It is more economical and effective to fertilize greenhouse vegetables by diluting the trace fertilizer and spraying the leaves of the vegetables. However, during the spraying process, the following four points must be carefully grasped: The proper concentration and concentration can receive good results. If the application concentration is too high, it will not only be useless, but it will be harmful. In general, the appropriate spraying concentration of various fertilizers is: boric acid or borax solution 0.05% ~ 0.25%; ammonium molybdate solution 0.02% ~ 0.05%; zinc sulfate solution 0.05% ~ 0.2%; copper sulfate solution 0.01% ~ 0.02%; iron sulfate solution 0.2% to 1%. The amount of general fertilizer is 40 ~ 70 kg of mu, so that the stems and leaves wet the vegetables is appropriate. Frequent application of leaf fertilizer is less, so it is difficult to meet the needs of the entire growth and development process at a time. Therefore, it should generally be based on the length of the vegetable growth period, spraying 2 to 4 times is appropriate. The time is to reduce the losses of trace fertilizers during the spraying process, which is beneficial to the absorption of leaves. Spraying should be performed in cloudy or sunny afternoons from the afternoon to the evening. This can extend the residence time of the fertilizer solution on the leaves of the vegetables and improve the spraying effect. .
