Now everyone will stay healthy and choose to grow their own vegetables. Besides growing vegetables in the soil, they can also choose hydroponics. It's also a good idea to use beverage bottles. Let's look at the method of hydroponics vegetables with beverage bottles.
Method of hydroponics vegetables in beverage bottles 1 1 beverage bottle treatment
In the method of hydroponic vegetables with beverage bottles, it is necessary to make hydroponic containers first, which requires processing beverage bottles first. Choose a transparent beverage bottle, cut it in 2/3 places, leaving only the bottom beverage bottle, and then clean and disinfect the beverage bottle.
Step 2 choose seedlings
Choose healthy seedlings for hydroponic vegetables, and be careful not to choose seedlings with yellow leaves or poor growth. At the same time, comb the roots of vegetable seedlings, remove the residual roots, disinfect them and put them in the shade to dry the wounds.
3, foam cutting
Hydroponic vegetables do not directly put vegetables in water, and transplanted seedlings need to prepare foam. The size of the foam is equivalent to the diameter of the upper end of the previously cut beverage bottle, and then a small hole the size of a vegetable seedling is punched in the foam to facilitate the cutting of the seedling.
4. Prepare nutrient solution
Hydroponic vegetables can not be successfully cultivated and grow sturdily by relying solely on water, but also need to prepare nutrient solution that can provide sufficient nutrition for vegetables. Nutrient solution can generally be bought in the market, as long as it can provide nutrition.
5, hydroponic cultivation
After the preparation is completed, pour the nutrient solution into the bottle, then put the foam on the bottle mouth and cut the vegetable seedlings into holes. Pay attention to the height of nutrient solution to soak only the roots of vegetables, and then put the beverage bottle in a well-ventilated and bright place for maintenance.
6. Post maintenance
After hydroponics of vegetables, we should do a good job in the later stage of' maintenance'. First, the nutrient solution should be replaced once a week to make it have enough nutrition for growth. Let it receive enough sunlight scattering at ordinary times and water it every day to make it grow normally.
Hydroponics of vegetables in beverage bottles II. Hydroponics of water spinach.
1, select container
The hydroponics of water spinach depends on what kind of water you grow. If it is a pond, water tank or water basin hydroponics, it is necessary to make a floating bed, otherwise the whole water spinach will definitely rot due to lack of oxygen. If you are hydroponics with cups and bottles, you can omit the floating bed step, and just put the water spinach into the bottle after processing.
2. Planting method
Water spinach needs to be fixed on a special floating bed in large-scale hydroponics. The floating bed can simply insert and fix the stems of water spinach with plastic plates, or fix the stems of water spinach with wooden strips and bamboo strips crossing each other with ropes. In short, you can make good use of the tools around you, as long as you achieve the purpose of floating bed. In the case of small containers, there is no need to consider the problem of water spinach planting, just stand up and fix it a little.
3. Fertilization control
Fertilization is usually carried out within one week after hydroponic planting is fixed, and it can grow freely without too much management. Usually, you can apply some flower fertilizer or vegetable fertilizer, usually ten liters of water and one gram of urea and five liters of water and one gram of compound fertilizer. If you pick hydroponic water spinach, you can fertilize it. If you don't want to buy chemical fertilizer for fertilization, you can also use plant ash soaked liquid for topdressing, or use soil soaked liquid for topdressing. This method is also effective.
