国际水稻所的科学家们最近培育成功一种耐旱水稻新品种——IR13146。这种水稻不仅产量高,并且适应于在只靠降雨供给水源的干旱耕地上生长,而无需在灌溉田地里栽培,并具有很强的抵御病虫害的天然免疫力。在泰国、缅甸、孟加拉和印度等国的19个农业研究中心进行的试种表明,在无灌溉条件下,新品种水稻IR13146的产量每公顷仍接近4吨(约含每亩533斤),比相同条件下其它品种水稻的产量高的多。国际水稻所期望通过国家水稻种植计划尽快地将该新品种水稻推荐给农民种植,以考察经过数年大面积种植后的结果。 International Rice scientists have recently fostered the success of IR13146, a new drought-tolerant rice variety. This rice is not only high in yield but also suitable for growing on arid lands that supply water only by rainfall without cultivation in irrigated fields and has a strong natural immunity against pests and diseases. Tests conducted at 19 agricultural research centers in Thailand, Myanmar, Bangladesh and India showed that under non-irrigated conditions, the yield of the new variety IR13146 was still nearly 4 tons per hectare (about 533 kg per acre) Under the same conditions, other varieties of rice yield is much higher. IITA looks forward to recommending this new variety of rice to farmers as soon as possible through the national rice planting program to examine the results of large-scale planting over several years.
