An Experimental Study of the Infuence of Moisture Fertilizer Effect on Soybean Yields
This is a study on the influence of different waterfertilizer coupling effect on soybean yields through a tub-planting experiment, the relation of irrigation-fertilization and soybean yields being analyzed, and an optimum water-fertilizer management model for soybean growing being put forward. The result shows that under the condition of this experiment, water effect is greater than the effect of nitrogenous fertilizer; in terms of single factor effect, with the increase of nitrogenous fertilizer or soil moisture, the yield shows a tendency of quadratic parabola, rising first, declining later; in terms of double-factor effect, a clear positive correlation between yields and water and nitrogen factors is showed with nitrogenous fertilizer and soil moisture within certain range: maximum yields come with the high-water and high-nitrogen condition; the ideal effect of the water-fertilizer function model provides a theoretical support for the stable high yield of soybean.
