How to plant sweet potato seedlings

Planting density: high ridge double row planting, ploughing depth 25-30cm, ridge height 25-30cm, ridge width 100-120cm, ridge spacing 80cm, ridge surface cross planting double rows, row spacing 40-50cm, plant spacing 26-33cm. Transplanting time: when the air temperature is more than 15 ℃ and the shallow soil temperature reaches 17-18 ℃, it is suitable to transplant in cloudy days and the soil is not dry or wet. Transplanting method: the inverted insertion method can be used.

Prune sweet potato seedlings. The first choice is to prune the sweet potato seedlings first, that is, to prune some bad sweet potato seedlings, such as rotten roots, yellow leaves, and so on, to ensure the good integrity of sweet potato seedlings in order to grow better. Choose the planting site. After the sweet potato seedlings have been pruned, the planting site should be chosen. Because the vitality of sweet potato seedlings is relatively tenacious, the ability to adapt to the environment is also very strong.

Oblique insertion method: choose sweet potato seedlings with a length of 15cm to 20cm, plant seedlings into the soil about 10cm, leave seedlings on the ground 5cm 10cm, and the slope of sweet potato seedlings is about 45 degrees. The advantages are as follows: the cultivation method of transplanting seedlings is simple, the upper nodes of potato seedlings are more and larger, the drought resistance is good, the survival rate is high, and the tubers per plant are few and concentrated, which is suitable for mountainous areas and dry land with lack of water resources. The disadvantage is that there are few and small tubers in the lower nodes of sweet potato seedlings, and the size of tubers is not uniform.

The planting method of sweet potato seedlings by soil preparation and fertilization to plant sweet potato seedlings, it is best to choose the land with sufficient sunshine, deep soil, loose and fertile soil and convenient drainage and irrigation. after selecting the land, it is necessary to prepare the soil for soil preparation and deep turning of the soil. it is also necessary to apply an appropriate amount of base fertilizer to the soil to improve soil fertility, leveling and ridging, so that you can be ready for planting.

The method of burying leaves can be used in dry season. When burying soil, it is necessary to bury as many leaves as possible in the soil. The method of burying leaves has high survival rate and early seedling return, which is beneficial to increase production. Because of the large leaf area, sweet potato usually needs more water for its growth, especially after planting.

This method is often used in small area planting or summer potato planting. When planting, all the unroofed sweet potato seedlings are pressed in the soil, and the potato leaves are exposed to the surface. After planting, they are compacted with the soil and then watered. It can make the axillary buds of cuttings start early and sprout and branch.

How to grow sweet potatoes?

1. Soil preparation and fertilization: soil preparation should be carried out on a sunny day, and the soil should be broken and broken. After leveling, the fertilizer strip is applied at the bottom of the ridge, the distance between the ridge is 80 cm, and the ridge height is about 20 cm. Special organic compound fertilizer can be used for fertilizer. when the planting area is large, the soil n, p, k and organic matter should be determined, and the soil pH value should be determined in the south. The use of common compound fertilizer is not recommended.

2. When the sweet potato is planted by the method of accelerating germination, it is necessary to promote its germination. The fully mature and full seed potato can be selected and placed in an environment with a temperature of about 25-30 ℃ to promote its rapid germination. In addition, a sterilized sharp knife should be used to cut the seed potato into small pieces and ensure that there are 1-2 buds on each piece.

3. How to plant sweet potato (1) choose sandy loam or loam with loose and fertile soil and good performance of drainage and irrigation. (2) combined with ploughing, 2000kg rotten pig manure or compost was applied per mu, as well as 50kg superphosphate, 10kg potassium sulfate, leveling and opening the compartment with a width of about 33m.

Cultivation techniques of sweet potato seedlings how to cultivate sweet potato seedlings

Choose soil preparation to plant sweet potato seedlings, to choose flat, loose and fertile soil and convenient drainage and irrigation land to plant, before planting, first turn the land deeply, and mix an appropriate amount of fertilizer in the soil as the base fertilizer, this can make the soil more fertile, and then need to ridge, generally ridge distance of 60 cm, 40 cm high.

