谷子是我省主要栽培作物之一,但七十年代以后,由于多种原因,播种面积大幅度下降。近年来,播种面积又逐步得到恢复和发展,生产条件有了改善,生产水平也不断提高。如何在较高的肥、水条件下确定谷子栽培的适宜密度,以便充分发挥其增产潜力,获得更高的产量,这是目前生产上迫切需要解决的一个重要课题。为此,我们于1981～1983年,在沈阳农学院校内试验地连续进行了三年谷子高产群体结构试验。从而了解和掌握群体结构发展动态的规律,研究群体与个体,地上部与地下部,营养器官与生殖器官,前期与后期健全而协调地发展关系,能够经济有效地利用光能和地力,达到高产、稳产、优质、低消耗的目的。
Millet is one of the major cultivated crops in our province, but after seventies, due to a variety of reasons, sown area dropped significantly. In recent years, the sown area has been gradually restored and developed, the production conditions have been improved, and the production level has been continuously raised. How to determine the appropriate density of millet cultivation under higher fertilizer and water conditions in order to give full play to its yield potential and obtain higher yield is an important issue urgently needed to be solved in the current production. To this end, we conducted a three-year high-yield millet population structure test experimentally in Shenyang Agricultural College from 1981 to 1983. So as to understand and master the law of the development of group structure, study groups and individuals, aboveground and underground parts, vegetative organs and reproductive organs, develop sound and harmonious relations between the early and later stages, and be able to use light energy and earth power economically and efficiently to achieve high yields , Stable production, high quality, low consumption purposes.
