基于水量平衡方程的‘阳光玫瑰’葡萄精量灌溉决策管理

Decision Management on Precision Irrigation of‘Shine Muscat’Grape Based on Water Balance Equation

水分管理是葡萄栽培管理的重要组成部分。为实现‘阳光玫瑰’葡萄的精量灌溉,根据不同生育阶段的水分需求规律,构建基于水量平衡的精量灌溉决策模型;以主要根系吸水层(60 cm土层)为土壤湿润深度,将葡萄园土壤墒情监测系统得到的土壤含水量数据作为输入项,同时以气象因子为参数修正作物系数,结合天气预报数据决策未来时段内的具体需灌溉时间及灌溉量,以期为葡萄精量灌溉决策提供理论和实践参考。从实际生产需求出发,开发了‘阳光玫瑰’葡萄数字化管理平台,内嵌了大数据应用分析、环境监测、灌溉管理、专家知识库等功能,为用户实现适时适量灌溉管理提供了参考。

Water management is an important part of grape production.In order to realize precision irrigation,the study of precision irrigation decision-making model based on water balance was performed according to the water demand rules of different development stages;the water balance model was constructed based on the main root water absorption layer(60 cm soil layer)as the planned wetting depth of the soil;the soil water content data obtained by the soil moisture monitoring system of the vineyard was used as the input item.At the same time,the crop coefficient was modified based on the meteorological factors as the parameters,and combined with the weather forecast data,the specific irrigation time and irrigation amount in the future period were determined,which could provide support for the precision irrigation decision of’Shine Muscat’planting.Based on the actual production demand,’Shine Muscat’grape digital management platform was developed,with embedded functions such as big data application analysis,environmental monitoring,irrigation management and expert knowledge base,which provided a reference for users to realize timely and appropriate irrigation management.
