摘要:

为筛选适合东莞乃至华南地区种植的观赏性佳、抗性强、产量高、性状稳定的彩色稻品种,引进14个紫色叶片的彩色稻品种进行早晚造种植试验,在全生育期调查记录叶色、株高、抗倒性、产量等农艺性状,进行同品种早晚造及品种间比对、分析。结果表明,同一品种在早造、晚造的叶色、生育期、株高、产量都有明显差异;14个彩色稻品种(系)间叶色和农艺性状也有显著差别,综合各个性状研究分析,筛选出分别适合早造、晚造种植的彩色稻品种。早造最优推荐为‘省紫’、‘花紫’、‘优紫’和‘紫叶红米’,其次是‘杭紫’、‘坚紫2号’、‘矮紫’和‘英紫’;晚造最优推荐为‘省紫’、‘花紫’和‘优紫’,其次是‘坚紫2号’、‘矮紫’、‘英紫’、‘紫叶红米’、‘江紫1号’、‘江紫2号’和‘紫红1号’;颜色最为好看的是‘英紫’,但它存在植株比较矮小、产量低等问题,为了“稻田画”图案的美观,可以选择小范围应用。研究可用于指导“稻田画”的制作用种,促进美丽乡村建设与粮食丰收,推动湾区都市高品质发展。

Abstract:

To select colored rice varieties with good ornamental value, strong resistance, high yield, and stable characteristics, and are suitable for “rice planting” in Dongguan and even South China region, 14 colored rice varieties with purple leaves were introduced to carry out the early and late planting trials. The agronomic traits such as leaf color, plant height, lodging resistance and yield were investigated and recorded during the whole growth period. These data were used for the comparative analysis between early and late planting of the same variety or among different varieties. The results showed that there were significant differences in leaf color, growth period, plant height, and yield between early and late planting period of the same variety. There were also significant differences in leaf color and agronomic traits among 14 colored rice varieties. According to the analysis of various characters, the colored rice varieties suitable for early and late planting were selected. The most recommended varieties for early production are 'Shengzi', 'Huazi','Youzi' and 'Ziyehongmi', followed by 'Hangzi', 'Jianzi No.2', 'Aizi' and 'Yingzi'. The most recommended varieties for late production are 'Shengzi', 'Huazi', and 'Youzi', followed by 'Jianzi No.2', 'Aizi', 'Yingzi', 'Ziyehongmi', 'Jiangzi No.1', 'Jiangzi No.2', and 'Zihong No.1'. The color of 'Yingzi' is the most beautiful, but due to its problems such as relatively short plants and low yields, the variety only can be planted small scale for the beauty of "paddy field paintings". The results can be used to guide the variety selection for "paddy field paintings", and promote the construction of beautiful countryside and grain harvest, and the high-quality development of the Greater Bay Area cities.
