随着我国经济和科学技术的快速发展,我国农业发展取得了显著的成就。在整个国民经济发展中,农业所占比重逐渐增大,且农业在国民经济发展中起着重要的作用。在我国农业实际发展过程中,玉米得到了广泛的应用和推广,是主要的粮食作物之一,由于各地区气候条件存在差异,决定了不同生态地区需采用不同的玉米品种。通过对我国河北省秦皇岛地区的气候和生态环境进行调查和分析,由于其特殊性,比较适合种植丹玉405玉米。基于此,对秦皇岛地区丹玉405杂交种的引种情况和种植表现进行分析,并介绍了丹玉405杂交种的种植与栽培技术要点。
With the rapid development of economy and science and technology in our country, remarkable progress has been made in the development of agriculture in our country. In the entire national economy, the share of agriculture is gradually increasing, and agriculture plays an important role in the development of the national economy. In the actual development of agriculture in our country, corn has been widely used and popularized. It is one of the main food crops. Due to the difference of climatic conditions in different regions, it is decided that different maize varieties should be adopted in different ecological regions. Through the investigation and analysis of the climate and ecological environment in Qinhuangdao of Hebei Province in our country, it is more suitable for growing Dan-jen 405 corn due to its particularity. Based on this, we analyzed the introduction and cultivation of Dan-jen 405 hybrid in Qinhuangdao, and introduced the main points of cultivation and cultivation of Dan-jen 405 hybrid.
