生育期及各个阶段间的时间长短对鉴定春小麦品种在具体栽培条件下的适应性具有重要意义。把春小麦品种按不同地理生态来源分组,以确认其每个栽培地区所特有的发育类型。旱地作物的生育特点决定于水、热因子的节奏性。在灌溉条件下,作物对降雨周期性的依
The duration of growth period and the length of each stage of the identification of spring wheat varieties under specific cultivation conditions adaptability is of great significance. The spring wheat cultivars were grouped according to different geo-ecological sources to confirm the developmental patterns unique to each cultivated area. The characteristics of dry land crops depend on the rhythm of water and heat factors. Under irrigated conditions, the crop regulates the periodicity of rainfall
