摘　　要：以优质品种五优稻1号和超级稻品种松粳9号两个晚熟品种为试验材料,采用密度和品种裂区试验设计以及生化分析等方法,研究了不同插秧密度对碳氮代谢关键酶活性及产量的影响。结果表明,在M11(0.36m×0.15 m)密度条件下,优质品种五优稻1号ADPG(ADPG焦磷酸化酶)、GS(谷氨酰胺合成酶)活性表现较高;在M9(0.30 m×0.15 m)密度条件下,超级稻品种松粳9号ADPG、GS活性表现较高;在相应的条件(M11和M9)下,五优稻1号和松粳9号分别表现出较高的产量;这为相应密度条件下五优稻1号和松粳9号形成高产奠定了基础和提供了理论依据。Effects of transplanting density on yield and key enzyme activities of carbon and nitrogen metabolism of japonica rice in cold region were investigated by using of split plot design and biochemistry analysis.The results showed that the activities of glutamine synthase（GS） and ADP glucose pyrophos-phorylase（ADPGP） were different with cultivars and planting density.The activities of GS and ADPGP in high-quality cultivar Wuyou1 and super rice cultivar Songjing9 grains were higher under M11 and M9 density than the other density,respectively.Accordingly,higher yield could be presented in these two cultivars in the same conditions.The results provided a solid basis and theoretical proof for Wuyou1 and Songjing9 high-yield formation.
