Sweet potato water cultivation seedling technology? How to cultivate sweet potato seedlings

Sweet potatoes should be disinfected before hydroponics, and after disinfection, an appropriate amount of water can be added to the container, if it is tap water, it needs to be exposed to the sun for 2 or 3 days before use. Place healthy sweet potatoes with sprouts in a glass container, taking care that the young shoots are exposed to the water. During the maintenance period, the water needs to be changed regularly, and fertilizer should be supplemented to promote the germination of sweet potatoes.

Sweet potatoes are common crop vegetables, which can be propagated by cuttings, soil culture, and hydroponic culture. The hydroponic method is relatively simple, easy to survive, and easy to manage. Before hydroponics, glass containers of appropriate size are used, disinfected with alcohol, and left to dry.

After drying, fill a glass container with nutrient-rich river or well water.

Pick a sturdy sweet potato with buds, wash it, and place it in a glass container for hydroponics, with the sprouted side facing up. Add 1 2 drops of nutrient solution dropwise in water in an appropriate amount.

Able to provide nutrients to sweet potatoes. Placing a glass container in a well-ventilated place indoors will stabilize the temperature between 5 and 35 degrees, which is conducive to sweet potato germination.

Hydroponic sweet potatoes, during the maintenance period, you need to change the water of the sweet potatoes regularly to keep the water clean. In spring and autumn, you generally need to change the water once every 3 or 4 days, and during the high temperature in summer, you generally need to change the water once every 2 3 days. During the water change, it should be noted that the water temperature should be consistent with the indoor temperature, if the water temperature is too high, it will affect the normal growth of sweet potatoes.

Sweet potatoes will sprout and grow leaves in the later stage, and during their growth, they can be appropriately applied with nitrogen fertilizer, which can promote the growth of branch buds and make the color of the leaves more green. After the growth of sweet potato seedlings is stable, they can be transplanted into loose, fertile, breathable and well-drained soil, or they can be cut for cuttings.

The specific operation is as follows:

1. Seedlings are sprouts that grow from the bud points of sweet potatoes, so you need to choose disease-free sweet potatoes first.

2. Sweet potato is a tropical crop, so it is suitable for planting in the southern region where the weather is hotter. If you want to grow your own, you can.

Sweet potato vines are cultivated in March and April. And wait.

In May and June, it is transplanted into the ground.

3. Put healthy sweet potatoes in the sink and wash them. And then everything in half. If the sweet potato is particularly large, cut it into three or four pieces.

4. Use an open bottle or cup and fill it with water, so that the sweet potato can be half immersed in water and half exposed to the water. The mouth of the bottle or cup should be large enough to fit the sweet potato, and the whole bottle should be filled with water.

5. Soak the sweet potatoes in water. Insert 4-5 toothpicks equidistant from the outside of the sweet potato, place the sweet potato incision facing down on the mouth of the bottle filled with water, and use the 4-5 toothpicks to hang the sweet potato at the mouth of the bottle, and submerge it in half of the water.

6. Give light and temperature. Move the bottle with the sweet potato to the windowsill where the sun shines.

7. Wait for 2-4 weeks for the top of the sweet potato to start growing young shoots with leaves.

8. After the sweet potatoes are covered with small seedlings, carefully pull them off one by one with your hands. They don't have roots yet, only small leaves.

9. Put some water in a bowl, about 3 cm or less, depending on the number of sweet potato seedlings. Place the sweet potato sprouts in a bowl and let their bases submerge in the water. After a few days, the roots grow from the bottom.

10. After 2-3 days, the sweet potato should grow roots. Drain the water from the bowl and take out the sweet potato seedlings and plant them.

Ten. 1. Sweet potatoes require a larger field than other horticultural vegetables. Each hole is 30-60 cm apart. The depth is 3 cm above the base of the plant to the base of the tuber.

12. Place the sweet potato seedlings one by one in the holes dug in advance and cover the stems with about centimeters of soil. The leaves of sweet potatoes will grow vines outward, while the roots will grow tubers at a depth of 15-30 cm in the soil.

