Generally speaking, the suitable spraying concentration of various trace fertilizers is: boric acid or borax solution 0.05%-0.25%; ammonium molybdate solution

Fertilizer concentration: in the fertilizer spraying process, the fertilizer concentration should be appropriate in order to get a good effect, the application concentration is too high, not only useless, but harmful. Generally speaking, the suitable spraying concentrations of various trace fertilizers are: boric acid or borax solution 0.05%-0.25%, ammonium molybdate solution 0.02%-0.2%, zinc sulfate solution 0.05%-0.2%, copper sulfate solution 0.01%-0.2%, ferric sulfate solution 0.2%-0.1%, and the fertilizer solution concentration is too low to achieve the desired effect.

Fertilizer spraying period: the period of spraying micro-fertilizer must be determined according to different vegetable varieties and different varieties of micro-fertilizer, and it is generally appropriate to spray when it is in bloom.

Usage: generally 40-70 kg fertilizer solution per mu, in order to wet the stems and leaves of vegetables.

Fertilizer spraying times: leaf spraying generally uses less fertilizer, so it is difficult to meet all the growth needs at one time, so it is necessary to appropriately increase the number of fertilization to make up for the lack of fertilizer application.
