An experiment was performed in a sunflower field based on sunflower characters and relevant researches available to explore multiple-generation cultiva- tions in Hainan in order to establish a cultivation method of sunflower inbred line with three generations per year and reduce breeding process of inbred lines. The results showed that the cultivation site is chosen as per relevant standards that ef- fective accumulative temperature (≥5 ℃) is equal to or higher than 1 900 ~C within 110 d from sowing date. It is notable that a good choice of planting site is a guar- antee of the technology and to establish the method cultivating sunflowers with three generations per year is of great significance in terms of reducing breeding process of inbred lines and breeding costs. In addition to that, it provides refer- ences for rapid cultivation of multi-generation sunflowers and improving breeding effi- ciency. 展开更多

HUABEI Oilfield in the North China Plain beganto be explored in 1976. Its annual oil output hasbeen over 10 million tons for the past ten succes-sive years and it is ranked ninth amongst thenational enterprises handling oil and natural gas.During its 20-year construction, it was built to bea grand oil city. There are 110,000 emptoyeesincluding almost 40,000 women. It displaysfeatures of a modernized city when you walkthrough it-wide streets, office buildings, grass-land in inhabited areas, hospitals, schools, shopsand various recreation facilities. It takes on thehappy and auspicious atmosphere more than theimpetuousness of a big city On a mission to learnmore about the women working there, talked toHuang Lan, the committeewoman of the LaborUnion of Huabei Oil Administrative Bureau.
