为了缩短冬小麦育种年限,加快育种进程,我们在连续两年麦收后试验复种墨西哥春麦成功的启发下,进行了冬春小麦杂交一代就地夏播加代实验。一、我县的地理气候要素我县地处西北黄土高原丘陵沟壑区,位于甘肃省东部,北纬36°,东径105°,海拔约1200米,年平均气温7.6℃,无霜期164天,年平均降水量516公厘。二,试验情况
In order to shorten the breeding period of winter wheat and accelerate the breeding process, we carried out the in-situ summer sowing-plus-generation experiment of the winter-spring wheat hybrid generation under the success of two consecutive years of post-harvest trial of double crop Mexican spring wheat. First, the county’s geographical and climatic factors My county is located in the hilly area of Northwest Loess Plateau, located in the eastern Gansu Province, 36 ° north latitude, 105 ° east diameter, about 1200 meters above sea level, the annual average temperature of 7.6 ℃, frost-free period of 164 days, the average annual 516 millimeters of precipitation. Second, the test situation
