小麦是我省主栽作物之一,而且产量高,而积大。近几年来,由于连作增加,阔叶杂草危害日趋严重,致使产量大幅度下降。为此,我们于1984～1986年进行了防治麦田阔叶杂草数学模型的研究,旨在探索了投资少、产量高、收益大的施药除草技术,为经济合理用药提供科学依据。现总结如下: Wheat is one of the main crops in our province, and the yield is high, while the plot is big. In recent years, due to the continuous increase, broad-leaved weeds increasingly serious harm, resulting in a substantial decline in output. Therefore, in 1984 ~ 1986, we conducted a study on the mathematical model of controlling broadleaf weeds in wheat fields, and explored the application weeding technology with less investment, higher yield and larger yield, and provided a scientific basis for economical and rational drug use. Now summarized as follows:
