玉米是粮饲兼用的高产作物,是平原农区农牧结合的重要环节。近年来随着作物种植结构的调整,淮北玉米种植面积由1980年的161.5万亩发展到1986年的309.3万亩,并由过去的以春玉米为主改为以夏玉米为主。但该区玉米生产多沿用传统经验,尚未建立起一套科学的栽培技术体系,因而生产水平较低。为此,我们从系统理论出发,于1987年在濉溪县杨柳乡进行了淮北夏玉米高产栽培综合农艺措施的田间试验研究,建立了主要农艺措施的多维反应面数学模型,并对利用数学模型解析技术信息和进行生产决策作了初步探讨,为淮北地区夏玉米栽培提供了较为全面的科学依据。
Corn is a high-yield crop for both food and feed and is an important part of the integration of agriculture and animal husbandry in the plain farming areas. In recent years, with the adjustment of crop planting structure, the corn acreage in Huaibei has grown from 1.615 million mu in 1980 to 3.093 million mu in 1986, shifting from mainly maize to maize in the past. However, the corn production in this area often follows the traditional experience and has not yet established a set of scientific cultivation technology system, so the production level is relatively low. Therefore, based on the theory of system, we conducted a field experiment on the comprehensive agronomic measures for high-yield summer maize production in Huaibei County in 1987 in Yangliu Township, Suixi County. We established a multidimensional response surface mathematical model of the main agronomic practices and analyzed the use of mathematical models Technical information and decision-making made a preliminary study of production, Huaibei summer maize cultivation provides a more comprehensive scientific basis.
