特早熟玉米裸地种植正交试验研究初探

Preliminary Study on Orthogonal Experiment of Naked Corn Planting in Early Maturing Maize

采用正交试验法对晋西北五寨县推广的并单6号、龙源3号、德美亚1号3个玉米品种在旱裸地种植条件下的施肥、种植密度开展试验研究。试验得出,在晋西北生态条件下,特早熟玉米裸地种植在采用不同施肥水平、不同品种和种植密度的因素中,影响产量的主要因素首先是肥料,其次是品种,再次是密度。

The fertilization and planting density of three maize varieties, such as Bingdan No.6, Longyuan No.3 and Demeiya No.1 in northweste Shanxi Wuzhai county were carried out under dry bare land by orthogonal test. Through the experiments,among these factors,such as levels of different fertilizer, different varieties and different planting densities, drew the conclusion that the main factor of planning of the early maturity maize on bare land under northwest Shanxi ecological conditions is fertilizer, the next is variety than followed by density.
