目前,农村中有机肥料的来源,尚不能满足农田施用的需要,因此,如何经济有效的施肥,以发挥现有农家肥的最大效果,提高单位面积的产量,是当前农业生产中急待解决的问题。 本试验是在1955年的试验基础上,继续进行的。目的是结合棉花各生长发育阶段的需要,如何正确施用有机与无机混合肥料,如何适当的增施氮肥,以提高它的最大肥效和扩大施肥面积,达到提高单位产量和改进品质的效果。
At present, the sources of organic fertilizers in rural areas can not meet the needs of farmland application. Therefore, how to use fertilizers economically and effectively to maximize the existing farm manure and increase yields per unit area is an urgent solution to the current agricultural production problem. This test is based on the experiment of 1955 and continues. The purpose is to combine the needs of each stage of cotton growth and development, how to properly use organic and inorganic compound fertilizers, and how to properly apply nitrogen fertilizer to increase its maximum efficiency and expand the area of fertilization to achieve the effect of improving unit yield and improving quality.
