[Method] One species is planted in each region, and there were two controls dripping technology or no-dripping technology in each region. [Results] The average yield of dripping-pro- cessed land was 115.91 t/hm2, which was 19.73 t/hm2 higher than the control. The maximum output was GT31, followed by GT34. The output of all Guitang new species was higher than the control ROC22. The average sucrose of dripped sug- arcane was 14.68%, which was 0.19% less than the control of 14.83%. The drip- ping technology was economically beneficial, rising by 15.2% compared with the control. The highest dripping efficiency was GT31, while the lowest one was ROC22. The increasing ratios of drip irrigation efficiency of the tested new Guitang species were higher than ROC22. [Conclusions] Under the drip irrigation condition, the sugarcane yield was extremely higher than the control of non-dripping irrigation, and the economic efficiency was significant. However, the sugar in the sugarcane declined slightly. The sensitivity of several new Guitang species to water was higher than the control ROC22.展开更多

Nine sugarcane varieties were chosen to study their agronomy and yield potentials in comparison with the control vari- ety Roc22. The agronomic characters studied were the sprouting rate, tillering rate, cane production, sugar content, chilling tolerance and sugar production per unit area. Results showed, compared with the control, YT55, Funong15, GT02-901 and YT00- 236 had higher sprouting rate. YT55 and YT00-236 showed higher tillering rate than Roc22. Four varieties, YT55, GT97-69, YT00-236 and Funong15, gave higher cane production than the control. GT02-901 and Y799-21 had the highest sugar content and YT55, Funong15, YT00-236 and GT97-69 produced more sugar per hectare. YZ99-91, YZ03-422, YT55 and YT00-236 showed improved chilling tolerance. It was concluded that YT00-236 and Funong15 are the top two sugarcane varieties with comprehensive advantages and could be widely disseminated through the main sugarcane producing regions in China.展开更多
