一、研究的目的意义: 豫西丘陵旱作生态类型麦区,是全省十大生态类型麦区之一,常年种植小麦的面积,占全省的10％左右。由于本区干旱缺水、土壤瘠薄、栽培管理粗放,小麦产量低而不稳,亩产只有100公斤左右,常拉全省小麦产量的后腿。但是,不论哪个年份,都出现有亩产200公斤以上的地块,这说明本区存在着由低产变中产的生产潜力,只要栽培管理措施得当,是可以大幅度增产的。根据科学研究要走在生产前面,科学技术必须为经济建设服务的方针,为了提
First, the purpose of the study Significance: West Henan hills dry ecological type of wheat area, is one of the province’s top ten ecological type wheat area, perennial planting area of wheat, accounting for about 10% of the province. Due to the drought and water shortage in this area, the soil is infertile, the cultivation and management are extensive, the yield of wheat is low and unstable, and the yield per mu is only about 100 kg, which often hinds the hurdles of wheat production in the whole province. However, irrespective of the year, plots with a yield of more than 200 kg per mu have occurred. This shows that there is a potential for production in this area from low-yielding mutatis mutandis, and as long as proper cultivation and management measures are taken, production can be substantially increased. According to the scientific research to go before production, science and technology must serve the economic construction policy, in order to mention
