Studies on the Pattern of Cultivating Rice for High Yield under Different Ecological Conditions in Liaoning Province TECHNOLOGY REPORT

Cultivars developed in recent years and imitations of mathematics and com- puters were employed to study on the technology of cultivating rice for high yield in main rice growing regions of Liaoning provinces. The regression Models for yield and yield components of representative cultivars and their cultivation technology for high yield were established according to the results. Analysis were also made on the adapta- tion of different cultivars to environments. the relationships between yield fluctuation and meteorological conditions, and differences of quality characteristics among geno- types and their relations with yield. In addition, the computer expert system for making a strategic decision. technology and trends in cultivating rice for high yield and high effi- ciency. good grain quality were determined for different rice growing regions.
