固原市马铃薯、西芹特色种植气象指标体系研究

Study on the Meteorological Index System for the Chara cteristic Plant-ing of Potato and Celery in Guyuan City

为研究固原市马铃薯、西芹气象指标体系,应用SPSS软件对西吉县马铃薯、西芹生长期生物量和气象条件进行相关分析,结果表明二者有密切的相关关系,生物学意义明确;通过建立关系模型,计算出马铃薯、西芹全生育期气象指标,数据可靠、可信。统计结果也表明,固原市4县1区气候变化规律极为相似,据此推算固原市马铃薯、西芹生育期资料,用一套指标辅助马铃薯、西芹生育期的方法表述固原市马铃薯、西芹生长期气象指标体系。

To study on meteorological index system for the characteristic plant- ing of potato and celery in Xiji County, SPSS was employed to analyze the correlation between biomass and meteoro- logical conditions in the growth season of potato and celery, the results showed that both of them were highly correlated and had definite biological significance. By establishing the relational model, meteorological indexes of potato and celery in the whole growth season were calculated, the data was reliable. The statistics also showed the meteorological change regularity of 4 counties and 1 district in Guyuan City was extremely similar, on the basis of which the growth season data of potato and celery could be obtained, and the meteorological index system for the growth season of potato and celery in Guyuan was expressed by a series of indexes.
