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。
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.
