Abstract:

After 2 years of trial planting and demonstration, the yield targets of 900-1 000 kg/667 m² （for middle rice） and 800 kg/667 m² （for post-tobacco rice） of Zheyou 21 were achieved in the northern Fujian rice area. This paper summarized the high-yield characteristics and key techniques of machine-transplanted cultivation of Zheyou 21 as middle rice and post-tobacco rice.

Key words: indica-japonica hybrid rice, Zheyou 21, medium rice, post-tobacco rice, high-yielding cultivation techniques

摘要：

经2年的试种示范，在福建省闽北稻区实现了浙优21作中稻机插栽培单产900~1 000 kg/667 m²和烟后稻机插栽培单产800 kg/667 m²的目标。本文总结了浙优21作中稻和烟后稻机插栽培的高产特性及关键技术。
