为了提高麦垄套种夏花生产量,同时又节水,于河南省新乡县古固寨镇开展了夏花生节水高产试验研究。研究结果表明,麦垄套夏花生高产栽培必须把小麦和花生两季作为一个整体进行综合考虑;既要考虑品种结构和种植模式的优化,又要根据这两种作物需肥需水规律进行合理水肥运筹。冬小麦应选用适当晚播、早熟的品种,如豫麦18-64系和温麦4号、6号等,采用宽行 24 cm、窄行 12 cm的宽窄耧播种;于麦收前 10~15 d在小麦宽垄内穴播增产潜力较大的海花1号、豫花7号等中熟品种花生。夏花生的关键节水灌溉期在萌发出苗期和盛花结荚期;高产夏花生必须施肥,根据豫北、豫东沙土地供肥特性与夏花生需肥规律,应重施磷肥、增施微肥、补施氮肥。
In order to improve the summer wheat yield interplanted with wheat and wheat, at the same time saving water, we carried out summer peanut water-saving and high-yield experiment in Guguzhai Town, Xinxiang County, Henan Province. The results showed that wheat and peanut must be considered as a whole in the high-yielding summer peanut cultivation of wheat and wheat. Considering the optimization of the variety structure and planting mode, it should also be reasonable according to the law of fertilization and water requirement of the two crops Water and fertilizer operations. Winter wheat should use appropriate late-sowing, precocious varieties, such as Yumai 18-64 and Wenmai 4, 6, etc., using broad-width 24 cm, narrow width 12 cm width sowing; wheat received 10-15 d In the wide ridge of wheat, it has the potential to increase the yield of peanuts, such as Haihua No.1 and Yuhua No.7, with medium maturity. The key water-saving irrigation period of summer peanut is in germination and seedling stage; the high-yield summer peanut must be fertilized. According to the characteristics of fertilization and the requirement of summer peanut in Yubei and Yudong areas, , Make up nitrogen fertilizer.
