高寒坝区水稻长期适应高原生态条件,具有植株矮化、叶片变窄趋短、颖壳或稃尖现紫色而多毛或有芒等特征。由于整个生育期内温度偏低,因而高海拔水稻生育期及产量结构呈明显地区性的效应。简要阐述如下: (一)生育期延长,分蘖期推迟,分蘖率低 据丽江地区农科所及县农科所多年试验资料及1981和1982两年我们在丽江坝观察结果,
Alpine dam area rice long-term adapt to the ecological conditions of the plateau, with dwarfing plants, narrowing leaves shorter, husky or tip purple is present and hairy or other features. Due to the low temperature during the whole growth period, the growth period and yield structure of rice at high altitudes showed obvious regional effects. Briefly described as follows: (a) extension of growth period, delayed tillering, low tillering rate According to years of experimental data from the Agricultural Science Institute and County Agricultural Sciences in Lijiang Prefecture and our observation results in Lijiang dam in 1981 and 1982,
