What are the cultivation methods and precautions of hydroponic sweet potato?

Culture time: no special requirements.

Culture containers: vases, cups, jars and other watertight things can be used.

Cultivation method: put a piece of sweet potato (bought in the market and planted by yourself, as long as it is sweet potato) into a container filled with water, and the water surface should not exceed the sweet potato, because the sweet potato will become lighter after budding and float on its own. Sweet potatoes germinate by their own nutrition, without adding any fertilizer, just water.

Anti-corrosion-most of them are exposed on the water, so don't throw them down, and pay attention to ventilation. Prepare a full and strong sweet potato, put it on a glass or transparent plastic container, and then fill the container with clear water. The water surface just touches the bottom of the sweet potato, but don't drown it too much to avoid rot.

2. Preventive measures

Choose those sweet potatoes that have sprouted and have no trauma; If both ends sprout, remember to choose the big end of the bud as the head and the small end of the root as the tail.

The container should be deep to give the roots enough room to grow;

It is beautiful to see white roots grow in a transparent container, but roots are more conducive to growth in a dark environment; The darker the better. It takes about 20 days to take root. As the roots grow bigger, the water level should be lowered appropriately. Let 1/3 of the root system emerge from the water. With the development of root system, leaves began to sprout and grow.

It should be placed in a sunny and hot place. If there is no sunshine, it must be placed in a room with high temperature, otherwise the leaves will grow slowly;

Don't change water every day, remember to replenish water. Generally, it can grow well in three or four months without special measures, but remember to replenish water when the water is running out.

When the shape is beautiful, put it in the right place as decoration, which is unique!

Other methods:

Hydroponic sweet potato can be cultivated with water;

The cultivation method is as follows:

1 first of all, we should raise seedlings. The method of raising seedlings is: using plastic greenhouses, we can raise seedlings in advance. The mixture of sawdust, shavings and nutrient soil was put into the seedling pot with the diameter of 1.5 cm, and the sweet potato seedlings were inserted upside down in the pot, and the normal water, fertilizer and temperature management were carried out to promote the big seedlings.

2, seedling tip, resulting in more vines, more trees, growing to more than 30 cm, remove the basin and some nutrient soil. The culture hole of the fixed cover of the culture tank is a U-shaped hole, which can be clamped into the culture hole from the side.

3, sweet potato seedlings from the nutrition pot to the soilless culture pot, the seedlings are not harmed, the sun, temperature, water and fertilizer are sufficient, and vines will soon grow and fill the cultivation space. Hydroponically cultivated sweet potato, stems and leaves occupy all the space, the sunlight is fully effective, multi-level utilization, no weeds, no human and animal interference, no shade, good ventilation, large temperature difference and sufficient CO2, which is beneficial to crop yield increase.

4. The harvest period of hydroponic sweet potato is not limited, and regular and quantitative standardized production can be formed according to the needs of processing and sales, saving manpower, material resources, site and loss of storage. In tropical areas, with high temperature all the year round, sweet potatoes can be planted for several years a year, with high yield and good quality, which can form a large-scale enterprise production base.

5. Hydroponic sweet potato can be planted on farms, buildings and warehouses without occupying cultivated land. It can be planted in desert, Gobi, water surface, balcony, courtyard, roof and other places with sunshine and water, with high and stable yield and balanced output. However, planting with soil, plowing and harrowing, and using chemical fertilizers have low yield and poor quality, and a large number of harvests are not convenient for processing.
