| 【Objective】The research was to investigate the effect of sugarcane wide row planting and local
conventional planting distance(1.0 m) on the yield and quality of ratoon sugarcane and the adaptability of different varieties
to different row spacing, explore the sugarcane varieties adapted to different harvesting machinery and sugarcane ratoon wide
row distance management technology, and provide a basis for the wide spread of sugarcane mechanical harvesting. 【Method】
The test was conducted based on a test of different sugarcane planting intervals in a year. In the second year, live roots were
observed in this experiment A test for newly planted sugarcane at different row spacing was conducted, leaving ratoon for
observation. Three good varieties including GT 29, FN 39, and YT 60 were used as tested sugarcane varieties, and three
different row distances (1.0,1.2,1.4 m) were designed to study their agronomic traits. 【Result】 Under the row spacing of 1.4
m, GT29 had a sugar content of 734 kg per 667 m2, which was 26.99% higher than that of the control, while the wide-rowspacing planted YT60 had a sugar content similar to that of the control. The comprehensive performance of agronomic and
yield traits of GT29 and YT60 under wide row spacing planting was better than that of the control, which indicated that GT29
and YT 60 had good adaptability to wide row spacing planting. 【Conclusion】 FN39, which has no advantage in wide row spacing planting, is not suitable for medium and large scale mechanization planting management. GT29 has good adaptability
to wide row spacing planting, and a row spacing of can be regarded as 1.4m as the optimal raw spacing for full mechanization
planting. |
