潜育化稻田品种耐潜性差异与栽培技术研究

The Research of Varieties Resistant and Cultivation Technique in Gleyed Paddy Soils

于2012年选取潜育化典型田块为试验田,研究了部分适合于长江中下游地区种植的早晚稻的耐潜性。结果表明,耐潜型的早稻品种为湘早籼45和金优458,敏感型的早稻品种为中嘉早17和湘早籼3号;耐潜型的晚稻品种为湘晚籼13,敏感型的晚稻品种为黄华占和天优华占。通过翻耕及垄畦栽培的方式可提高潜育化稻田水稻品种的有效穗数和每穗粒数,进而提高产量。

The tolerance of early season rice and late season rice in the typical gleyed paddy soils were studied in 2012 in Hunan province. The results indicated that the resistant early season rice were Xiangzaoxian 45 and Jinyou 458, the sensitive early season rice were Zhongjiazao 17 and Xiangzaoxian 3; the resistant late season rice was Xiangwanxian 13 and Jinyou 458, the sensitive late rice were Huanghuazhan and Tianyouhuazhan. Plowing and ridge cultivation could improve effective panicles, grains per panicle and yield of gleyed paddy rice.
