目前,大豆平均产量水平远远低于大豆的产量潜力。如世界单产最高的意大利,亩产达到416斤,世界平均亩产只有188斤。我省高产公社平均亩产301斤,全省平均亩产为120斤左右。实际产量和产量潜力之间的这种差异,除了品种和其他栽培技术措施外,主要原因是某些营养条件没有达到最佳状态,在很大程度上是施肥不合理。为此,我们从1978年开始对大豆进行施肥技术的研究,以便迅速提高大豆单产。现将情况总结于后。
At present, the average yield of soybeans is far below the yield potential of soybeans. As the world’s highest yield of Italy, mu yield reached 416 pounds, the world average yield of only 188 pounds. High yield commune in our province average yield of 301 pounds, the province’s average yield of about 120 pounds per mu. The difference between the actual yield and the yield potential, apart from the variety and other cultivation techniques, is mainly due to the fact that some nutritional conditions have not reached the optimum status, which is to a large extent irrational to fertilization. To this end, we started in 1978 on soybean fertilization technology research, in order to rapidly increase soybean yield. Now the situation is summarized later.
