摘　　要：用粳型巨胚稻新品系西巨胚1号为试验对象,以常规粳稻‘合系22-2’作对照,采用淹水、旱种和垄畦等三种栽培方式进行种植,研究不同栽培方式对粳型巨胚稻产量和品质的影响。结果表明:巨胚稻的穗粒数和有效穗受栽培方式的影响较大,与产量的相关性大,采用垄畦栽培可以获得比淹水和旱作都高的产量;栽培方式对巨胚稻米的外观形状、糙米率、蛋白质和直链淀粉含量等影响不大,但对垩白粒率和垩白面积影响较大。因此,在巨胚稻生产过程中建议采用垄畦栽培以获得最大产量和最优品质。The experiment studied the three different cultivation regimes of submerged irrigation,dry cultivation and ridge cultivation used the Japonica Xi-giant embryo-1 as experimental material,conventional japonica rice＇Hexi-22-2＇as control.The grain yield and quality of Japonica Giant Embryo rice were studied under three different cultivation regimes.The results indicated that the significantly promoted effective panicles and spikelets per panicle were greatly influenced by cultivation regimes,which were correlated with yield,so the grain yield of the ridge cultivation was higher than that of the submerged irrigation and dry cultivation.The influence of different cultivation regimes to rice appearance,brown rice rate,protein content and amaylose content of Japonica Giant Embryo rice were not obvious,but to the percentage of chalky grain and chalkiness area of Japonica Giant Embryo rice were obvious.Therefore,ridge cultivation was the most beneficial cultivation regime to obtain the highest grain yield and the greatest income.
