旱涝灾害是河南省发展粮食生产的主要制约因素。据1978～1988年统计资料,成灾面积与粮食总产有关,1983年成灾面积最小,粮食总产最高,1986年成灾面积最大,粮食总产最低。农田水利对粮食高产至关重要,改造中低产田更需要兴修农田水利。因此,建设旱涝保收田是河南省发展粮食生产的可靠保证。文中对河南省今后发展粮食生产提出了4点对策:即节水挖潜,扩大灌溉面积;增加投入,加快旱涝保收田建设步伐;山丘地区发展节水型灌溉,解决群众吃粮难的问题:强化管理,防止已有效益滑坡。
Droughts and floods are the main constraints on the development of food production in Henan Province. According to the statistical data from 1978 to 1988, the area affected by disaster was related to the total output of grain. In 1983, the area hardest hit by disaster was the lowest, with the highest total grain output, the largest disaster area in 1986 and the lowest total grain output. Farmland water conservancy is crucial to the high yield of grain. It is more necessary to rehabilitate farmland and water conservancy projects in middle and low yield fields. Therefore, the construction of drought, flood and paddy fields is a reliable guarantee for the development of grain production in Henan Province. In the article, four countermeasures are put forward for Henan Province to develop grain production in the future: saving water and tapping the potential, expanding irrigated area, increasing investment and speeding up the construction of paddy field, and developing water-saving irrigation in hills to solve the problem of food-poor people: strengthening management , To prevent the landslide has been effective.
