Winter greenhouse leaf surface fertilization 5 points

To fertilize greenhouse vegetables in winter, it is necessary to spray the vegetable leaves after diluting the micro-fertilizer, which is more economical and effective. However, during the spraying process, you must pay attention to the following five main points:

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 period of spraying the fertilizer must be determined according to different vegetable varieties and different varieties of fertilizers, and it is generally appropriate to spray when flowering.

The amount of general mu fertilizer solution 40 to 70 kg, can make the stems and leaves of vegetables wet.

The time is to reduce the loss of trace fertilizer during the spraying process, which is beneficial to the absorption of the leaves. Spraying should be performed in the 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, which will help improve the spraying. effect.
