四月的太行山已经披上了一片新绿,前南峪的山岭翻滚着层层碧波,岗底村的苹果花开了,满树雪白,绿岭的核桃也长出了毛茸茸的幼果…几个月之后,辛勤劳作的人们又将收获满山的硕果。然而,太行山的守护神—河北农业大学教授李保国却永远离开了。三十五年来,李保国一头扎进太行山,无数在贫瘠山沟里『刨食』的农民因他而一甩『穷帽』。如今,荒山,一座座变绿;林果,一天天挂满枝头,可这位行走在太行山区的农民教授,却走了,巍巍太行黯然失色,山乡巨变的太行人民永远铭记…… April of the Taihang Mountains has been put on a new green, rolling the layers of the former South Valley of the mountain blue waves, apple trees in the village flowers, trees snow white, green walnut also grow hairy young fruit ... a few Months later, hard-working people will reap the fruits of the mountains. However, the patron saint of the Taihang Mountains, Li Baoguo, a professor at Hebei Agricultural University, has always left. Thirty-five years ago, Li Baoguo plunged into the Taihang Mountains. Countless peasants who dug their food in poor ravines were lurking in “poor hats” for him. Nowadays, the barren hills and green spaces are becoming green. The fruit of the tree is covered with branches every day. But this peasant professor who walked in the Taihang Mountains left. The towering Taihang is eclipsed.
