| Sugarcane Yuetang 60 and Roc 22 were virus-freed by hot water treatment and axillary buds detoxifying treatment, and the survival rates of transplanting, qualities and yields of them were analyzed. The result showed that the germination rate, tiller rate and the number of effective stems of Roc 22 healthy seedlings made no significant difference from the conventional ones in the earlier stage, but the plant height of healthy seedings were much higher than the general ones;In the harvest stage, the stem length, single-stem weight, number of effective stem and yield of healthy seedlings were significantly higher than concentional ones; Among then, the cane yield and the sucrose content increased by 42% and
0.41%, respectively. In addition, the germination rate, tiller rate, plant height and the number of effective stems of healthy Yuetang 60 seedlings were significantly higher than the general ones in the earlier stage; In the harvest stage, the single-stem weight, number of effective stem and the yield of healthy seedlings were also much higher than the general ones; the cane yield and the sucrose content increased by 18.4% and 0.34%, respectively. The cane yield of Yuetang 60 conventional seedings increased by 44.3% and the sucrose content increased by 0.94% compared to Roc 22; The cane yield of healthy Yuetang 60 seedlings increased by 20.2% and the sucrose content increased by 0.87%. In addition, the reseach indicated that the survival rate of temporary planting could reach 98% when cultivated with fine river sand (1-2 centimeters) on the surface and filter mud on the base as a base fertilizer in the subsurface soil in the outside. |
