中组53是中国水稻研究所选育的高产早籼稻新品种，于2020年通过浙江省农作物品种审定委员会审定。该品种具备生育期较早、株型适中、分蘖旺盛、穗大粒多、高产潜力大等特点，适宜在浙江省及具有相似生态条件的区域作早稻种植。在2021年和2022年超级稻百亩方测产验收中，中组53平均产量分别达到10.26 t/hm²和9.90 t/hm²， 2023年被农业农村部认定为超级稻品种。中组53于2017年引入江山市种植，现累计种植面积已经超过3 333.33 hm²， 2023年种植面积占比超过38.00%，已成为江山市早稻主推品种。本文介绍了中组53在江山市区域试验、展示及示范的种植表现及主要农艺性状，归纳总结了其高产栽培技术，旨在为进一步促进中组53在江山市及类似区域的推广种植提供参考。

Zhongzu 53, which is an early-season indica rice variety with high yield, was bred by China National Rice Research Institute and was approved by the Zhejiang Crop Variety Approval Committee in 2020. It is suitable for planting in Zhejiang Province and similar ecological regions as it has the characteristics of early maturity, moderate plant architecture, high tillering ability, large panicle with high grain number, and high yielding potentials. The average yield of Zhongzu 53 reached 10.26 t/hm² and 9.90 t/hm² in the large-scale demonstration of super rice in 2021 and 2022, respectively. It was subsequently identified as a new super rice variety by the Ministry of Agriculture and Rural Affairs in 2023. Zhongzu 53 was introduced to Jiangshan County for planting in 2017. It has become the main variety in Jiangshan as its production area accounted for more than 38% in 2023 and its cumulative production area has exceeded 3 333.33 hm² in 2023. This paper introduced the planting performance and summarized the key high-yielding cultivation techniques of Zhongzu 53 in Jiangshan County in the last few years, which provided guidance for further promoting the cultivation of Zhongzu 53 in Jiangshan and similar area.
