Variance Analysis of Climatic Potential Productivity of Tomato of Stagger Season in Guizhou Province
In order to understand the variance analysis of climatic potential productivity of tomato in different seasons,the research based on the 1961-2015 meteorological data of 81 weather stations,by the methods of step by step revisal,spatial interpolation and linear trend analysis,the temporal and spatial variation characteristics of YQ,YT,YW were analyzed.The results showed that during the study period,YQ,YT,YW showed a decreasing trend,while YT increased in winter-spring at a rate 174.11,226.52 kg/(hm2·10 a);The YQ,YT,YW of tomato in estivo-autumnal were in a decreasing trend,reduced by 355.24,317.99,427.67 kg/(hm2·10 a);The spacial distribution of YQ,YT,YW revealed that the YW of tomato in winter-spring decreased gradually from southeast to west,while the YW of tomato in estivo-autumnal decreased from southwest to northeast;The temperature and moisture content of YW tomato were revised,and the average yield of winter-spring,estivo-autumnal tomato decreased 35％ and 15％ respectively,and the rainfall was the main limiting factor for the YW of tomato.
