进入90年代,随着大穗型良种的不断育成,大穗型小麦推广种植面积迅速扩大。大穗型小麦品种虽然存在难攻穗数和后期千粒重受气候因素影响较大等缺点,但以其高抗倒伏,易于小麦联合收割机作业;后期群体小,便于夏玉米套种;增产潜力大,适于高产栽培等优点,得到广大农民的喜爱。大穗型小麦在所需地力、基本苗、种植规格及田间管理等方面与传统的多穗型小麦具有明显的不同,要获得理想的产量与效益,需实行与大穗型小麦生产特性相适应的高产配套栽培技术。
Into the 90’s, with the continuous breeding of large-spike varieties, large-spike wheat planting area expanded rapidly. Although the big spike wheat varieties have the disadvantages of difficult spike panicles and the 1000-grain weight heavily influenced by the climate factors at the later stage, they are easy to combine with the wheat combine harvester because of their high resistance to lodging and small population at the later stage, Suitable for high yield cultivation, etc., get the love of the majority of farmers. Large-spike wheat is obviously different from traditional multi-spike wheat in terms of required soil fertility, basic seedling, planting specifications and field management, etc. In order to obtain the ideal yield and benefits, it is necessary to adapt to the production characteristics of large-spike wheat High-yielding cultivation techniques.
