Study on Climatic Resources for High Quality Rice Production in Chongqing and Their Utilization

This paper studies the relationship between the growth and development of high-quality rice and meteorological conditions, analyzes the main climatic factors which influence the quality of rice, and discusses the climatic resources for the cultivation of high-quality rice and their distribution in Chongqing. Based on such analyses, it points out the advantages and disadvantages of climate in Chongqing. An ecoclimatic regionalization for high quality production is developed. The paper proposes that the advantages of the climatic resources should be fully used, and high-yielding, good-quality and disease-resistant rice cultivars suitable to the local eco-climatic conditions and their corresponding agronomic practices should be adopted. The construction of a complete system integrating cultivation, processing and marketing of highquality rice should be speeded up and scientific innovation should be promoted so as to provide technological support to the high-quality industry in Chongqing.
