After making the soy milk, put the bean dregs into a plastic bottle, then add water until it is 80% full, then lightly twist the bottle cap and let it ferment in the sun, which usually takes about 1 month to complete. However, the smell of bean dregs after fermentation is really smelly. You can add a little orange peel to it during fermentation to slightly reduce the smell, and the orange peel can also be used as flower fertilizer after fermentation.

Note that bean dregs will produce some gas during fermentation. Loosen the bottle cap every week or so to avoid deforming the bottle. The bean dregs water after fermentation cannot be used directly. It must be mixed with at least 10 times more water before it can be used to water flowers.

Extended information:

Fertilizers are usually divided into two categories: organic fertilizers and inorganic fertilizers.

Organic fertilizer:

Mainly made of human excrement, livestock and poultry manure and various cakes, such as soybean cake, sesame paste residue, cottonseed cake, etc., which are rich in nitrogen, phosphorus and potassium. and trace elements. Nitrogen fertilizer can promote the luxuriance of flower branches and leaves; phosphorus fertilizer, mainly derived from bone meal, can promote bright flower colors and fruit enlargement; potassium fertilizer is a fertilizer mainly composed of plant ash, which can promote the robustness of flower branches and roots.

The application of organic fertilizer must be fermented. Raw fertilizer can easily damage the root system of flowers. Vermicompost refers to the feces excreted by earthworms. It is non-toxic, odorless, clean and hygienic. It contains 32.4 organic matter, 2.15 nitrogen, 1.76 phosphorus, 0.27 potassium, and 23 kinds of amino acids. It is a high-quality organic fertilizer for agriculture, forestry, flowers, and urban greening. .

Inorganic fertilizer:

It is easy to cause soil compaction. It is best to mix it with organic fertilizer for better effect. Inorganic fertilizers are divided into nitrogen fertilizers (such as urea, ammonium carbonate, ammonium bicarbonate, ammonia, ammonium chloride, calcium nitrate, etc.), phosphate fertilizers (such as superphosphate, calcium magnesium phosphorus, mostly used as base fertilizer additives, and the fertilizer effect is relatively slow; dihydrogen phosphate Potassium and ammonium phosphate are high-concentration quick-acting fertilizers that contain nitrogen and potassium and can be used as top dressing)

Potassium fertilizers (mainly potassium chloride, potassium sulfate, potassium dihydrogen phosphate, potassium nitrate, etc., are Quick-acting fertilizer, can be used as top dressing). Chemical fertilizers must be used in an appropriate amount, and the concentration should be controlled at 0.1-0.3. It should not be too concentrated, otherwise it will easily damage the flower roots and seedlings. Secondly, irrigation should be done immediately after applying chemical fertilizers.
