摘要
用1991~1995年地膜棉花地理分期播种试验资料,建立了生长速度、产量和霜前花率模型,推算了各种农业气象指标,并用实况进行了验证。以模式和指标为依据,用宁夏各地1961~1990年气候资料和小网格订正资料模拟各地逐年生长进程、产量和霜前花率,统计其概率分布,分别绘出分布图,分析了宁夏各地发展地膜棉的适宜程度并做出了区划。
In this paper, statistical models for growing rate, yield and yield percentage prior to frost arrival were established and verified for film covered cotton crop based on the five year staging sowing experiment from 1991 to 1995. Concerned agrometeorological indices were also derived and examined against the real data. Taking climatic data and grid interpolated one in every place of Ningxia from 1961 to 1990 as inputs to the models, growing process of the cotton, yield and yield percentage prior to frost arrival were modelled and their probability distributions were computed and drawn. Finally, the preference degree of planting film covered cotton was analyzed and regionalized in the Ningxia.
