浙粳99是浙江省农业科学院作物与核技术利用研究所与浙江勿忘农种业股份有限公司合作选育的单季常规晚粳稻品种。该品种连续5年被列入浙江省主导品种,并多次刷新“浙江农业之最”单季常规晚粳稻百亩方和攻关田高产纪录。通过考查测产田块的穗粒结构和调查攻关田的施肥情况,分析了浙粳99获得超高产的特征特性及其关键栽培技术。浙粳99超高产栽培技术为：培育短龄壮秧、适当密植、科学肥料运筹和水浆管理。

Zhegeng 99 is a single-season conventional late japonica rice variety, bred jointly by the Institute of Crop and Nuclear Technology Utilization of Zhejiang Academy of Agricultural Sciences and Zhejiang Wuwangnong Seed Industry Co., Ltd. This variety has been listed as the leading variety in Zhejiang Province for five consecutive years, and has repeatedly set the high-yield record of the single-season conventional late japonica rice in the “the best of Zhejiang agriculture” campaign. By investigating the panicle-grain structure of Zhegeng 99 and the fertilization situation of the key field, the characteristics of Zhegeng 99 and its key cultivation techniques for obtaining super high yield were analyzed in this study. Finally, the super high-yield cultivation technology of Zhejing 99 was proposed.
