黑龙江省西部半干旱区向日葵水分生产函数试验研究

Study on sunflower water production function of semiarid area in the western of Heilongjiang

通过向日葵盆栽试验,依据向日葵不同水分处理条件下耗水量的试验资料求出了Jensen模型、Minhas模型、Stewart模型、Blank模型及Singh模型的参数,并通过对该5种模型拟和方程的拟和精度以及计算产量与实际产量相关性的对比分析,得出Jensen模型适宜于黑龙江省甘南县向日葵水分生产函数和此地区的向日葵水分生产函数模型。

In this paper, based on the pot-grown test of sunflower, the parameters of Jensen model, Minhas model, Stewart model, Blank model, Singh model were applied to analyze the sunflower water production function depended on consumed water quantity and the yield of the different irrigated. By means of comparative analysis of the fitting precision of upon models and the correlation of predicted yield with the function and actual yield, it showed that Jensen model was suited to sunflower water production function of Gannan county of Heilongjiang and the sunflower water production functions in the western semiarid area of Heilongjiang were established.
