我国长江中下游属于南方多作大豆区,当地春大豆一般于4月上旬播种,7月下旬成熟,后茬接栽晚稻或晚秋旱作.近年来,这一地带的春大豆面积有所扩大,特别是双季稻地区,为了改善土壤结构,已腾出部份稻田改种春大豆.本项研究以合肥市为试点,拟探讨早、晚熟春大豆的发育时期,及其与主要气象因素的关系,为制订合理的栽培措施和选用适宜的品种提供若干依据.
The middle and lower reaches of the Yangtze River in the south belong to more soybean areas, the local spring soybeans are generally sowed in early April, mature in late July, the late crop in the late rice or late autumn autumn crop.In recent years, the area of spring soybean area has been expanded, Especially in the double cropping rice region, in order to improve the soil structure, some paddy field replanting spring soybeans have been released.This study took Hefei as a pilot to explore the developmental period of early and late spring spring soybean and its relationship with the main meteorological factors Relationship, in order to formulate reasonable cultivation measures and selection of suitable varieties provide some basis.
