摘　　要：采用裂区试验,对超级杂交早稻陆两优996进行了不同栽插密度(45.0万、30.0万、21.4万蔸/hm2)和基本苗(2,3,4苗/蔸)栽培试验,结果表明:不同栽插密度和基本苗对产量均有显著影响。在本试验条件下,超级杂交早稻陆两优996以插30.0万蔸/hm2,3苗/蔸,群体产量最佳。The split plot culture experiments with different planting densities（45.0×104,30.0×104,21.4×104 shoots/hm2） and basic seedling numbers（2,3,4 seedlings/shoot） were conducted to super hybrid early rice Luliangyou996.The results showed that different planting densities and basic seedling numbers all had significant impacts on yield.Under the experimental conditions in this paper,super hybrid early rice Luliangyou996 had the highest yield when planting density was 30.0×104 shoots/hm2 and 3 seedlings/shoot.
