摘要 通过在水稻上实施沟台栽培方法试验结果表明,沟台栽培方法有利于改善水稻的生长环境、促进分蘖、增加有效分蘖、提高成穗率,并有利于节水。试验得出,台上插2行方法最优。台上插2行较对照增产704.42kg/hm^2,达9.74%,提高氧化还原电位61.3mv,有效穗数增加4.2个,成穗率提高10.6%。 In this paper, rice furrow culture methods were studied. The result showed that the methods were beneficial to increase production, to improve conditions of rice growing, to promote tiller, to increase effective tiller and the percentage of earbearing tiller, and to save water. Planting 2 rows on the platform was the best. It increased the yield by 704. 42kg/hm2 which was 9.74% higher than that of control. It increased the soil oxidation- reduction potential by 61.3 mv and increased percentage of earbearing tiller by 10.6 %, The number of effective panicle increased by 4.2.
