目前,我县大豆生产水平较低。其原因主要是品种单一且退化严重,施肥水平较低,种植管理粗放。要发展大豆生产,推广应用综合增产技术十分必要。1989年,乐亭县农林局通过更新品种,推广综合增产技术,25600亩大豆高产田实现大幅度增产,平均亩产121.6公斤(间作自然亩),比对照田增产18.6公斤,增产率为18.06％。并带动全县41987亩大豆明显增产,平均亩产达到97公斤,比1988年提高12.8％。1990年,该县又有1万亩大豆高产田亩产达到150公斤,全县的34854亩
At present, my county soybean production is low. The main reason is the single species and serious degradation, low levels of fertilization, extensive plant management. To develop soybean production, promote the use of comprehensive production technology is necessary. In 1989, Laoting County Agriculture and Forestry Bureau through updating the variety, promotion of comprehensive production technology, 25600 acres of soybean yield increased significantly, the average yield 121.6 kg (intercrops of natural acres), 18.6 kg more yield than the control, the yield was 18.06% . And led the county 41987 acres of soybean production increased significantly, the average yield reached 97 kilograms, 12.8% higher than in 1988. In 1990, another 10,000 hectares of high-yield soybean in the county reached 150 kilograms per mu, and 34,854 mu
