Production problems and cultivation measures of sustainable benefit of cassava

The problems are monoculture leading to poor efficiency,extensive management and lack of fertilizer,yields lower for production of cassava.Efficiency increase per unit area yield benefit,can improve land utilization rate,by cassava intercropping peanut;application of organic fertilizers and biological nitrogen fixation,a significant increase in pressure vine can fertilize the soil organic matter content,soil nutrients more comprehensive,providing nutrients for the growth of cassava,fertilizer is longer,so that cassava cultivation to reach sustainable efficiency;the yield increase for selection of new cassava variety southern china 8,southern china 5,GR911,can effectively improve yield per unit area of cassava.
