基本情况我县位于我省西部干旱地区,处于第二、三积温区划的交接地带。玉米生产上主要应用嫩单三号、嫩单四号、克单三号、克单四号四个单交种。它们是由五个低产自交系配制而成,制种以来多年平均制种亩产仅125,5斤。由于制种单产低、种子生产经济效益差、制种耗地多,农民不愿种,不仅严重影响玉米杂交种的推广普及,而且还直接影响我们种子公司的生产、经费和销售,成为企业的最大难题。
Basic situation I County is located in the western arid region of our province, in the second and third plot temperature zone of the transfer zone. Maize production mainly used tender single three, tender single four, gram single three, gram single four four single cross. They are made from five low-yielding inbred lines, and their annual average seed production has only been 125.5 kg per mu since seed production. Because of the low seed production per plant, the poor economic benefits of seed production, the high consumption of seed and the unwillingness of peasants to grow, it not only seriously affected the popularization of corn hybrids, but also directly affected the production, financing and sales of our seed companies and became the enterprises The biggest problem.
