| 摘 要： | 不同播期试验结果表明,天优8012在浙江省作单季晚稻种植,5月20日至6月9日播种均可正常抽穗结实,但随着播种期的推迟,齐穗期、成熟期也相应推后。该组合千粒重和结实率较高,但必须掌握适宜秧龄才能实现高产稳产。在本试验条件下,以5月25日播种、秧龄35 d的处理单位面积产量和日产量较高,均极显著高于其他4个播期处理。

Effects of Sowing Date on Yield and Characteristics of Tianyou 8012 |
| |
| Abstract: | A field experiment was carried out to explore the appropriate sowing date of single season rice combination Tianyou 8012. The results showed that Tianyou 8012 is suitable for planting in Zhejiang Province for single late season rice. It can be normal head-ing and grain filling when sowing date from May 20th to June 9th. However, with the delay of sowing date, the full heading stage and maturity stage is also pushed back. Tianyou 8012 has high 1 000-grain weight and seed setting rate under appropriate seedling age. In this experiment, the yield and daily output of the treatment with May 25th sowing, 35d seedling age was significant higher than the other 4 treatments. |
