采用水、旱两种方式栽培25个云南陆稻品种。对主要农艺性状和光合速率,气孔阻抗,水势等观察测定,结果表明云南陆稻在南京表现耐旱适应性较差。与水、陆稻对照品种南粳34和南通陆稻比较,它们属于不典型陆稻或偏水型陆稻。只有在水栽条件下才能充分发挥其大穗大粒的有利经济性状。
Using water, drought two ways to cultivate 25 Yunnan Upland rice varieties. The main agronomic traits and photosynthetic rate, stomatal impedance, water potential and other observations were measured, the results showed that Yunnan Upland rice in Nanjing drought tolerance less. Compared with the rice landraces, Nanjing 34 and Nantong, the landraces belong to the atypical upland rice or the partial upland rice. Only in the hydroponic conditions can give full play to the beneficial economic traits of large ears big grain.
