Influence of Climate Conditions on Potato Yield and Study on the Forecasting Model of Potato Yield

SUN Jun et al (Ningxia Key Laboratory for Meteorological Disaster Prevention and Reduction,Yinchuan,Ningxia 750002)  
[Objective]The aim was to research influence of climate conditions on potato yield and establish the forecasting model of potato yield. [Method]SPSS(Statistical Package for the Social Sciences) was used to separate potato output into meteorological yield and tendency yield over the years,and analysis of the relation between potato climate yield and meteoro-logical factors was carried out. [Result]The result showed that affecting yield factor consisted of the universality and regional. The universality included vapour pressure or relative humidity of air in last August-September,precipitation in late June to early July and in mid-August;The regional included precipitation in January and in earlyl to mid Aprial,vapour pressure of air in May. Prediction model about yield was established by using stepwise regression method ,that qualified rates of fitting better quality. [Conclusion]Because of its long effective period,high accuracy and simplicity to dalculate,the methd provided a guarantee for weather service on the crop farming of potatoes.
