我省传统的大豆种植方式,主要是旱地玉米或甘薯间套大豆及田埂栽培。50年代以来,由于玉米品种改良、种植密度增大,不宜间作大豆,加之过去片面强调“以粮为纲”,致使大豆面积锐减。1982年全省大豆面积仅有256万亩,几乎比1957年减少一半。目前全省大豆产量人平仅5斤左右,供求矛盾突出,平原区更甚。如广汉县年产大豆人平尚不足1斤。为了满足人民生活需要,促进养殖业和加工业的发展,建立合理的农业生态系统,平原区除大力发展田埂豆外,积
The province’s traditional soybean cultivation methods, mainly dryland corn or sweet potato intercropped soybean and field cultivation. Since the 1950s, due to the improvement of maize varieties, planting density increased, not intercropped with soybeans, combined with the previous one-sided emphasis on “food as the key link”, resulting in a sharp drop in soybean area. In 1982, the province’s soybean area was only 2.56 million mu, almost halved from 1957. At present, the output of soybean in the whole province is only about 5 kg, the contradiction between supply and demand is outstanding, and the plain area is even worse. Such as Guanghan County, with an annual output of less than 1 kg of soybeans. In order to meet the needs of the people’s life, promote the development of aquaculture and processing industries, and establish a reasonable agricultural ecosystem, in addition to vigorously developing the flat beans in the plain area,
