摘要
根据欧氏距离的相似距离系数方法,利用温度、降水和日照资料,从年内热量、降水等几方面计算了修文县和贞丰花椒区的相似程度,确定相似等级,并通过对引种源地与目标地的花椒生态气候状况的对比分析,找出了修文花椒生态气候和品质比较优势以及存在的问题。结果表明:花椒在县境内海拔1 300 m以上地区虽可种植,但受冬末春初低温天气影响较大,产量不稳定;海拔在1 300 m以下地区为境内花椒稳产区。花椒产量和品质的形成受气候、土壤、栽培管理措施等诸多因素的影响。该研究结果可为修文农业结构调整和退耕还林扩大花椒种植面积提供气候依据。
According to the Euclidean distance similarity distance coefficient method,using temperature,precipitation and sunshine data,the similarity degree of pepper area in Xiuwen and Zhenfeng County was calculated from aspects of heat and precipitation etc.The comparative advantages and problems of pepper ecological climate and quality in Xiuwen were found through analysis on source region and target place.It was elicited that pepper can be grown in the county areas above 1 300 m sea level,but affected by the cold weather in late winter and early spring,the yield was instability.Pepper yield and quality was affected by the climate,soil,cultivation and management measures,and many other factors.The results could provide climate basis for adjusting agricultural structure and expanding pepper planting area in Xiuwen County.
