摘要
在广西罗城县中稻地区开展超级稻—再生稻不同栽培密度试验研究,结果表明：抛栽密度为18万~21万蔸/hm2,穗粒结构较合理,头季稻与再生稻一年两季收获的稻谷产量较高,宜示范推广。
In Guangxi Luocheng eouty,influence on field different planting density of super rice ratooning rice experinent study was carried out, the result showed that,the most rational construction of grain comes within 180 000 to 210 000 hills each hectare beeanse the produetion peak appears on two harvests a year of the season flee--ratooning flee,and it is suitable for extention.
