施种肥是小麦的重要增产措施之一.但有些生产单位,由于施肥品种、数量和方法不当,导致缺苗、断垅,得不到应有的增产效果,甚至减产.为此,我们于1980—1981年在车排于用春小麦进行了如下试验.供试肥料为尿素、硫酸铵、三料磷肥(含磷46%)、磷酸二铵(含磷46%、氮18%);施用量尿素;为每亩3、5、7、10、0(对照)公斤,硫酸铵为6.6、10.9、15.3、21.8、0(对照)公斤,三料磷肥为 3、7、10、15、0(对照)公斤,磷酸二铵为3、5、7、10、0(对照)公斤;
Fertilization is one of the important measures to increase wheat production, but some production units, due to improper quantity and methods of fertilization, result in lack of seedlings and broken fruits, The following tests were carried out on spring wheat from 1980 to 1981. The tested fertilizers were urea, ammonium sulfate, tricalcium phosphate (46% phosphorus), diammonium phosphate (46% phosphorus, 18% nitrogen) Urea; for each acre 3,5,7,10,0 (control) kg, ammonium sulfate 6.6,10.9,15.3,21.8,0 (control) kg, three fertilizer for the 3,7,10,15,0 ( Control) kg, diammonium phosphate 3,5,7,10,0 (control) kg;
