摘要
Abstract
[Objective] The research aimed to study the influence of climatic variation on rife production in Anqing area. [Method] Based on the temperature and precipitation data in rice growth period (May-November) during 1980-2009, by using 5 - year moving average method, the moving average charts of temperature and rainfall were made. The variation characteristics of main factors (temperature and precipitation) which affected rice growth were analyzed. By using line moving average simulation method, |he climatic yield was separated, and the influence of climatic factor on rice yield in Anqing zone was analyzed. [Result] In recent 30 years, the temperature bad the ruing trend in the rice growth period in Anqing zone. Started from 1993, the rising was obvious. But the rainfall had the declining trend, and the rainfall was stable after 2000. These were the climatic background of that rice yield had the quick increasing after 2000. Seen from the separated result of trend yield and meteorological yield, the variation range of relative meteorological yield was big, and the biggest one reached 27. 5% in the yield re duction year. In retcent 30 years, there were four yield reduction years. The relationship between meteorological yield of rice and temperature was the positive correlation except in September. The excessive rainfall in the mature harvested period of rice had the unfavorable influence on rice yield. The drought was the main meteorological agricultural disaster which affected the rice yield in the zone. [ Conclusion] The research provided the theory basis for improving grain yield in Anqing zone.关键词
