要合理的确定滴灌作物的灌溉制度,首先必须掌握滴灌作物的耗水量及其变化规律。本文根据滴灌特点和气象条件对作物耗水量的影响,对滴灌作物耗水量的计算进行了初步探讨,提出了耗水量与水面蒸发量的关系式及运算方法。根据该公式,只要知道某一地区的气象条件(如气温、湿度、风速、太阳辐射等),即可较为准确地估算某一滴灌作物的耗水量。文后有附表,供计算时直接查用。
To reasonably determine the drip irrigation system, we must first grasp the drip irrigation water consumption and its variation. According to the influence of drip irrigation characteristics and meteorological conditions on crop water consumption, the calculation of drip irrigation water consumption is preliminarily discussed, and the relationship between water consumption and water surface evaporation and the calculation method are proposed. According to the formula, the water consumption of a drip irrigation crop can be accurately estimated by knowing the meteorological conditions (such as temperature, humidity, wind speed, solar radiation, etc.) in a certain area. Text after the schedule for direct calculation of the calculation.
