Abstract:

The conventional early indica rice variety Zhongzu 100 has the characteristics of excellent plant type, strong tillering ability, high seed setting rate, strong resistance, and high yield. In 2024, this variety created a new historical record for early rice yield in Zhejiang's research field with a yield of 11.32 t/hm2, 0.10 t/hm2 higher than the previous highest yield record (11.22 t/hm2) achieved by Zhongzao 39 in Zhuji County in 2016. At the same time, the yield of 11.25 t/hm2 in the hundred-mu demonstration plot of early rice also broke the record for the “Peak of Zhejiang Agriculture”. This article introduced the characteristics of achieving super-high-yield of Zhongzu 100 and elaborated on the key cultivation techniques for achieving breakthroughs in high yield of Zhongzu 100.

摘要：

常规早籼稻品种中组100具有株型优良、分蘖力较强、结实率高、抗病性强、丰产性好等特点。2024年该品种在江山创造了单产11.32 t/hm2的浙江早稻攻关田历史纪录，比2016年中早39在诸暨创造的攻关田最高产量纪录（11.22 t/hm2）高0.10 t/hm2。同时，百亩攻关方单产达11.25 t/hm2，刷新了“浙江农业之最”早稻百亩方最高单产纪录。本文介绍了中组100获得超高产的特征特性及关键栽培技术。
