摘要
甘薯是重要的粮食、饲料和工业原料作物。总结并评述了不同环境因子、无机营养、内源激素以及盐胁迫对甘薯生长发育、块根膨大的影响及其与环境的关系。指出应综合考虑各生态因素,采取相应的农业技术措施,提高甘薯干物质总产及其在块根中的分配比例,协调好源库流间的关系,才能实现甘薯的高产优质和可持续发展。
Sweet potato is a good multi -use crop for food, feed and raw material. The article conducted to elucidate the rules of accumulation and distribution of materials assimilated and the effects of different environmental factors, fertilizer, endogenous hormone and salt stress on the growth and development, formation and enlargement of tuberous root. It showed that the relation between sweet potato and environment and agricultural measures was intricate. Therefore, high yield and high quality, sustainable development could be achieved by comprehensively considering the ecological factors, taking the appropriate measures, enhancing dry matter yield and the allocation proportion of dry matter in tuberous root, coordinating the relation between source, sink and flux.
