Guangxi sugar industry is an important economic pillar industries. Importance of the sugar cane industry research, development and promotion, to accelerate economic development in Guangxi is very important. Sugarcane is a perennial and annual herbaceous plants, the quality of ratoon sugarcane growth, a direct impact on the development of sugar industry. Strengthen the management of ratoon cane, sugar cane from the root to reduce production costs and improve efficiency of China's sugar cane industry to develop healthily, to improve the competitiveness of our guarantee. Ratoon cane in the field management measures, water management is the most common is also one of the most effective measure. Proper water management, will have a direct impact on ratoon cane yield and quality, thus affecting the level of benefits to sugar cane. In accordance with botany principle, the role of water in the sugar cane when coupled with the obvious effect of water is to play a key fertilizer, manure is open land and water systems of the key production performance. The test greenhouse smart cane for the research and production base, through a variety of water and fertilizer processing, artificial control of the growth process of sugar water and nutrient requirements. Through the combination of all to deal with the results of the investigation, comparison and analysis, to explore different combinations of water and fertilizer on sugarcane agronomic and economic characters, the interaction of water and fertilizer application in sugar cane and reasonable application of the program to develop and provide a theoretical basis.
