太阳辐射及影响环境因子与核桃灌溉平衡分析

The Equilibrium Analysis for Solar Radiation,Effected Environmental Factor and Walnut Irrigation

为了探究太阳辐射、温度及相对湿度对于核桃灌溉需求的影响,确定最适宜核桃生长的灌溉量,设计了核桃灌溉平衡分析系统。结果表明:温度、相对湿度变化趋势滞于太阳辐射变化。同时,确定建立蒸腾作用模型参数,建立核桃蒸腾作用模型,进而建立蒸发蒸腾量和蒸腾量之间的关系,并采用经验公式,计算核桃耗水量。采用正交实验分析,以产量及出核率为指标,探究不同生长时期最优用水量及最重要时期。最后,综合产量及出核率分析结果,确定了核桃生长不同时期最优灌溉量。

Inorder to Exploring relationship between the solar radiation,temperature,relative humidity and walnut Irrigation,the equilibrium analysis system for walnut irrigation was achieved to find Optimum irrigation volume for walnut.Law of influence between environmental factor and solar radiation was that temperature and relative humidity lagged the solar radiation variety.The transpiration model for walnut was achieved after the parameters were defined.The model between evapotranspiration and transpiration was achieved,then the water consumption was calculated.Orthogonal experiment was used by the criterion of yield and ratio for nutlet.The optimum water consumption in different growth periods and the most important period was found.Optimum irrigation volume was found by comprehensive analysis between yield and ratio for nutlet.
