"旱、寒、薄、病"是商洛山区小麦生产的四大逆境胁迫因子,该区选用小麦品种的总体策略应以"抗逆型"品种为主,开展抗逆育种是最经济有效的途径。河谷川道、浅山丘陵、中高山区是商洛的三种最基本生态类型区,选用小麦品种的区域策略则应依据品种的不同特性实行三大区域合理布局,并实现良种良法综合配套,才能最大限度发挥优良品种的增产潜力。

Drought, cold, infertility and diseases' are four most adverse stressing factors in wheat production in Shangluo mountainous area. So strategically the wheat species selected there should be mainly 'adversityresistant' types.

The river valleys, hilly land and middle and large mountains are the typical ecoregions in Shangluo. So strategically the properties of the wheat varieties selected for Shangluo should comply with the different ecoregions and improved varieties should be correspondingly cultivated with proper measures in order to realize the maximal production potential. 