Ten. 3. Cover the film. Protect sweet potatoes in cold weather by covering them with a film. This will also help stop weeds from growing and prevent sweet potato vines from overgrowing, robbing the tubers of nutrients.

Ten. Fourth, when sweet potatoes are just planted, they need a lot of water. Over time, they should be watered less until later only about once a week. Start watering daily, then reduce the number of waterings week by week.

Ten. 5. Sweet potatoes need a relatively long growth period, and they can not be harvested until early autumn. Continue to water and weed every week to allow the plants to grow healthily.

Ten. 6. About 120 days after planting, the sweet potatoes should have reached full maturity. If possible, postpone harvesting the sweet potatoes as much as possible (before frosting), as this will produce larger and tastier tubers.

First of all, let's take a look at the seedling time of sweet potatoes. Generally, sweet potato seeds should be cultivated in the spring between mid-February or mid-April, especially the sweet potatoes planted in spring must be in this period, especially in the area south of the Huai River is only after mid-February, which can be adjusted appropriately according to different regions, but the approximate time will not exceed April or so. Generally, there are many ways to add them to seedlings, but they are often used to warm or cold beds, covering them with a layer of film, this way to breed.

The second is that the open field arrangement is generally carried out before the middle of April, using direct open breeding, no need to cover the film, basically 45 days before the seedlings can be cultivated.

There are many ways to raise seedlings, and today I will introduce one method to you. The first method is the method of hibernation and cultivation of potato vines. In this method, the vines harvested in the autumn are kept until the following year and cultivated as sweet potato seedlings.

Their method is also relatively simple, first you have to keep their vines first. It is to choose some very robust vines without frost and disease after the sweet potato harvest in autumn, remove their leaves, keep one centimeter of petioles, and cut them in the same way as each section. The second point is to start forcing them to hibernate.

Place the cut vines in some specific solution, soak them for about two minutes, and then take them out to dry some moisture on the surface. With a specific solution, you can go directly to a specialty store and buy it. They are all more familiar, just buy some that sell better.

The third point is to prepare some ordinary sand first, and filter this ordinary sand through a sieve to remove some large particles and some impurities. Sprinkle some moisture on top and let it maintain a certain humidity. When the moisture is enough to make the sand loose and disperse after being pinched, this is basically enough.

The best time to cultivate sweet potato seedlings is in March and April every year, when cultivating sweet potato seedlings, you need to choose fresh and pest-free sweet potatoes, and then place the sweet potatoes in a shallow container filled with water, wait for about a week, the sweet potatoes will sprout, and then you can plant the sweet potato seedlings in fertile soil.

1. Cultivation time

When cultivating sweet potato seedlings, it is best to carry out them in March and April every spring, because the temperature at this time is about 15 degrees, and the light is relatively bright, which is conducive to the growth and germination of sweet potatoes, or to cultivate sweet potato seedlings in the greenhouse, the indoor temperature can be controlled between 15-20 degrees, so that the sweet potato seedlings grow vigorously.

2. Germination method

When cultivating sweet potato seedlings, you need to prepare a shallow basin that has been sterilized, then pour water into the shallow basin, and then place the sweet potato in water, and the depth of the shallow water cannot exceed the sweet potato, and finally you can move the sweet potato to a ventilated semi-shaded environment, wait for a few days, and the sweet potato will sprout.

3. Planting method

When planting sweet potato seedlings, you need to use a sharp knife to cut the sweet potatoes into small pieces, so that each sweet potato piece has 1-2 sprouts, and choose a sandy loam soil with good drainage, and then apply rotten farm fertilizer to it to make the soil more fertile, and then the sweet potato pieces can be planted into the soil.

4. Maintenance management

When maintaining sweet potatoes, it is necessary to apply urea to the plants about 15 days after planting, so that the growth rate of sweet potatoes is accelerated, and during the vigorous growth of sweet potatoes, it is necessary to prune the seedlings with more vigorous growth and more branches, and the side branches of the plants can be cut off to make the tubers of sweet potatoes get more nutrients.
