摘 要: | 以辽阳地区3个生育类型的6个常规粳稻品种为试验材料,连续3年(2015年至2017年)研究旱直播稻作方式对水稻生育期表现及产量的影响。结果表明,在辽阳地区进行旱直播水稻栽培,黑龙江省晚熟早粳水稻品种抽穗期提前且产量最低,吉林省早熟中早粳水稻品种抽穗期适中且产量最高,辽宁省中熟中早粳水稻品种抽穗期延后且产量较高。从安全抽穗和产量综合考虑,辽阳地区旱直播稻宜选用吉林省早熟中早粳水稻品种。 |

Abstract: | A field experiment was carried out with six japonica rice cultivars of three growth-development types adopted in Liaoyang region, to study the effects of cultivation methods of dry direct-seeding rice on the growth stage performance and rice yield for 3 consecutive years (2015-2017). Results showed that dry direct-seeding rice was cultivated in Liaoyang region, late-maturity early japonica varieties of Heilongjiang province had the heading stage advanced and the lowest yield. Early maturity mid-early japonica varieties of Jilin province had a moderate heading stage and the highest yield. Medium maturity mid-early japonica varieties of Liaoning province had heading stage delayed and the higher yield. The early maturity mid-early japonica varieties of Jilin province was suitable for cultivation method of dry direct-seeding rice in Liaoyang region in comprehensive consideration of heading safely and high yield. |
