In recent years, with the development of fertilization, foliar fertilizer as strengthening crop nutrition and fertilization measures to prevent some kind of nutrient deficiency symptoms, and has been rapidly promoted and applied. Practice has proved that foliar fertilizer fertilizer is a fast, high utilization rate of fertilizer, one with a small amount of fertilization. Fast absorption: soil fertilization, the various nutrients are first adsorbed soil, some fertilizer must also go through a transformation process foliar fertilizer in the soil, and then exchange or diffusion of ions to be absorbed by plant roots, through the roots, stems dimension bundle, and then reach the leaves. Nutrient transport distance and slow. Foliar fertilization, various nutrients can be quickly absorbed by plant leaves directly into the plant from the leaves of crops involved in metabolism. Therefore, the role of its speed and effectiveness than soil fertilization to the quick. According to the research foliar type, blade root absorption of fat faster than fat absorption is faster around a fold. Foliar application of less effect quickly obvious foliar wholesale, improve the utilization of fertilizers. Is an economical, and good fertilization effect, especially some trace elements foliar application more unique. But we should also see the work of more trouble foliar fertilizer, labor cost more, while vulnerable to climatic conditions, but also because of different crop species and growth period, foliar fertilization effects are quite different. Therefore, we must root fertilization on the basis of the correct application of foliar fertilization technology in order to give full play foliar output, income effect.
