洛阳地区处于豫西丘陵山区,全区有60%的麦田(约300万亩)是丘陵旱地.小麦生育期间降雨量约为250毫米左右,而年度之间变幅很大,且分布不均;加之水土流失严重和劳畜力不足,耕作粗放,早地小麦亩产长期徘徊在100-250斤之间.本地区水源缺乏,地下水位多在1OO米以下,发展水利相当困难.因此,小麦产量常决定于降雨量 Luoyang area is in the hilly and mountainous area in the west of Henan province, and 60% of the wheat field (about 300 mu) in the whole region is a hilly dry land. The rainfall during the wheat growing period is about 250 millimeters, but fluctuates widely and unevenly throughout the year. Coupled with the serious soil erosion and shortage of livestock and poultry, extensive farming, wheat yield per acre early in the hovering at 100-250 kg between the lack of water in the region, the groundwater table more than 1OO meters, the development of water is quite difficult.Therefore, the yield of wheat often Depends on the rainfall
