“宁麦８号”系江苏省农科院选育的矮秆、抗倒的高产小麦品种。１９９７年引进，大灾之年仍取得单产２６０ｋｇ左右，比大面积增产３６．８％。为进一步了解和明确“宁麦８号”大面积条件下对肥料和密度的反应，我们于１９９８～１９９９年度进行了本试验。１材料与方法１．１ “Ningmai 8” Department of Jiangsu Academy of Agricultural Sciences breeding dwarf, anti-down high-yield wheat varieties. Introduced in 1997, the catastrophe still achieved about 260kg per unit yield, 36.8% larger than the large area. In order to further understand and clarify the response of fertilizer and density to a large area of ​​“Ningmai 8”, we conducted this experiment in 1998 ~ 1999. 1 Materials and Methods 1.1
