摘要
为了探讨水稻不同穗形的增产潜力 ,力求在穗形、株型上有所突破 ,2 0 0 1年开展了 4个品系不同穗形高产栽培试验。试验结果表明 :直立穗形和半直立穗形理论产量水平均达 11775～ 12 0 5 0kg/hm2 ,比散穗形增产 1815～ 2 0 90kg/hm2 ,增产 18 2 %～ 2 2 7%,说明直立穗形和半直立穗形品种高产栽培产量潜力较大。
In order to research yield potential of rice varieties with different panicle type,we made an experiment in 2001.Field experiment proved that erect panicle and semi_erect panicle can attain a yield potential of 11 775～12 050 kg/hm 2,has a 18.2%～22.7% yield advantage over common panicle type.The result of cultivation showed that the yield potential of erect panicle and semi_erect panicle rice is higher than common panicle rice.
