老挝通过核技术提高水稻产量(图)
水稻产量 见稳定同位素技术 土壤科学家

大米是老挝人民民主共和国(PDR)的主要粮食作物,是粮食安全和就业的关键。全国80%以上的农民种植水稻,占全国耕地面积的60%左右。然而,老挝的山地地形、季风频繁的热带气候、土壤侵蚀、缺乏合适的水稻品种以及化肥使用不足限制了水稻产量,威胁着这个农业社会的生计。由于该国72%的水稻种植地区依赖于自然降雨,预计在不断变化的气候下日益变化的降雨模式将对水稻生产产生破坏性影响。

据最新一期《自然》杂志报道,加拿大萨斯喀彻温大学领导的国际团队在一项对全球小麦生产具有里程碑意义的研究——10+基因组计划中,对代表全球育种计划的15个小麦品种的基因组进行了测序。这将使科学家和育种人员能够更快地识别出具有影响力的基因,从而提高小麦产量、害虫抗性和其他重要的农作物性状。
种子特殊处理后更适应盐性土壤
种子 特殊处理 更适应 盐性土壤
2020/9/1
以色列SaliCrop公司找到一种创新的农作物培育方法,有望让大米、小麦、棉花等多种农作物在盐性土壤实现大规模商业化种植。该公司解决盐性土壤农作物生长的方法不是改造土壤,而是对种子进行特殊处理。其方法是在非常严格的条件下,用化学混合物液体浸泡种子,然后取出立即进行种植。不同配方的化学混合物液体用于不同品种的种子。液体中的化学物质决定了作物各种基因的行为。
