Qualified and qualified fertilizers in production are selected according to the combination of organic and inorganic fertilizers, combination of basal fertilizers and top dressings, major elements, and reasonable supplements of trace elements, according to the characteristics of the crops at different growth stages, fertilizer characteristics, and soil nutrients. Status and target production, scientific application of trace element fertilizers in order to achieve high yield and quality. Pay attention to the concentration of fertilizer applied to the concentration can receive good results, high concentration is not only not beneficial but harmful. Usually the concentration is a few hundredths of a few, such as boric acid or borax 0.05% to 0.25%, ammonium molybdate 0.02% to 0.05%, copper sulfate 0.01% to 0.02%. If you need to increase the concentration, do not exceed 20% of the conventional concentration. Pay attention to the time to reduce the loss of trace fertilizer in the spraying process, the best choice for cloudy spraying, sunny days should be sprayed in the evening, in order to extend the moisturizing time of the fertilizer solution on the crop stems and leaves, in order to facilitate crop absorption. Note that the amount of trace elements needed for the crop is small, and the critical range of various trace elements from the lack to the excess is very narrow, and a slight lack or excess may cause harm. Generally, 40-75 kg of fertilizing liquid per acre is sprayed, which can evenly wet the stems and leaves of crops and avoid repeated application. The number of attention depends on the growth and development of the crop, usually 2 to 4 times. Proper mixing and spraying of micro-fertilizer, or mixed spraying with other fertilizers, can play a role of “one injection and multiple effectsâ€, but it is necessary to clarify the physical and chemical properties of fertilizers and pesticides to prevent chemical reactions and thus reduce fertilizer efficiency.
