Countermeasures to the influence of climate change on the apple production of Xianyang
摘要
Abstract
Based on the meteorological data from weather observation stations from establishing to 2009 in 12 counties of Xianyang, analysis was made of the characteristics of the change of meteorological factors from some aspects of temperature, precipitation, sunshine and relative humidity by the method of climate statistics. The results show that the climate .change has an obvious effect on apple production of Xianyang, and it is mainly represented by rising temperature,decreasing precipitation, sunshine time and relative humidity of the atmosphere. The climate warming exerts on advancing the time of the phenophases of apple trees; Green winter causes the overwintering base of spore germination and ova too high. It is very suitable for disease and pest growth; The drought is happening there with increasing frequency from decreasing precipitation; High temperature influences improvement of apple commodity rate; Low temperature and frost have seriously affected apple blooming, fruit setting and apple quality; Hail causes mechanical damages of flowering branch and a great quantity of apple drop; Rainy period in autumn influences coloring of fruit. Combined with the observation data of apple ecology since the 1980 s, evaluation is carry out of climate suitability to apple production, and countermeasure and suggestions are put forward for fighting against the climate change.关键词
