玉米播种方式及合理密植的研究,前人已做过不少报导,但都着眼于大田生产,而对于玉米制种生产中自交系父、母本的种植方法及合理群体结构与制种产量相关性的研究则报导很少。我市种子公司积极探索玉米制种高产新的方法,在研究河北、山东等省对玉米制种父、母本种植方法改革的基础上,综合我市常规制种的特点,做了进一步的完善,将两年研究情况简结如下。

However, all of them focused on field production. However, the planting methods of parental and female parent in inbred lines of maize and the reasonable population structure and seed production Relevant research is reported very little. Our seed company actively explored the new method of producing high yield of maize seed. On the basis of studying the reform of planting methods of maize and maize in Hebei and Shandong provinces and other provinces, based on the characteristics of conventional seed production in our city, we made further improvement The two-year study is summarized as follows.
