| Abstract: | The principle protectively applied nitrogen to soybean wasbased on the experiments either adding urease inhibitor, the hydroquinone(HQ) in urea or regulating high ratio of C/N as the "nitrogen factoreffect" of the wheat-straw. The applied foreground of protectivelyapplied nitrogen to soybean was verified pritmarily under the differentconditions either in the sandy loam soil in the pots or in theAlbic soil in the fields. Thus, only though the full development ofsoybean symbiotic system of nitrogen fixation as well as the improvementof nitrogen provided in the soil, can we hope to coordinate the bothnitrogen resources to supply the soybean for grain protein. The yield ofsoybean was increased up 10-50% in the experiment than that in theordinary rules applied fertilizer nitrogen. |
