The genetic analysis was carried out for 8 characters on 9 energy cane parents and their 20 combination crosses with the NCII mating design. The results showed that the inheritance of stalk biomass, brix weight, available stalk numbers and weight per stalk was subject to both additive gene effect and non-additive genes effect, but mainly controlled by non-additive genes. The inheritance of plant height, stalk diameter and brix was subject to both additive gene effect. The broad sense heritability (HB2) of stalk biomass and brix was over 50%, and those of brix weight were 33.7% at the seedling stage 54.4% at its ratooning stage, respectively , which means that the selection would be done better at the early stage in the sugarcane breeding program.

The more degree shaded treatments were, the more biomass was allocated to the below-ground parts, resulting in the less ratios between above-ground and below-ground biomass.

V. spinulosa adapted the change of light by means of refuging life-history strategy.

Results show that microbial biomass carbon and microbial biomass nitrogen in fertilized soil peak in the first several days, and then decline. Incubating both sweet maize straw and white clover have the highest yield, maxima of 529.57 mgkg^(-1) and 75.50 mgkg^(-1) respectively. They also release respired CO2 the most among all treated soils. The best mineral nitrogen release is in white clover incubating, with a maximum of 29.81 mgkg^(-1) under a 26-day culture, and then keeping 1.60 times the control and reaching 2.48 times at 80-day culture. Sweet maize incubating has the least mineral nitrogen release. It is 13%~53% of the control under a 26-day culture, with a maximum of 7.51 mg kg^(-1). Soil nitrogen mineralization is insignificant under sweet maize incubating with urea in short-term.
