辽宁省不同生态条件水稻高产栽培模式研究技术报告

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

本项研究以数学模拟与计算机模拟为主要方法,以新品种为试材,研究了辽宁省主要稻作区的水稻高产栽培技术,建立了代表品种产量及产量构成因素的回归模型,确定了新品种的高产栽培途径,制定了与品种特性配套的高产栽培模式,分析了辽宁省水稻产量波动与气象条件的关系、水稻不同品种对环境的适应性、水稻品质性状的品种间差异及其与产量的关系,研制了计算机专家咨询系统,为各地区提出了水稻高产、优质、高效栽培的方向和技术措施。

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.
