气候变暖对河南宜阳朝天椒种植的影响及对策

Effects of Warming Climate on Cultivation of Pod Pepper in Yiyang County of Henan Province and Its Countermeasures

通过对河南宜阳朝天椒大田生产的气候生态环境特征的分析,选取宜阳近50年的气温、降水、日照和相对湿度4个对朝天椒生产影响最大的气象因子,分析其变化特点,并对朝天椒所需适宜气候特征做了相似性分析,得出气候变暖和日照增加向有利于朝天椒种植的方向发展,但降雨量减少会影响朝天椒的生产,由此提出了采用温棚育苗、提早播种、加强田间管理以及做好人工增雨和蓄水等措施。

The climate characteristics of the ecological environment of pod pepper field production in Yiyang county of Henan province were studied,four meteorological factors（air temperature,precipitation,sunlight and relative humidity） which had great impact on pod pepper production in Yiyang county in recent 50 years were selected,and their changeable characters and the suitable climate conditions for pod pepper growth were analyzed.It was concluded that the warming climate and more sunlight benefited to the growth of pod pepper,but less precipitation could affect the production of pod pepper.Based on the above results,this paper put forward the following countermeasures： seedling-rearing in warm greenhouse,earlier sowing,good field management,and artificial precipitation and sluice.
