bamboo sponge (foam) hydroponics

Cultivating asparagus with sponge water has better air permeability than ordinary methods. On the one hand, the oxygen in the hydroponic bottle is more sufficient and there is no need to fill the hydroponic bottle with oxygen; On the other hand, sponge hydroponic asparagus has higher humidity and greener leaves, which is not easy to yellow leaves

1. Remove the potted asparagus from the soil, wash the roots, cut off the old roots, overgrown roots and diseased roots, and put them in a place with astigmatism and ventilation to dry

2. Prepare a hydroponic bottle and a sponge (flower and mud, foam), but put more holes on it. Cut the sponge so that the shape and size of the sponge can fit into the bottle mouth of the hydroponic bottle without dropping it. Note: the material of the sponge is preferably hard. p>

3. Draw a cross in the middle of the sponge so that the root system of asparagus can pass through the hole of the sponge, and then put it on the hydroponic flask. The root system of asparagus should not be submerged in water, but keep 1 / 3 in the air

4. The newly planted asparagus can be wrapped with a layer of black paper or plastic bag to avoid the light and make it root quickly

5. After a week or so, asparagus has new roots. You can put it in a place with astigmatism and ventilation. Don't bask in the sun< span>
