温室滴灌西瓜作物系数的计算及模拟

Calculation and simulation of crop coefficients of watermelons by greenhouse drip irrigation

根据设施栽培蔬菜需水量试验资料,采用FAO-56推荐的单作物系数法计算了大棚西瓜的温室系数。以温室内气象因素为变量对西瓜作物温室系数进行了模拟。结果表明,作物温室系数与温室内气象因素表现出较好的线性与非线性多项式关系,F检验结果也表明两者之间表现出显著相关性。

Based on the experimental data of water requirement in installation cultivation of vegetables, the greenhouse coefficient of watermelons by greenhouse cultivation was calculated by single crop coefficient approach recommended by FAO-56. The simulation of the greenhouse coeflacient of watermelons with the meteorological parameter in greenhouse as rariable demonstrates that there are good linear- and nonlinear-multinomial relationships between the greenhouse coefficient of crops and the meteorological parameter in greenhouse. F test result shows that the two factors are of high correlation.
