摘　　要：通过布置广两优96等杂交中稻的肥料试验,研究了不同施肥水平和施肥时间对其经济性状的影响。结果表明,高肥能使株高增高、最高苗和穗粒数增加,但对有效穗的增加和产量的提高作用不大。不同品种都有各自的不同施肥增产零界点,在生产栽培中,必须根据各个品种不同的需肥要求,制定不同的施肥方案。A fertilizer experiment was carried out on Guangliangyou 96 and other medium hybrid rice varieties to determine the effect of different fertilizer levels and fertilizer application time on economic traits.The result showed that high fertilizer could increase plant height,seedling and grain number,but could not increase panicle number and yield.Different varieties had different fertilizer-yield critical point.Therefore,fertilizer management should be conducted based on the fertilizer needs of different varieties.
