秀水04是由浙江省嘉兴市农科所选育的晚粳新品种。1984年参加苏州市单季晚粳新品种(系)引种鉴定试验,1985～1986年参加江苏省单季晚粳稻品种区域试验,1986年参加江苏省单季晚粳稻品种丰产性辅助试验,表现丰产、稳产,抗性突出。1987年3月经江苏省农作物品种审定委员会审定通过,适宜于太湖地区东南部中上等肥力条件下种植。目前,已在苏州市的吴县、吴江县、昆山县大面积种植,并已成为本市单季晚粳的主栽品种。为了更好地发挥秀水04的增产效能,现根据试验资料进行其丰产性、稳产性分析,并据此提出高产栽培途径,为大面积高产提供科学依据。 (一)丰产性:秀水04属中熟晚粳型品种,比同类型的品种具有更高的丰产性。据1984 Xiushui 04 is a new japonica variety selected by Jiaxing Agricultural Science Institute in Zhejiang Province. In 1984, he participated in the introduction and identification test of new varieties of late japonica single seasons in Suzhou City. From 1985 to 1986, he took part in the regional experiment of single-season late japonica rice varieties in Jiangsu Province. In 1986, he joined the single-season late japonica rice varieties high yield auxiliary test in Jiangsu Province, , Stable yield, outstanding resistance. March 1987 approved by the Jiangsu Provincial Crop Variety Approval Committee, suitable for cultivation in southeastern Taihu Lake region under the conditions of fertility. At present, it has been planted on a large area in Wu County, Wujiang County and Kunshan County, Suzhou City, and has become a major cultivated variety of late japonica rice in this city. In order to give full play to the yield increasing efficiency of Xiushui 04, the analysis of its high yield and stability is based on the experimental data and the high-yield cultivation methods are put forward to provide a scientific basis for large-area and high-yielding. (A) high yield: Xiushui 04 is a late-maturing japonica varieties, than the same type of varieties have a higher yield. According to 1984
