黑龙江省春小麦是以主穗增产为主,分蘖利用率不高,传统的种麦模式无形之中增加了种麦成本,降低了种麦效益。结合近年来黑龙江省选育的春小麦优良品种,探讨春小麦稀植栽培的可行性。 1 材料与方法 1.1 试验设计根据品种类型的不同,选用龙辐10、龙麦26、东农122共3个品种;设600万株/hm~2、450万株/hm~2、300万株/hm~2、150万株/hm~2、75万株/hm~2 5个密度。采用
Spring wheat in Heilongjiang Province is dominated by the main spike yield and the utilization rate of tillers is not high. The traditional seed-wheat mode invisible increases the cost of planting wheat and reduces the benefit of planting wheat. Combining with the elite spring wheat varieties bred in Heilongjiang Province in recent years, the feasibility of sparse spring wheat planting was explored. 1 Materials and Methods 1.1 Experimental Design According to the different types of varieties, choose Longfu 10, Longmai 26, Dongnong 122 total of 3 varieties; set 6 million / hm ~ 24.5 million / hm ~ 23 million / hm ~ 21.5 million / hm ~ 2.75 million / hm ~ 25 density. use
