我们为了进一步提高大豆产量,从1973年开始试验亚硫酸氢钠(NaHSO_3)对大豆的增产效果。1973、1974两年进行了亚硫酸氢钠对大豆的适宜浓度和喷洒时期及其增产效能等试验。结果,“东农64—286”大豆品种在盛花期和盛荚期喷洒60ppm增产22%,100ppm增产15%。1974
In order to further increase soybean production, we started to test the effect of sodium bisulfite (NaHSO_3) on soybean yield increase in 1973. In 1973 and 1974, two experiments were carried out to determine the suitable concentration of sodium bisulfite for soybean and the spraying period and its yield increasing effect. As a result, 60% of Dongnong 64-286 soybean varieties were sprayed with 60ppm in full flowering and full-bloom stages, yielding 22% and 15% yield increase at 100ppm. 1974
