通过对紧凑型、半紧凑型、平展型玉米的产量结构、群体结构发展规律、干物重变化、氮磷钾三素的累积和抗旱系数的研究，为三种玉米株型的合理密度提供依据；同时开展的栽培措施研究，为三种玉米株型制定出了相应的配套技术。
Through the research on the yield structure, the development of population structure, the change of dry matter weight, the accumulation of N, P and K and the drought resistance coefficient of compact, semi-compact and flat-typed maize, the reasonable density of three maize plant types was provided. At the same time to carry out cultivation measures research, for the three types of corn developed a corresponding supporting technology.
