摘　　要：通过试验和调查,研究了安徽省杂交中籼稻发生倒伏和早衰的影响因素,结果表明,除了品种的遗传因素以外,肥、水管理不当和病虫危害是造成倒伏和早衰的主要原因。从土壤调控、旱育壮秧、肥水管理和化学调控等方面提出了杂交中籼稻防倒延衰栽培技术。The affecting factors of lodging and senescence in mid-season indica hybrid rice of Anhui Province were analyzed through experimentation and investigation. The results showed that, besides the difference of genotypes （ rice varieties）, the mismanagement in fertilization and irrigation and the damage by diseases and insect pests were the major reasons of lodging and senescence. The integrated cultivation techniques to prevent lodging and senescence of mid-season indica hybrid rice were put forward from the aspects of soil regulation, seedling raising method, water and fertilizing management and chemical control, etc.
