Ecological Study on High Yielding Cultivation of Sugarcane ROC 1 in Winter──III.High yielding agronomic practices and their effects
The functions of high-yielding agronomic practices such as film -mulching, planting patterns and fertilizer application were studied. The effects of different agronomic practices on growth, yield, sugar content and environmental factors were analyzed in detail.The results showed that the film-mulched failed to have a significant effect on sugarcane ROC1 in Danzhou area while the planting pattem of shallow-furrow with single row was advantageous to the population growth of sugarcane, and judicious application of special fertilizer to sugarcane reduced application rate and hence reduced production cost consid erably.
