南方三熟稻区双季稻超高产栽培研究进展

The Research Progress of the Super High-yielding Cultivation for Double Rice under Tri-cropping System in Southern China

本文对南方三熟制双季稻的发展作出了基本评价,认为过去三熟制的发展对提高我国粮食总产起到了重要作用,将来提高复种指数和土地生产效率仍是我国农业发展的主要方向之一.本文通过分析三熟制双季稻实现高产的主要障碍,以近年来洞庭湖三熟制双季稻高产的成功实践为基础,探讨了三熟制双季稻实现超高产的光温资源利用理论与策略、高产栽培配套技术.提出了三熟制双季稻超高产需要进一步研究的课题.

The basic comments have been made on the development of double-rice under tri-cropping system in southern China in this article. Developing the double-rice under tri-cropping system played important roles in the food output increasing in the past 50 years while increasing the index of multiple cropping will become one of the major techniques for future agricultural development. According to the successful high-yielding practice of the double-rice under tri-cropping system in Tongtinhu Area, this article has discussed the obstacles to reach the super yield, dealt with the theory and techniques to utilize the resources of light 8V- temperature and laid out the package of techniques for the super yield. This article also bring up further topics need to be studied for the super-high-yielding of double-rice under tri-cropping system.
