How to Planting Sweet Potato without Soil
In the impression of many people, besides sunlight and water, the growth of crops cannot loss land. However, with the continuous development of agricultural technology, people have created soilless cultivation, so that many crops can still grow after leaving the soil, and even grow better than in the soil, such as the soilless cultivation of sweet potatoes. Using this technology, sweet potatoes can grow in the air and are larger than those grown in the soil. Let me introduce to you the soilless cultivation technology of sweet potato.
1.Pruning
In the process of sweet potato seedlings growing into trees, pruning is the key. After transplanted for half a month, new branches will grow. At this time, it is necessary to start hanging vines. You can use ropes to hang the newly grown branches on the net frame, leave three to four branches at a distance of about one meter from the main trunk, and leave some branches at a position more than one meter away from the trunk, so that the branches too dense and thin are removed. During the growth of sweet potatoes, the branches can be pruned every five days in summer and every ten days in winter.
2. Additional Fertilization
After hanging vines, in order to enhance the plant's disease resistance and promote the growth of the roots, it is necessary to supplement trace elements. Spray the nutrient solution evenly on the whole plant, and spray it every half a month.
3.Flowering Management
Flowering of sweet potatoes is not a good thing as it competes for nutrients. Under normal circumstances, it is necessary to artificially destroy the flowers to reduce the waste of nutrients. Sweet potatoes will only bloom when the light is shortened, so we can suppress flowering by supplementing the light. Even in summer, when there are even cloudy days, it is necessary to increase the light for about 4 hours a day.
4.Fruiting period Management
Different from conventional sweet potato cultivation techniques, in soilless cultivation, growers carry out aerial pressure vines one month after transplanting sweet potato trees. First, put the planting media into the hanging pot. Then choose a strong vine, pull the vine down about ten centimeters, remove the leaves, hang the hanging pot on the grid, bury the vine in the media for about two or three centimeters, and then water it thoroughly. After that, water once every other week to meet the growth of sweet potatoes.
5.Pest Control
Sweet potato itself is relatively disease-resistant, and generally no disease will occur. When pests occur, biological control is generally used.
6.Picking
The sweet potatoes can be picked after hanging for about a month. Picking required two people to cooperate. Use scissors to cut upwards along the bottom of the pot. Cut off the roots in turn, remove all the fibrous roots, and finally put the potato vines back on the grid to continue growing.
Today, we want to introduce you to a new generation of planting media ---- Tenlead Plant Growing Cube. Tenlead Plant Growing Cube is made from phenolic foam. It provides a high quality,sterile and inert root growing environment. Hydroponic growing cube provides from 90%-98% air space in between its fibers while still giving excellent support for the plant. It is sterile and inorganic. Because it does not contain any organic matter, it helps to protect sweet potato’s roots from harmful microorganisms.
What most important is that it is biodegradable and will completely biodegrade after a period of time without polluting the environment. Conversely, some products that cannot be decomposed, such as rock wool, will take you a lot of time and cost to handle after planting. We firmly believe that it will be more valuable and expand its market in the future nursery garden work.
The planting cubes do not contain any chemicals, allowing sweet potato to grow healthier. Unlike soil, Our cubes do not block any nutrients. All elements in the nutrient solution can be used in plants, i.e. there is no soil interference. It is also effective in eliminating fungi and diseases common to young plants./It can also effectively eliminate the common fungi and diseases of young plants.
The above is the soilless cultivation technology of sweet potato. The sweet potato grows in the air, which avoids the disadvantage of harvesting together with the seedlings when harvesting. As long as the potato seedlings are kept, the purpose of continuous harvesting and high-quality and high-yield can be achieved.
