| 摘 要： | 通过对连作晚稻直播栽培不同品种、不同播种期的试验研究,提出了适合湖南省洞庭湖平原区连作晚稻直播栽培的品种有两优287、株两优30、株两优08等品种(组合),晚稻产量随播种期的推迟而降低,适宜播种期应控制在7月9-15日,如播种过迟,不利于晚稻安全齐穗,显著降低产量.

| Abstract: | The effects of varieties and cultivation techniques on late rice were studied.The results showed some continuous cropping late rice varieties were adaptable to the area of Dongting Lake plain in Hunan province,such as Liangyou 287,Zhuliangyou 30 and Zhuliangyou 08.The yield of late rice was decreased with the sowing date being delayed,and the experiment discovered that the best sowing date of late rice was from July 9 to July 15.The yield of late rice would decreased and the safety full heading would be aff... |
