This study was carried out to investigate the suitable technique for increasing the stalk sugar content of two sweet sorghum cultivars (salt-tolerant cultivar Jitianza 2 and salt-sensitive cultivar Lvneng 1) in saline soils of Yellow River Delta. Stalk sugar content of sweet sorghum in saline soil was significantly increased using the following integrated cultivation technique: (1) increasing organic fertilizer level; (2) applying optimum phosphorus and potassium fertilizer; (3) surface fertilizer application; (4) cultivating salt-tolerant sweet sorghum cultivars; (5) planting with plastic mulching; (6) planting in the early of the optimum seedling time (sowing as early as possible); (7) removing tillers during seedling stage; (8) cutting spike by half-strength before flowering. Jitianza 2 had higher stalk Brix than Lvneng 1 under the same cultivation condition. Therefore, planting salt-tolerant sweet sorghum cultivars in saline soil combined with these integrated cultivation techniques can get higher stalk sugar content in Yellow River Delta of China, which was beneficial for energy alcohol production from sweet sorghum.

In order to screen out the optimum varieties of sweet sorghum to be planted in Yellow River Delta, the agronomy characters of different varieties (strains) of sweet sorghum including jitianza 1 (JZ1), jitianza 2 (JZ2), jitianza 3 (JZ3), jitianza 4 (JZ4), liaosiza 1 (LSZ1), liaotian 1 (LT1), liaotian 3 (LT3), liaotian 6 (LT6) planted in the saline soil of Yellow River Delta were analyzed; Further more, the effect of different sowing time on the agronomy characters of sweet sorghum was explored with JZ2. The study provided bases for the cultivation of sweet sorghum in saline-alkali soil of Yellow River Delta in order to transform the biomass into bio-energy such as fuel alcohol.

Field experiment was conducted in the saline soil of Yellow River Delta between May to Oct. Sweet sorghum was planted with different cultivation measures to test the effect of plastic mulch, plant density, organic manure application and additional fertilizer application on the yield, stalk juice Brix and extraction rate. The soil bacteria and actinomycetes quantities were also determined after harvesting to test the amelioration effects of different measures on soil.
