摘　　要：[Objective] This study was conducted to improve unit yield of rice in Longyang District and find the relationship between transplanting density and rice yield. [Method] Under the condition of field plot test, effects of cultivation density on yield and yield components were investigated with japonica rice Longke 16 as a test material. [Result] Under a planting density of 2.7-3.3×10^5 clusters/hm^2, equivalent to a density of seedlings with tillers of 5.4-6.6×10^5/hm^2, the yield reached 11 250-12 000 kg/hm^2. [Conclusion] Longke 16 is a japonica rice variety with good comprehensive characters, and rational dense planting and accurate quantitative cultivation could give full play to its high yield potential.[目的]为提高隆阳区水稻单产水平,明确栽插密度与水稻产量的关系。[方法]在田间小区试验条件下,以粳稻隆科16为材料,采用不同栽插密度研究对其产量及构成因素的影响。[结果]结果表明,栽插密度2.7~3.3×10~5丛/hm^2,栽茎蘖苗5.4~6.6×10~5/m^2,产量可达11 250~12 000 kg/hm^2。[结论]隆科16是综合性状好的高产粳稻品种,合理密植,精确定量栽培,可以充分发挥其高产潜力。
