为探究播期和秧龄对镉低吸收晚稻品种清莲丝苗产量及镉积累特性的影响,试验采用单因素随机区组设计,分别测定了6月19日、6月27日、7月5日3个播期和22、27、32 d 3个秧龄下的产量和镉含量。结果表明:(1)播期试验中,播期显著影响水稻产量...为探究播期和秧龄对镉低吸收晚稻品种清莲丝苗产量及镉积累特性的影响,试验采用单因素随机区组设计,分别测定了6月19日、6月27日、7月5日3个播期和22、27、32 d 3个秧龄下的产量和镉含量。结果表明:(1)播期试验中,播期显著影响水稻产量和镉含量,产量主要受每穗粒数和结实率影响,6月中下旬播种产量较高,7月上旬播种产量显著降低;早播处理显著降低植株各部位的镉含量;(2)秧龄试验中,各秧龄处理的产量无显著差异,适宜秧龄弹性较大;22 d秧龄处理各部位镉含量最低,32 d秧龄处理的糙米镉含量较低,但茎叶和谷壳镉含量较高。因此,建议清莲丝苗采用早播(6月中下旬)结合短秧龄(22 d)的栽培模式,可在稳产基础上充分发挥其降镉潜力。展开更多
