河南省旱地小麦主要分布在洛阳、三门峡、郑州、平顶山、南阳、驻马店、新乡、安阳、鹤壁、济源等地,近年来河南省旱地小麦播种面积1 600多万亩,占全省麦播面积的20%以上。旱地小麦主要限制因素是干旱缺水,在正常年份旱地小麦产量可达300 kg以上。近年来,由于不断培肥地力、改进耕作制度,部分旱肥地小麦在降水较好的年份,小麦产量和水浇地小麦产量不相上下,亩产也能达到500 The dryland wheat in Henan Province is mainly distributed in Luoyang, Sanmenxia, ​​Zhengzhou, Pingdingshan, Nanyang, Zhumadian, Xinxiang, Anyang, Hebi, Jiyuan and other places. In recent years, the dry land area of ​​wheat in Henan Province has more than 16 million mu of sown area, More than 20%. The main limiting factor for dryland wheat is drought and water loss, with dryland wheat production up to 300 kg in normal years. In recent years, due to continuous fertilization of fertility, improve the farming system, some dry land wheat in better years of precipitation, wheat yield and irrigated land yield comparable, yield can reach 500
