为了探究湖南地区机插杂交稻在不同基本苗配置与施肥量下的产量与干物质生产表现,2016年在湖南宁乡以杂交稻品种隆两优1212和隆两优华占为材料,进行了大田试验。试验设置了3个施肥水平(500、900、1400kg/m~2)和4个基本苗组合(28.6万丛/hm~2+单本/丛、23.5万丛/hm~2+单本/丛、23.5万丛/hm~2+双本/丛、19.0万丛/hm~2+双本/丛)。试验结果表明,施肥量对产

In order to explore the effects of different seedlings combination and fertilizer application on yield and dry matter production of machine-transplanted hybrid rice, a field experiment was conducted with Longliangyou 1212 and Longliangyou huazhang as materials. There are three fertilization levels, including F1 （500 kg/hm2）,F2 （900 kg/hm2） and F3 （1 400 kg/hm2） and four seedlings combination, including D1（28.6 hill/m2 with one seedling per hill）, D2（23.5 hill/ m2 with one seedling per hill）, D3（23.5 hill/m2 with two seedlings per hil...
