Abstract:

To investigate the cultivation techniques of the high-quality early-maturing rice variety Zhongzu 18 in the coastal area of Taizhou，comparative experiments were conducted under different cultivation methods，planting densities，and nitrogen fertilizer levels，with the aim of summarizing a high-yield cultivation technical scheme for Zhongzu 18 in this region. The results showed that Zhongzu 18 had moderate tillering ability and small panicle size，so direct sowing was recommended to increase effective panicles. With a seed rate of 5-6 kg per 667 m2 and a pure nitrogen application rate of 12 kg per 667 m2，ideal effective panicle numbers and panicle size could be achieved，and the yield potential was significantly improved.

Key words: early rice, Zhongzu 18, early maturity, cultivation technique, direct sowing, high yield
