Vegetable spraying micro-fertilizer should take six levels

First, the concentration is close to the concentration to receive good results, the application concentration is too high, not only useless, but harmful. Generally speaking, the suitable spraying concentration of various micro-fertilizers is: boric acid or borax solution 0.05-0.25; ammonium molybdate solution 0.02%-0.05%. The zinc sulfate solution is 0.05 to 0.2%; the copper sulfate solution is 0.01 to 0.02%; and the sulfuric acid to iron solution is 0.2 to 1%.
Second, the period of closure The application of micro-fertilizer must be based on different vegetable varieties and different micro-fertilizer varieties, generally sprayed before flowering is appropriate.
Third, the amount of application The amount of micro-fertilizer spray should vary according to the growth conditions. Generally, 40 to 75 kg of fertilization solution can make the stems and leaves of vegetables wet.
Fourth, the number of times Foliar spray generally uses less fertilizer, so it is difficult to meet the needs of all growth and development processes. Therefore, it is generally appropriate to spray 2 to 4 times according to the length of the vegetable growth period.
5. Time is set to reduce the loss of micro-fertilizer during the spraying process, which is beneficial to the absorption of the leaves. It should be sprayed from the afternoon or to the evening when it is cloudy or sunny, so that the residence time of the fertilizer solution on the vegetable leaves can be long. It is beneficial to improve the spraying effect.
Sixth, mixed spray off Mixing micro-fertilizer spray, or mixed with other fertilizers and pesticides, can save the process, play a "one spray multi-effect" role. However, when mixing, pay attention to clearing the fatness and medicinal properties. If the properties are opposite, they are mutually obstructive and must not be mixed. All kinds of micro-fertilizers should not be mixed with alkaline fertilizers such as grass ash and lime; zinc fertilizer should not be mixed with superphosphate; copper fertilizer should not be mixed with potassium dihydrogen phosphate solution. When mixing with pesticides, the dual effects of fertilizer efficiency and efficacy should be considered. For the sake of prudence, a small amount of solution of micro-fertilizer and pesticide should be placed in the same container before mixing. If there is no turbidity, precipitation and bubbles, it means that it can be mixed; if any of the above phenomena occurs, it indicates The two cannot be mixed. Generally speaking, all kinds of micro-fertilizers cannot be mixed with alkaline pesticides. When preparing a mixed spraying solution, generally, a micro-fertilizer is first formulated into an aqueous solution, and then other medicines and fertilizers are directly added to the prepared micro-fertilizer solution for dissolution.
