摘要
本文采用模糊数学原理,根据与春化阶段密切相关的播种至拔节日数、总生育日数、抗寒性和产量等性状的表现和差异,将全国供试的31个品种进行了生态类型的分类。并根据小麦不同生态类型的特点,讨论了适合山东种植的生态型品种及引种地区。试验指出,半冬性、冬性品种适宜在山东秋播种植;所有春性品种均不宜在山东秋播。
Using Fuzzy method, the authors classified 31 wheat varieties into some ecological groups based on differences in the characteristics closely related to vernalization, which include the days from sowing to jointing stages, total days to maturity, freeze resistance and grain yield.The varieties suitable for growing in Shandong and the geographical zones suited to be introduced to Shandong are discussed here,The study showed that winterness and halfwinterness varieties are suitable for autumn sowing and all springness varieties could not be planted in autumn in Shandong.
