Abstract: In order to clarify the appropriate cultivation model of rice variety Longjing 57,the glutinous rice variety Longjing 57was used as the test material,set two planting densities(20and 24holes·m^-2),and four nitrogen application rates(N0-0kg·ha^-1,N1-115kg·ha^-1,N2-138kg·ha^-1 and N3-161kg·ha^-1),to explore the effects of planting density and nitrogen application amount on the leaf area index,photometric combination,dry matter accumulation,yield and nitrogen utilization efficiency of the glutinous rice variety Longjing 57.The results showed that under the same planting density,the nitrogen fertilizer application amount had significant effects on leaf area index,photosynthetic potential,stem and sheath material output rate,panicles number,yield,and nitrogen use efficiency.As planting density increased,the leaf area index,stem and sheath material output rate,number of panicles,1 000-grain weight,yield and nitrogen use efficiency of Longjing 57improved in different degrees.Therefore,according to the characteristics of the variety,choosing the appropriate planting density and nitrogen application rate could exert the characteristics of the variety better,improve the light energy utilization and nutrient utilization efficiency,and obtain higher yields.Integrated yield index and nitrogen utilization efficiency,the suitable cultivation mode of Longjing 57was that the planting densities at 24holes·m^-2and the nitrogen fertilizer application rate at 115kg·ha^-1.
