摘要
本文采用环境分层,品种定位,分级固定,择优筛选,系统建模,辅之以多数唑和生长调节剂控长,促蘖,攻穗粒等方法,建立水稻栽培系统模型。89-92年,经大田验证,模型理论产量与实际产量的偏差未超过5%。信度均达0.95以上,表明模型具有较好的稳定性、为水稻生产进行科学系统管理、提供了可靠依据。
Asystanatic cultivation model for rice was estubtished in this study by stratifying the environments, using ,selected varieties, adjusting plant densities and fertilization rates, supplemented with MET and plant growth regulators. The model was tested form 1989 to 1992, It is showed that the deviation of the theoretical yield from the practical was less than 5%, the confidence level was over,0.95 This suggested that the model was higlh stable and could be a reliable basis for the scienlific and sytematic management in rice production.
