大豆是一种节能、低耗、优质、高产的作物。由于栽培技术落后,成了低产作物。几年来的试验说明,大豆生产潜力很大。如何对大豆的传统栽培方法进行改革,把大豆生产提高到一个新的水平,是一个紧迫的课题。传统农业试验方法周期长,投资大,见效慢,而且很难摸清各栽培因子间的相互联系、相互制约的协调关系。因此,本试验采用了农业系统工程原理与方法对春大豆矮脚早进行田间试验,测定参数建立栽培因子空间多维反应面数学模型,利用微电脑处理信息,提供优化的综合农业方案,为生产决策提供科学依据。
Soybean is a kind of energy-saving, low-consumption, high-quality and high-yielding crop. Due to backward cultivation techniques, it has become a low-yield crop. Tests over the years show that soybean production has great potential. How to reform the traditional cultivation methods of soybean and raise the soybean production to a new level is an urgent issue. Traditional agricultural test methods have long cycle, big investment and slow response, and it is difficult to find out the interrelated and mutually constrained coordination relationship among cultivation factors. Therefore, this experiment adopted the principles and methods of agricultural systems engineering to conduct a field experiment of spring soybean aft foot early, and determined the parameters to establish mathematical model of space multidimensional reaction surface of cultivation factors. Using microcomputer processing information to provide optimized integrated agriculture program for production decision-making Scientific basis.
