温室青椒水分生产函数及灌溉制度研究

Study on Water Production Function and Irrigation System of Green Pepper in Solar Greenhouse

以青椒品种"35-619"为试材,通过温室内桶栽滴灌试验,基于2年试验数据,采用Jensen模型,通过多元线性回归方法获得青椒不同生育阶段水分敏感指数,确定了青椒的水分生产函数;进而利用遗传算法以相对产量最大为目标,利用C#.net编制优化程序对青椒的滴灌灌溉制度进行了优化。结果表明:温室秋冬茬滴灌青椒生育期内的灌溉水量为190mm,水分生产效率最高。

Taking green pepper variety of ＇35-619＇ as material,by drip irrigation experiment of Barrel-planted peppers in a greenhouse in both autumn and winter, the water sensitivity index and water production function of green pepper at different stages was obtained through multiple linear regression method based on 2-year test datum, adopting Jensen Model. Furtherly, compiling optimization program by C #. net language, drip irrigation regime of green pepper was optimized by using the genetic algorithm with the goal of maximizing the relative production. The results showed that drip irrigation water of green pepper dripping its whole growth period in a greenhouse in both autumn and winter was 190 mm with the highest water production efficiency.
