| 摘 要： | 目的]研究不同播期对水稻秧苗素质的影响,为确定晚季的最佳播种期提供理论依据。方法]通过对3个水稻品种6个不同播期情况下生长的秧苗的地上部和地下部性状调查,确定双季晚稻最佳播种时期。结果]第1叶鞘高与第2叶长呈极显著的正相关,且他们的二次拟合方程具有很好的拟合性。3个水稻品种的不同播期对地上部和地下部的影响都有显著差异。结论]初步确定广东地区双季晚稻品种天优428的最佳播种期在6月25 ~7月2日,天优998和玉香油占晚季的最佳的播种期在7月2 ~9日。

| Abstract: | Objective] The aim was to study seedling quality of rice sowed at different dates so as to provide theoretical basis for determining the best seeding time.Method] By investigating the characters of shoot and root of different varieties sowed at different dates,the best seeding time of double-cropping late rice was determined.Result] The first leaf sheath height and the second leaf length shared significantly positive correlation,which fit the quadratic equation well.The effects of different sowing dates ... |
