摘要
研究了播期与栽培密度对水稻(Oryza sativa L.)品种两优3313产量构成因子的影响。结果表明,两优3313在鄂西北地区适宜播期是4月中旬,在肥力水平中上等情况下栽插28.125万穴/hm^2最适宜。
The effects of sowing date and planting density on yield components of rice(Oryza sativa L.)variety Liangyou 3313 were studied.The results showed that the suitable sowing date of Liangyou 3313 in northwest Hubei province was the middle of April,and the planting density of 281250 holes/hm^2 was the most suitable under the condition of medium and high fertility level.
