To apply micro-fertilizer to vegetables, we need to make a good "six off"

Concentration off concentration can receive good results. If the application concentration is too high, it will not only be useless but harmful. In general, the appropriate spraying concentration of various fertilizers is: boric acid or borax solution 0.05% ~ 0.2; 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% ~ 1%.

The dosage is 40-75 kilograms of a fertilizing liquid, which can make the stems and leaves of the vegetables wet.

Frequently, the amount of fertilizer used for leaf spraying is less, so it is difficult to meet the needs of all growth and development processes at one 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 cut to reduce the loss of micro fertilizer in the spraying process, which is conducive to the absorption of the leaves. Spraying should be performed in cloudy or sunny afternoons and evenings so as to prolong the residence time of the fertilizer solution on the leaves of the vegetables and improve the spray rate. Effect.

The time period for spraying and removing fertilizer must be determined according to different vegetable varieties and different types of micro-fertilizers, and it is generally appropriate to spray before flowering.

Mixed spray and mixed fertilizer spraying, or mixed with other fertilizers and pesticides, can save the process, play a "multi-effect" effect. However, it is necessary to pay attention to clarifying fertility and medicinal properties when mixing, and if they are of opposite nature, they will interfere with each other and must not be mixed. All kinds of trace fertilizers should not be mixed with alkaline fertilizers such as grass ash and lime; zinc fertilizers should not be mixed with superphosphate: copper fertilizers should not be mixed with potassium dihydrogen phosphate solution.
