木薯生产存在的问题及可持续增效栽培措施

我国木薯生产普遍存在单一栽培导致效益较差、管理粗放和缺少施肥、产量较低等问题。通过木薯套种花生,可提高土地利用率,增加单位面积的产出效益;施用有机肥和生物固氮肥、压藤培肥可以大量增加土壤有机质含量,土壤营养成分较全面,可为木薯生长提供养分,肥效较长,使木薯栽培达到可持续增效;选种木薯新品种华南8号、华南5号、GR911,可有效地提高木薯单产,增加木薯产量。

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.
