Sweet potato cultivation techniques

Seedlings

Early varieties should be cultivated with greenhouse + small arch shed + plastic film three-layer thermal insulation, and the mulch film should be used to cover the cultivation after early emergence, and the market should be advanced earlyConventional cultivation can use small arch shed + plastic film two-layer insulation seedlings. The seedbed is about a meter wide and 15 to 20 cm deep, and the bottom of the bed is covered with a layer of organic fertilizer and then watered and covered with soil.

The selection of seed potatoes requires typical characteristics of this variety, free of diseases and pests, and 100 to 250 grams of potato pieces. The density of the seed is about 3 cm apart, and the seed potatoes are covered with soil after they are arranged, with a thickness of 2 to 3 cm and not more than 5 cm, so as not to affect the emergence of seedlings. When 60% of the potato pieces have sprouted, remove the mulch.

When the temperature is above 20 on a sunny day, open the arch film and the greenhouse film at both ends for ventilation to prevent high temperature burning seedlings, keep the bed temperature 25 to 30, and the humidity is subject to the dry and wet of the bed soil. When the seedlings are 20 to 25 cm long and have 6 to 8 complete leaves, they can be cut and planted in the field.

Planting

When the average temperature is above 15, the seedlings can be cut and planted in the field, and due to the low temperature in the early stage (late April to mid-May), plastic film can be used for cultivation. When planting, the 4 nodes are inserted horizontally or obliquely into the soil, and the two leaves are exposed to the ground when the drought occurs, and the rest of the leaves are buried in the soil, so as to facilitate the survival of potato seedlings and the dispersion of potatoes evenly, improve the commodity rate and yield, and the planting density is 4000 acres, and the plant spacing is 20 cm.

Stewardship

Land preparation and fertilization: Land preparation should be carried out on a sunny day, and the soil should be broken and fine. After leveling, the fertilizer strip is applied to the bottom of the ridge, the ridge spacing is 80 cm, and the ridge height is about 20 cm.

Fertilizer can use special organic compound fertilizer, when the planting area is large, it is required to measure soil N, P, K and organic matter, and the soil pH value should be measured in the south. The use of ordinary compound fertilizers is not recommended.

Pruning and topping: For potato fields with more branches and more vigorous growth, two or three branches can be cut off, so that nutrients can flow back and the potato pieces can get more nutrients. Topping regulates the movement of nutrients and promotes the delivery of nutrients to the roots.

Remove the tips when the seedlings are 40 to 60 cm long, and when the branches are too vigorous.

Timely topdressing: about 15 days after transplanting, the seedling fertilizer is combined with the first tillage, and 750 to 1000kg of thin stool water or urea per mu is topdressed. Potato fertilizer is topdressing in the branching tuber stage, which is generally carried out within one month after transplanting in combination with the second tillage, mainly nitrogen fertilizer, combined with phosphorus and potassium fertilizer.

After the stem and leaves are sealed, the growth rate of the root tuber is faster, and the top dressing is applied when cracks appear in the ground. 10kg of topsac superphosphate leaching solution and 3kg of potassium sulfate per mu are mixed with 150 to 200kg of water to form a nutrient solution, which is watered along the seam in the afternoon on a cloudy or sunny day, and the top dressing is required to be uniform.

Sweet potatoes belong to the family of herbaceae. Our usual sweet potatoes grow underground, and when they are almost ripe, we dig them out of the ground with a shovel and rinse them for consumption. Sweet potatoes belong to the order Tubular Flowers, Spiraceae, annual herbaceous plants, more than 2 meters long, lying flat on the ground obliquely, the leaves are usually broadly ovate, 4-13 cm long and 3-13 cm wide, the corolla is pink, white, lilac or purple, bell-shaped or funnel-shaped.

Sweet potato, also known as sweet potato, sweet potato, yam, etc., is an annual plant of the family Spiraceae.

Sweet potato is an annual plant of the family Dicotyledonaceae.

Sweet potatoes belong to crops, but they do not belong to agricultural products, nor cereal crops, but potato crops in food crops, which are one of the main foods of human beings.

will reduce the sweetness.

Sweet potato is not a traditional crop in China, it is an imported foreign crop.

Sweet potatoes are native to Latin America.

It belongs to a tropical crop that was born in 1492 by Columbus.

After the discovery of the New World in the Americas, sweet potatoes were introduced to Europe and gradually began to spread around the world.

1. Sweet potatoes belong to the family Spiraceae.

2. Planting method: the first choice is the horizontal transplanting method, the fruit of this planting method is more uniform, and the number of sweet potato knots is large, but the only drawback is not drought tolerance, once the rain is more, it will cause a large area of yield reduction. Using direct cultivation, the sweet potatoes grown in this way are generally relatively large.

You can choose the oblique insertion method, which has the highest survival rate of sweet potatoes.

Sweet potato is an annual herbaceous plant of the family Spira, which can grow more than 2 meters, the leaves are generally broadly ovate, the corolla is pink, white, lilac or purple, and there are underground tuberous roots, which are spindle-shaped, and the outer skin is earthy yellow or purplish-red. Sweet potato is also known as red taro, sweet potato, yam, etc., it likes warmth and is afraid of cold, the leaf color is thick when the light is sufficient, the leaf age is long, the stem is thick, and the yield is high. Sweet potato is rich in starch, vitamins, cellulose and other nutrients needed by the human body, and is also rich in magnesium, phosphorus, calcium and other mineral elements and linoleic acid.

Sweet potato type. Sweet potato is a dicot plantate, which is mainly distributed in Beijing, Shanxi, Shandong, Henan, Tianjin, Hebei, Eastern Province, Inner Mongolia, Yunnan Fenghua, Sichuan, Hubei, Gansu, Anhui, Fujian, Shaanxi, Hunan, Guangdong, Jiangsu, Jiangxi, Hainan and other places in China.

Sweet potato attributes. Sweet potato is an annual herbaceous plant of the family Spinaceae, it is a tubular flower, which is also known as red taro, sweet potato, sweet potato, sweet potato, sweet potato, sweet potato, sweet potato, sweet potato.

Sweet potatoes like warmth and cold, like a well-lit environment, when the light is sufficient, the leaf color is strong, the leaf age is long, the stem vine is thick, the stem conduction tissue is developed, and the yield is high.

What does a sweet potato look like.

Sweet potato shape:The fruit of sweet potatoes is the same as that of morning glories, which are round or flat, and in general, one seed in one fruit is round, two seeds are semicircular, and more than three are irregular triangles.

What sweet potato leaves look like:The leaves of sweet potatoes have villi on both sides, denser on the young leaves, the length, width and width vary greatly depending on the cultivation conditions, there are two glands at the junction of the leaves and petioles, and the leaves have many shapes, which are roughly divided into heart-shaped, kidney-shaped, triangular, palm-shaped, etc.

Sweet potato color: The peel of sweet potatoes is green or purple when unripe, withered yellow or brown when ripe, and there are 1-4 yellow silver seeds in each paddle fruit, and the size and shape of the seeds are related to the number of seeds in between.
