基于气象因素对豫西南春花生高产栽培安全性分析

对2001～2016年邓州市春花生全生育期及不同生育阶段平均气温、降雨、光照等气象因素变化进行分析,并探讨了气象因素变化对春花生生长发育的影响.结果表明,在春花生生育期内,自2001年至今,平均气温则呈递增趋势,但递增趋势较缓;降雨量呈递减趋势(播种期、花针期呈递增趋势),光照量呈逐年递减趋势(不同生育时期递减趋势不同),但光照量递减趋势强于降雨量.基于气象分析,结合春花生生长规律,科学选择品种和规划适宜播种模式,合理运筹肥水,在安全稳产的基础上实现持续高产.

Analysis of Security of High-yield Cultivation of Spring Peanut in the Southwest of Henan Province Based on Meteorological Factors

The changes of meteorological factors such as average temperature,precipitation and sunshine duration in the whole growth period and at various growth stages of spring peanut in Dengzhou City during 2001-2016 were analyzed,and their effects on the growth and development of spring peanut were discussed.The results show that from 2001 to 2016,average temperature tended to increase in the growth period of spring peanut in Dengzhou City,but the increasing trend was slow;precipitation showed a decreasing trend on the whole (it increased at the sowing and flowering stage);sunshine duration reduced year by year (the decreasing trend was different at various growth stages),but the decrease of sunshine duration was more obvious than that of precipitation.Based on the analysis of meteorological conditions and the growth rules of spring peanut,it is needed to scientifically choose varieties of spring peanut,plan suitable sowing patterns,apply and managefertilizer and water to reasonably realize sustainable high-yield of spring peanut based on its safe stable yield.
