依据流体内平板热平衡理论 ,对葡萄园内的叶温、湿度、辐射、气温和风等环境气象因子进行小气候观测 ,并取得了葡萄园凝露时间的解释模拟经验公式和参数 ,为葡萄园的病虫害预报、防治决策提供了科学依据 Based on the theory of plate heat balance in fluid, microclimate observation was conducted on the environmental meteorological factors such as leaf temperature, humidity, radiation, temperature and wind in the vineyard. The experiential formulas and parameters of the condensation time of the vineyard were obtained, Forecast, prevention and control decision-making provides a scientific basis
