摘要
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。
The experiment and study of water-saving and high yield of the summer peanut has been developed in the Guguzhai Township of Xinxiang County of Henan Province for the purpose of increasing yield of the summer peanut of planting on the ridge of wheatfield and saving water. The study shows that the wheat and summer peanut of two seasons crops should be considered as a whole process for high yield planting of the summer peanut of planting on the ridge of wheat field. The optimization of crops vari- ety structure and planting pattern should be taken into account and the reasonable water and fertilizer regulation should be also tak- en based on the law of water and fertilizer requirements of the two crops. The winter wheat must select the later sowing and early maturating variety, such as Yu wheat 18-64 series and Wen wheat 4, 6 and the wide row will be 24 cm and the narrow row 12 cm. The medium maturating variety peanut of Hai peanut 1 and Yu peanut 7 with higher yield potential should be hole sowed in 10 ~15 days before winter wheat harvest. The critical irrigation stages of the summer peanut are seedling and flowing. The high yield summer peanut should be fertilized with phosphate and nitrogen etc.
