甘肃省气候条件对马铃薯生产安全影响浅析

The Impact of Climate Changes on Potato Production Safety in Gansu Province

分析了气候条件对甘肃省马铃薯生产安全的影响,认为河西地区的降水条件对马铃薯产量的影响各生育阶段均为正效应,其他地区的降水条件对马铃薯产量影响最大的时期为块茎增长期,其中块茎快速增长期为正效应,增长后期呈现负效应;马铃薯出苗至分枝前后,各地的热量条件对产量的影响均不敏感,但块茎增长期的高温则对产量的影响较大。

This paper analyses the climatic conditions of Gansu province potato production safety in the event of Hexi areas that the precipitation conditions on the yield of potatoes during the biological effects are positive, and precipitation conditions of other areas on the potato yield the greatest impact for a period of the tuber increase period, the period of tuber increase quickly is a positive effect, and the late is negative effects. Potato branch to emerge before and after the heat throughout the production conditions are not sensitive to the impact, but tuber increase of the temperature on yield is larger.
