摘要： 为进一步研究与探索杂交水稻新组合D优3138合理的种植密度，设计了6种不同插植密度试验。结果表明，D优3138在密度为18.75万丛/hm2时产量最高，与7.50万丛/hm2、11.25万丛/ hm2及26.25万丛/hm2处理的差异达极显著水平。

Abstract: In order to study and explore the reasonable planting density of new hybrid rice combination D-You 3138, 6 different transplanting densities were designed. The results showed that the yield was the highest when the density was 187 500 /hm2, and has significant difference with 75 000 /hm2, 112 500 /hm2 and 262 500 /hm2 treatments.

Key words: hybrid rice, planting density, economic traits, yield
