Abstract:

Perennial rice varieties and their supporting techniques have been applied in production for many years. However, the safe overwintering, green and light simplified cultivation techniques of perennial rice varieties in high-altitude rice areas still need to be explored. Since participating in the perennial rice project led by Hu Fengyi’s team at Yunnan University in 2016, the author has explored a set of green, efficient and safe overwintering production techniques for “perennial rice+fish” in high-altitude (1 670 meters) rice areas, mainly including the selection of perennial rice varieties, seedling cultivation and transplantation, fertilizer and water management, disease and pest control, and fish management in rice fields, as well as the management techniques of rice piles, water, fertilizer and fish in winter, and the management techniques of rice and fish in the following year.

Key words: perennial rice, fish, safe overwintering, green and efficient production technology

摘要：

多年生稻品种及其配套技术已在生产上应用多年。但是，多年生稻品种在高海拔稻区安全越冬、绿色轻简化栽培等田间管理技术仍有待探索。自2016年参加云南大学胡凤益团队主持的多年生稻项目以来，作者经过多年实践，探索出一套高海拔（1 670 m）稻区“多年生稻+鱼”绿色高效安全越冬生产技术，主要包括多年生稻品种选择、育秧移栽、肥水管理、病虫害防治和稻田鱼管理，以及越冬季稻桩、水肥、鱼的管理和次年后的稻鱼管理技术。
