摘要
针对不同水分处理对棉花产量的影响,在大田生产条件下对棉花进行了非充分灌溉试验,以棉花大田试验数据为基础,采用最小二乘法拟合不同的水分生产函数模型,通过对比分析,建立了适合塔里木盆地棉花的水分生产函数模型,为棉花非充分灌溉条件下的灌溉制度优化提供了基础依据。
A field non sufficient irrigation experiment was carried out to investigate the effects of different water supplies on the cotton yield at different growth stages in cotton growing season under field production. Based on the experimental data, the water production functions of cotton are fitted with least square method. Compared the parameters of different models, we get the proper models of water production function for the cotton, which could provide reference for optimal irrigation schedule of the cotton.
