西宁位于青藏高原东北部,海拔近2300米,气候情况与外省甜菜产地区别较大。为了在这里开展甜菜育种繁种工作提供理论依据,我们在东北农学院董一忱教授的提议和指导下,对甜菜开花习性进行了初步观察。方法在开花前,选择生长正常有代表性的种株(多枝型、混合型、单枝型各2株)六株,进行定株砚察。从六月二十五日开始到八月九日结束。根据开花情况,每株观察30— Xining is located in the northeastern Qinghai-Tibet Plateau, an altitude of nearly 2300 meters, the climate and the provinces beet production differ greatly. In order to provide a theoretical basis for carrying out the breeding of sugar beet here, we have conducted preliminary observations on the beet blossom habits under the guidance and guidance of Professor Dong Yichen of Northeast Agricultural College. Methods Before flowering, six representative strains of plants with normal growth (2 branches, 2 branches and 2 branches) were selected for stanza screening. From June 25 until August 9. According to flowering, each plant observed 30-
