment facility, the pure nitrogen 12kg 666.7 / m2 (B1), 24kg 666.7 / m2 (B2), 36kg 666.7 / m2 (B3) three different nitrogen treatment, composed of nine different treatment combinations. Study the different water treatment, different nitrogen fertilization of different coupling and economic characters, sugarcane agronomic characters. Test results show that:
In this experiment, within the scope of the sugarcane weight of single stem stem diameter, main yield with water and nitrogen increases with the trend of the nitrogen increases. Low nitrogen treatment for sugar accumulation, can improve the quality of sugarcane juice, The combination of production, the processing 667m2 sugarcane A1B3 (6276kg 666.7 / m2) and sugar 945.44 (kg), but the lowest sugar, A3B2 processing of single stem, stem diameter both yield better, and sucrose points (15.95%) and purity of gravity (86.73% sugarcane juice in combination with the second) may and June, if can reduce water, increase effective number is expected to become the best treatment, combination.
