随着大量农村劳动力转移、劳动力成本上升,如何保证种粮效益,减少用工,降低生产成本已成为不容忽视的“三农”问题。推广新型肥料,改变施肥方式是摆在农业专家和肥料企业面前的一个新课题。为进一步比较当前几种不同工艺生产的玉米缓释肥的肥效,为玉米缓释肥推广提供科学依据,在省农技站的技术指导下,特安排本试验。我
With the transfer of a large number of rural labors, the labor cost has risen. How to ensure the efficiency of grain growing, reduce the labor cost and reduce the production cost has become a problem that can not be ignored. To promote new fertilizers and change fertilization modes is a new task for agricultural experts and fertilizer companies. In order to further compare the fertilizer efficiency of the corn slow-release fertilizer produced by several different technologies and provide a scientific basis for the promotion of the corn slow-release fertilizer, under the technical guidance of the provincial agricultural technology station, the experiment was specially arranged.
