本研究采用二次通用旋转组合设计的方法,建立了以小麦产量和野燕麦防除率(％)为目标函数,考虑“燕麦枯”药剂施药量(公斤/公顷),喷液量(公斤/公顷)和施药时期(月/日)三个决策变量的数学模型。通过对模型的综合分析寻优提出:在麦田野燕麦危害严重地区(减产30％以上),“燕麦枯”施药量为8.25——10.05公斤/公顷,喷液量为450——675公斤/公顷,施药时期为12月/10日或翌年3月/10日前后的优化技术方案。运用此“燕麦枯”麦田施用技术,可获小麦每公顷产量4050公斤以上和野燕麦防除率75％以上。 In this study, a quadratic universal rotation combination design method was used to establish the objective function of wheat yield and wild oat control rate (%), taking into account the “oat dry” dose of pesticides (kg / ha) Ha) and the application period (month / day) three decision variables mathematical model. According to the comprehensive analysis of the model, it is proposed that in the field of serious damage of wild oat in wheat field (more than 30% reduction), the dosage of “oatmeal dry” is 8.25-10.05 kg / ha and the discharge volume is 450-675 kg / Hectare, application period for the December / 10 or March / 10 the following year, the optimal technical program. Use of this “oat dry” wheat field application technology, wheat yield of 4050 kg per hectare and wild oat control rate of 75% or more.
