黄淮地区属温带、半干旱季风气候区,是我国花生主要产区之一。常年种植面积占全国花生总面积的30％左右。由于旱涝、盐碱,瘠薄等灾害性因素限制,花生荚果产量低而不稳,年平均亩产量只70—90公斤。近年来,由于生产条件的改善,小麦面积进一步扩大,与麦茬花生的季节劳力矛盾更为突出,为此扩大麦套花生,对缓解季节与劳力矛盾,提高复种指数 Huanghuai region is a temperate, semi-arid monsoon climate zone, is one of China’s major peanut producing areas. Annual perennial planting area accounts for about 30% of the total area of ​​peanut. Due to the drought, waterlogging, barren and other catastrophic factors, peanut pod production is low and unstable, the annual average yield per mu is only 70-90 kg. In recent years, due to the improvement of production conditions, the area of ​​wheat has been further expanded and the conflict with the seasonal labor of wheat stubble peanuts has become more prominent. To this end, the expansion of wheat peanuts has helped alleviate the contradiction between the season and labor and increase the multiple cropping index
