The method of water insertion and bottle cultivation is not to use glass bottles, but to raise them

I am engaged in plant work, from a professional point of view, with iron barrels and aluminum barrels and other utensils, no effect, on the contrary, it is more durable Plant growth needs water, fertilizer, heat and light, these five factors, specifically in the potting environment water, fertilizer heat and light, very well controlled, the growth of the root system is mainly related to the aeration situation, and the light has almost nothing to do Only often loosen the soil, keep the ventilation good, and make the root system not lack water and fertilizer, the plant will grow robustly

Special attention should be paid to the nitrogen fertilizer can not be too much, and the water can not be too much, otherwise, the growth is weak, prone to pests and diseases, should be combined with the application of organic fertilizer, and appropriate drying seedlings When the fertilizer is lacking, you can spray foliar treasure or potassium dihydrogen phosphate, the concentration should be small, 2ppm is less than two parts per million The effect is very good

If there are not too many flowers and plants, you can make a tool that is also very useful, find a used mineral water bottle, and use a pin to pierce a few small holes in the bottle cap, on the line. Generally, a bottle of 3 to 5 drops of leaf treasure is about 2ppm. Tap water has chlorine added to it, so it should be dried in the sun.

Yes, because you can't see light even if you cultivate it in potting soil.

Just note that rusting the bucket will increase the iron ions in the water body.

Yes, it will grow better in some ways.

Because roots grow better when they don't see light than when they see light.

But from an ornamental point of view, it may be in a transparent container, which may be more beautiful.

If it's a regular container like a cylinder, you pour it so that the water surface coincides with the diagonal. At this time, the water is halfway. Seek adoption.

The main thing is that the quality of the olive oil glass bottles and iron drums are the outer packaging that does not affect it.

It is best to choose glass bottles, which are easy to keep fresh. You can learn about olive world olive oil, imported from Spain, with good quality.

a。Concentrated sulfuric acid itself does not react with iron. However, the title says that it is cleaned with water, so the concentrated sulfuric acid remaining on the wall of the barrel becomes dilute sulfuric acid, and a reaction occurs. Hydrogen gas is produced with an open flame**, and several other utensils do not react regardless of the concentration of sulfuric acid.

Follow the order table of metal activity.

A Tietong and sulfuric acid are replaced to produce hydrogen, and the mixture with air meets an open flame**!!

Have a nice day.

a Iron and sulphuric acid to produce hydrogen,**.

Glass bottles can oxidize and corrode iron, while glass bottles can't oxidize with silica.

Iron will rust and corrode faster when it encounters water and air.

If you wash it, it's no problem, if you don't wash it...

c Iron drums. fe+cuso4=feso4+cu

It is also the principle of wet copper smelting. bar. Thank you.

Iron bucket, the strong metal activity will replace the weak one, the order of strength from large to small is K, Ca, Na, Mg, Al, Zn, Fe, Cu, Hg, Ag, Pt, Au, Sn, Pb

Iron and copper CuSO4 + Fe = FeSO4 + Cu, the displacement reaction occurs, it is not so simple.

c Copper ions are displaced.

c Iron bucket will have a displacement reaction.

Pick C; Fe will Cu2+ in CuSO4 solution to generate Cu; It can be found according to the order table of metal activity.

The answer is C because iron is more active than copper, and iron will be replaced from the copper sulfate solution.

The iron bucket does not work, and a displacement reaction occurs, generating divalent iron ions and copper.

Glass glue should be sold acidic, that is, quick-drying.

Once it's done, wipe off the excess with a rag.

502 can't be used, that guy can't manage it for a few days, and it will be sold in white glass glue hardware stores.

Remember, it's acidic.

The alkaline ones are very slow and take more than ten hours to dry.

I really want to think about 5 or 6 pieces!

It's big, it's a bit overkill.

Ha ha! After the AB glue is glued, it is difficult to wipe off the excess.

Therefore, glass glue is preferred.

Glass glue, shadowless glue.

1. Apply glass glue to the cross-section, and it will be firm for 24 hours after bonding.

2. Glass-to-glass bonding (793 structural adhesive) glass glue or use shadowless glue (fish tanks are basically shadowless glue, and ultraviolet lamps or sunlight must be used).

Some glass glue is soft, you must buy a hard one, or buy it directly for 3 seconds and 502, the two brothers will stick an ugly pimple.

Buy glass glue, or AB glue (good brothers), you can go to a hardware store or stationery store, or a large shopping mall supermarket to buy, it is best to bring your things, let people see, should not use this.

The small handle is plastic, and the brothers are fine, if it is a glass egg.

You can punch holes, but you have to use diamond drill bits, you go to glass processing factories all over the world, such as those shops in the glass door of the building materials market to see if they can help you achieve it, if you buy bottles in the factory, they will punch holes for you according to your requirements, and the general bottle factories have punching machines

Ordinary drill bits can't make glass holes; It can be easily processed with a diamond rotor; There is such a service to go to a glass processing shop.

No, you can't! Try some chemicals that react to glass.
