2011—2012年在湖南长沙以超级杂交稻Y两优1号、杂交稻汕优63和常规稻黄华占为材料的大田定位试验,比较了垄作梯式栽培技术(两种垄规格)和垄厢栽培技术(3种厢规格)对水稻产量和根系性状的影响。与平作栽培(T0)相比,窄垄作梯式栽培(T1)和垄厢栽培(T3)均可提高水稻产量,其中以T1的产量最高,比T0平均增产22.2%(17.1%~27.2%),其次T3平均增产10.4%(5.8%~15.0%),但随着垄宽或厢宽的增加,产量增幅逐渐下降。较高的穗数和每穗粒数、良好的根系特性(根系氧化力、根表面吸收面积、根系孔隙度)以及齐穗后干物质积累量大是上述两种栽培技术增产的重要原因。同时,根解剖结构表明垄作梯式栽培的根皮层减小、中...

A field experiment was conducted in Changsha city of Hunan Province in 2011 and 2012 to find out a cultivation technique of ridge & terraced cultivation (RTC) for improving rice yield and root trait. Super hybrid rice Yliangyou 1, hybrid rice Shanyou 63 and conventional rice Huanghuazhan were used in the mid-rice season. The cultivation patterns were designed as ridge & terranced cultivation (T1, ridge width 60 cm; T2, ridge width 120 cm), bed cultivation (T3, bed width 70 cm; T4, bed width 140 cm; T5, bed width 230 cm), and traditional cultivation (T0). The characteristics of grain yield form...
