摘要
通过对布隆迪引进的中国水稻品种进行多年、多点生产试验,对参试水稻品种的产量及其构成等方面进行评价,为中国水稻品种在布隆迪大面积推广应用提供理论依据和技术指导。结果表明,中国水稻品种较当地品种表现出较高的产量水平,具有相对较好的适应性,且杂交稻品种相对常规稻品种增产效果显著;低海拔地区适宜种植杂交稻品种,而中高海拔地区适宜种植常规稻品种;水稻移栽相对条播和撒播产量更高,而节水栽培相对当地栽培模式增产效果明显。筛选出适宜布隆迪可大面积推广应用的水稻品种杂交稻特优649、常规稻桂丰2号,结合先进适宜的栽培技术有助于提高布隆迪水稻总体产量水平。
To provide theoretical basis and technical guidance for the popularization and application of rice varietiesintroduced from China,the yield and its components of rice cultivars were evaluated through multi-variety,multi-year and multi-point screening and identification tests in Burundi.The results showed that the yield of Chinese rice varieties was higher than that of local rice varieties,re⁃vealing that they had good ecological adaptability,and hybrid rice varieties had a significant effect on yield increase compared with conventional rice varieties.Hybrid rice varieties were suitable for planting in low-altitude areas,while conventional rice varieties were suitable for medium-high altitude areas.The transplanting rice had a higher yield than the rice using the drilling and broadcasting sow⁃ing technique.Meanwhile,water-saving cultivation had a higher yield than local cultivation in Burundi.Two rice varieties(hybrid rice Teyou 649 and conventional rice Guifeng No.2)suitable for the large-scale popularization and application in Burundi were screened out,and the overall rice yield level in Burundi could be further improved by combining with the advanced and appropriate cultivation methods.
