摘　　要：针对超级杂交粳稻组合辽优1052的特征特性,在中等土壤肥力的条件下,进行了肥力与密度及不同栽插规格的试验研究,通过试验初步得出:施标氮900 kg/hm2时,以30 cm×13.2 cm或30 cm×16.5 cm的栽植密度较为适宜。施氮1 200 kg/hm2与900 kg/hm2,其产量差异不显著,而且随施氮量的增加,稻米的品质下降。在插秧规格的试验中以均匀分布的产量最高,平均产量超过了11 250 kg/hm2。According to the traits and chracteristics of super Japonica hybrid rice Liaoyou1052, the studies were made by different amounts of fertilizer application and defferent transplanting densities under middle - fertility soil. The experimental results showed that it was suitable under the densities of 30 cm × 13.2 cm and 30 cm × 16.5 cm by applying standard nitrogen 900 kg/hm^2. It was not significant for the difference between applying standard nitrogen 1 200 kg/hm^2 and 900 kg/hm^2. With increment of nitrogen application , the rice quality got lower. In the another experiment, the yield was highest by even distribution of transplanting, average yield exceeding 11 250 kg/hm^2.
