摘　　要：[目的]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]栽插密度27.0万~33.0万丛/hm^2,栽茎蘖苗54.0万~66.0万/hm^2,隆科16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。[Objective] To improve the unit yield level of rice in Longyang District, and to find the relationship between cultivated density and rice yield.[ Method] Under the condition of field plot test, effects of cultivated density on the yield and component factor were researched with Japonica rice Longke 16 as the test material.[Result] Under 270 000-330 000 clusters/hm^2 planting density and 540 000 -660 000/hm^2 tillers, the yield of Longke 16 reached 11 250-12 000 kg/hm^2 .[ Conclusion] Longke 16 is a high-yield Japonica rice variety with good com-prehensive traits.Rational cultivation and accurate planting can fully exert its potential of high yield.
