杭锦后旗农科所按照内蒙推广站的布署安排,从本旗农业生产中存在的问题出发,在全旗范围内选择了六个点进行秋压碳铵田间试验。这六个点均选择在土壤肥力中等、地力均匀、地形开阔,有代表性的小麦茬地上进行。采用了秋压碳铵、春播前深施碳铵、开沟分期深施碳铵、分期表追碳铵、空白对照五个处理,2～3次重复,有机排列的单因子试验。在试验田的管理上,严格掌握碳铵施用方法,其它措施(品种、播种方法、中耕、浇水、收获)均一致。
Hangjinhouqi Agricultural Science and Technology Department in accordance with the arrangement of Inner Mongolia promotion station arrangements, from the existing problems in agricultural production in the flag, the entire range of the selected six points for autumn under pressure ammonium bicarbonate field trials. These six points are selected medium fertility in the soil, uniform fertility, open terrain, the representative of the wheat stubble on the ground. Acupoint Acupoint was used in the experiment. Ammonium compaction was applied during autumn, ammonium bicarbonate was applied prior to sowing, ammonium bicarbonate was deep-seated in open ditch stage, followed by five cycles of ammonium bicarbonate and blank control. In the management of experimental fields, the application of ammonium bicarbonate was rigorously controlled. Other measures (varieties, sowing methods, cultivating, watering and harvesting) were consistent.
