为了给‘海花1号’在江苏及周边地区的推广种植提供栽培上的理论依据，通过单因素随机区组试验研究了不同施氮量对‘海花1号’产量和相关农艺性状的影响，同时用两因素随机区组试验分析了不同播种期及不同播种密度对其产量及构成因素的影响。结果表明：随施氮量的增加‘，海花1号’的产量表现为先增后降；适时的早播和适度的提高播种密度有利于其增产。因此，在江苏及周边地区种植，为获高产，每公顷施纯氮210 kg为宜，以300万/hm2至330万/hm2基本苗在10月28日至11月5日播种为佳。

To provide the theoretical basis of cultivation for‘Haihua1’in Jiangsu area, the effect of nitrogen fertilizer on yield and related agronomic traits of‘Haihua1’was studied with single factor randomized block design. Tow factors randomized block design trait was carried out to investigate the effect of seeding dates and sowing densities on the grain yield. The result showed that the yield of‘Haihua1’was ascend in first and descend at last with increased of nitrogen fertilizer. Proper early sowing and adequate sowing densities were conductive to improving the yield. In Jiangsu Province, the most appropriate nitrogen fertilizer, sowing densities and seeding date were pure nitrogen 210 kg/hm2, 300 million/hm2 to 330 million/hm2, October 28th to November 5th respectively.
