摘要: 采用二次正交旋转组合设计方法,选择栽培密度、行距2个可控因子进行巨型稻丰超6号高产栽培模式研究,同时观察记载田间温光差异。经过对实际产量与因子间的数学模型分析,得出巨型稻单产达到9 000 kg/hm2以上的2个因子水平配置为栽培密度86 064~92 880株/hm2,行距43.94~50.78 cm。

关键词: 巨型稻, 栽培密度, 株行距, 产量

Abstract: Through the quadratic general rotary unitized design to study the high-yield cultivation mode of giant rice Fengchao No.6,two controllable factors of cultivation density and row spacing was selected, and the temperature and light difference in the field was recorded. Analyzing the mathematical model between actual yield and two factors, it is concluded that the two-factor level configuration with a yield of more than 9 000 kg/hm2 is cultivation density 86 064~92 880 plants/hm2, row spacing 43.94~50.78 cm.

Key words: giant rice, cultivation density, row spacing, yield
