栽培密度对水稻产量及食味品质影响的相关性研究

Studies on the Effect of Cultivation Density on Yield and Edidle Quality of Rice

在低氮肥条件下,栽培密度对寒地水稻产量性状及食味品质的影响研究表明:产量与有效穗数呈极显著正相关,与穗长呈显著负相关,与粗蛋白含量呈显著负相关,与直链淀粉含量呈显著正相关;有效穗数与株高呈显著正相关,与穗长呈负相关,与粗蛋白含量呈显著负相关,与直链淀粉含量呈显著正相关;粗蛋白含量与直链淀粉含量呈显著负相关。在本试验条件下,水稻的农艺性状及食味品质间差异显著,栽培密度处理4在稻谷高产量的基础上,改善了稻米的食味品质,从而为提高寒地水稻食味品质的高产、优质栽培提供理论依据和技术参考。

Under low N condition, the effect of cultivation density on yield and edible quality of rice showes that yield is significantly negatively related with effective panicle number, positively related with length of panicle and rough protein content that effective panicle number is significantly positivly relatad with plant heiglt and amylose content negalively related with lengh of panicle rough protein content that rough protein content is significantly negatively relatad with amylose content. Under the experiment condition, there is great differene between agronomy characteristic and edible quality. Treatment 4 is fit both to yield and edible quality.
