| 摘 要： | 目的]研究不同播期和栽插密度对天丰优084主要农艺性状及产量的影响。方法]设5月1、11、21、31日共4个播期，12万、18万、24万、30万、36万穴／hm^2共5个播种密度进行试验。结果]结果表明，天丰优084在苏南地区湿润育秧的合理播期为5月上中旬，不宜迟于5月下旬；在肥力水平中上的田块，天丰优084的合理密度为24万穴／hm^2。结论]为天丰优084大面积推广应用提供参考。

| Abstract: | Objective] The research aimed to study the effects of different sowing time and planting density on the main agronomic characters and yield of Tiangengyou 084.Method] Four sowing times were designed including May 1,11,21 and 31,and 5 planting density were designed including 12×104,18×104,24×104,30×104 and 36×104 per hectare.Result] The results showed that the reasonable sowing time of Tianfengyou 084 in southern Jiangsu Province was the first and second ten days of May,and should not be later than the third ten days of May.The reasonable planting density of Tianfengyou 084 was 24×104 per hectare in field with medium and upper fertility.Conclusion] The study can provide the reference for extending and applying Tianfengyou 084 in a large scale. |
