The Investigation of Sugarcane Productions and Growing Situations in Seedlings Stage on the Southwest of Guangxi Plantation in 2020/21 Grinding Season

In order to provide scientific basis for sugarcane production and management,the sugarcane crop growing situations of seedlings stage was carried out to survey on the southwest of Guangxi plantation in 2020/21 grinding season.General investigation,statistical data collection and field investigation were combined for the survey which general investigation was collected form sugar industry departments of government,companies and sugarcane farms,and field investigations were surveyed by 62 plant and 91 ratoon crops of total 153 samples.The results showed that the average of temperature was increased 0.1~2.1℃on January.to May in 2020.And the total precipitation was more than the same period last year by 10%~60%.Comparing with 2019/20 grinding season,plantation area of Baise,Chongzuo and Fangchenggang were increase by 3.69%,0.97%and 6.08%in 2020/21 grinding season,respectively.Main cultivators of Guitang42 and Liucheng05-136 were increased of 7.4%~78.7%and 48.6%~116.0%,respectively,but the plantation area of ROC22 was largest decreased by 81.1%in Fushui county.Basic of the investigation,the sugarcane growing situation of southwest in Guangxi plantation is better than last year.Chongzuo had got the highest of plant height and the lowest of diseases and insects damage.It was suggested that adjusting the structure of sugarcane varieties to local sugarcane cultivation conditions,combining agricultural agronomic tech to machinery,reducing the sugarcane production costs gradually and increase economic benefits,creating planting&raising mode of circulation,and promoting the development of sugarcane industry.
