Production method:

1, prepare raw materials

Bean cake fertilizer can be bought at the local flower market, and the price is very cheap. Of course, if you grind soybean milk at home, you can also use soybean paste residue instead.

2, bean cake (residue) treatment

Grind the prepared bean cake (residue) into small particles. The smaller the particles, the shorter the fermentation time and the more complete the fermentation. If it is bean paste residue, this step can be omitted.

3. Select a container

Choose a small sealed fermentation container. The selection requirements of fermentation containers are low, as long as they can be sealed. Generally, you can choose the mineral water bottle you usually use, and the small one is easy to find.

4, adding water for fermentation

The ratio of ground bean dregs to water is 1: 10, which is put into a bottle, sealed and placed in a high temperature and dark place. Ten days in summer and fermentation can be completed in winter. Mix the upper fermentation broth with water 5: 1 for watering flowers. It is very common to raise chlorophytum.

Second, matters needing attention

1, sealed container fermentation, need to open air every 3-4 days to prevent bursting;

2, ferrous sulfate is added to the fermentation product to prevent oxidation, and orange peel can avoid unpleasant air temperature;

3. Remember not to water the flowers directly with bean dregs water, because unfermented bean dregs will release heat when fermented in the soil, which is easy to make flowers and burn roots;

4. The fermentation temperature should be controlled at about 15-20℃. If the temperature is too low, the fermentation will be slow.
