Meteorological impact on the yield of Carya cathayensis
摘要
Abstract
[Objective]The study was to reveal the effect of meteorological factors on the yield of Carya cathayensis. [Method]The relation between the meteorological and yield data of three main Carya cathayensis producing areas in Lin＇an from 2008 to 2010 was analyzed. The impact of daily average temperature（DAT） ,total precipitation（TP） and days of precipitation（DOP） on the yield was also discussed by using mathematical modeling and statistic method. [Result]The results showed that the DAT at flower bud differentiation stage had great effect on yield and the correlation coefficient was 0.946, and TP and DOP had strong negative correlation with the yield during the flowering and pollination period and their correlation coefficients were -0.829, -0.796 respectively. The speculated critical DAT was 2.4 ℃, the critical TP was 162 mm and the critical DOP was 21 days. [Conclusion]The studies suggested that the extreme weather at flower bud differentiation stage and in the flowering period had certain effect on the yield of Carya cathaye nsis.关键词
