摘要
根据春小麦的分蘖消长规律和叶蘖同伸关系.将春小麦不同类型品种(系)进行了调查研究.结果表明:早熟、特早熟品种(系)分蘖发生早.低位分蘖发生快,分蘖发生经历的时间短,分蘖消亡经历的时间长,主茎3、4、5片叶叶蘖发生符合同伴关系;而中熟、中早熟品种(系)分蘖发生较晚.分蘖消长的时间相当,叶蘖同伸情况与理论值吻合程度较差.这将为今后在农业生产中因春小麦品种类型不同而采取相应栽培管理措施提供理论依据.
Based on the tiller emerging law and co-elongationrelation of leaves and tillers of spring wheat, different varieties ofspring wheat were investigated and studied. The results are as follows: To early and very-early maturing varieties, tillering happened earlyand tillering in the lower part hapened quickly, and it took shortertime in tillering emergence and longer time in extinction . The emergenceof leaves and tillers of the third, fourth, and fifth leaves on themain stem accorded with co-elongation law. However, to mid-maturing andmid-early maturing varieties, tillering happened much later andtillering emergence and extinction took nearly the same long time . Theco-elongation of leaves and tillers didn't accord with the law. Theseresults offer a theretical foundation for applying different methods ondifferent varieties of spring wheat.
