多营养包膜尿素是一种以硫、镁、磷及各种微量元素为包膜层的缓效肥料，它不但使尿素适度缓效，而且包膜层也是植物营养，其中的微量元素不易被土壤固定。对玉米的农化试验表明，缓效多营养包膜尿素比等养分对照增产９．４％。从投入产出的经济效益看，以施多营养包膜尿素为最佳，投入产出比为２．４６。 Multi-nutrition coated urea is a slow-acting fertilizer with sulfur, magnesium, phosphorus and trace elements as its coating, which not only moderately slows the application of urea, but also encapsulates the plant nutrition, of which the trace elements are not easily Soil is fixed. The agrochemical experiments on corn showed that slow-release multi-nutrition coated urea increased yield by 9.4% over that of other nutrients. From the economic benefits of input and output, to take more nutrients coated urea as the best input-output ratio of 2.46.
