选用早熟、高产、稳产的玉米良种,是提高农业生产的有效措施。而任何良种增产潜力的发挥,有待于对该品种生育规律的了解程度和创造适宜的栽培条件,即所谓高产的途径必须是良种、良法配套。为保证北京地区玉米生产的持续高产,应该及时为生产上提供良种、良法。因此对比较有希望的新组合进行了初步观察,以供农业生产上参考。 Selection of precocious, high yield, stable yield of corn, is to improve agricultural production effective measures. However, the potential of all kinds of seed production to play, to be the understanding of the variety of reproductive laws and to create suitable cultivation conditions, the so-called high-yielding ways must be good seed, good law supporting. In order to ensure the continuous high-yielding corn production in Beijing, it is necessary to provide good seeds and good laws in time for production.