Pressure vine transplanting method: remove the top of the potato seedlings all pressed into the soil, leaves exposed to the ground, after planting covered with soil and watering. Due to the removal of the top, this method breaks the apical dominance, promotes the early initiation of axillary buds, node sprouting branches and rooting tubers, and has a wide range of stems and leaves, which is beneficial to the growth and growth of sweet potatoes. The disadvantage is that the drought resistance is poor, and it is time-consuming and laborious, so it is suitable for planting in small areas.

Oblique insertion method: choose sweet potato seedlings with a length of 15cm to 20cm, plant seedlings into the soil about 10cm, leave seedlings on the ground 5cm 10cm, and the slope of sweet potato seedlings is about 45 degrees. The advantages are as follows: the cultivation method of transplanting seedlings is simple, the upper nodes of potato seedlings are more and larger, the drought resistance is good, the survival rate is high, and the tubers per plant are few and concentrated, which is suitable for mountainous areas and dry land with lack of water resources. The disadvantage is that there are few and small tubers in the lower nodes of sweet potato seedlings, and the size of tubers is not uniform.

Planting time: sweet potato seedlings can be planted in spring, autumn and winter. Soil preparation and fertilization: choose loose and breathable sandy soil for deep ploughing and fertilization. Planting method: put the seedlings directly into the soil, keeping a distance of 50 centimeters between each tree. Growth environment: provide soft light for sweet potato and promote the growth of leaves.

The flat planting method is more suitable for small land area or family planting and so on. When planting, choose sweet potato seedlings of about 20 centimeters, and use shallow ditches to open ditches at the same time. To take out the sweet potato seedling tip to cover the soil, this planting method will greatly improve the survival rate, and is also conducive to the overall management of water and fertilizer. This method is often used in small area planting or summer potato planting.

How to cultivate sweet potato seedlings when cultivating sweet potato seedlings, we should choose healthy sweet potatoes that are fresh, free from damage, diseases and insect pests. Select fertile and loose sandy soil for cultivation. Plant the budding sweet potato in the soil and let it grow in the leeward and sunny place, watering it every two days. Wait until the sweet potato slowly grows new buds, and then cut the new buds off. Because the climatic conditions are different in different regions, the time of raising seedlings is also different.

How to cultivate sweet potato seedlings

1. The method of hibernating seedlings of potato vines. The method of hibernating potato vines is to save the potato vines harvested in autumn for sweet potato seedlings in the second year. Rattan cutting: after the harvest of sweet potatoes in autumn, choose strong sweet potato vines without frost and disease, remove leaves, retain 1 cm petiole, and cut every two sections. Forced dormancy: soak the cut potato vines in 0.5% Amfidrin solution for two minutes, remove and dry the surface moisture.

2. reasonable close planting and early planting at the right time. Lesser Fullness of Grain to the Summer Solstice is the best season for planting red pewter. To plant sweet potato seedlings on a sunny day, water them first and then plant them. The planting density can reach more than 3000 to 3500 plants per mu according to the ridge width and reasonable close planting. Then spraying the new high-fat film can effectively prevent the aboveground water from evaporating, the seedling water from transpirating, isolating the diseases and insect pests, quickly adapting to the new environment and growing healthily. Fertilizer and water management.

The planting methods of sweet potato seedlings include flat planting method, pressing vine method, oblique insertion method, direct insertion method, boat shape method and so on. The flat planting method is more suitable for small land area or family planting and so on. When planting, choose sweet potato seedlings of about 20 centimeters, and use shallow ditches to open ditches at the same time. To take out the sweet potato seedling tip to cover the soil, this planting method will greatly improve the survival rate, and is also conducive to the overall management of water and fertilizer.

Oblique insertion is a common planting method in modern times, which is more suitable for mountainous areas and dry land with lack of water resources. The advantages are that the upper nodes of potato seedlings are more and larger, the drought resistance is better, the survival rate is high, and the tuber per plant is less and concentrated. The disadvantage is that the lower nodes of sweet potato seedlings are less and small, and the size of sweet potato is not uniform, so it is more suitable for short seedling planting.
