Purple sweet potato has anti cancer effect, how to control the planting density?

<> sweet potato and purple sweet potato are both sweet potato annual herbaceous plants, both are economic crops, and the planting methods are basically the same, both of which are cultivated by cuttings after seedling propagation; However, purple sweet potato is a special variety of sweet potato, its growth habits, planting time, management technology, etc., can also be cultivated, which can increase the active soil layer, keep the soil loose, and increase the number of potato nuggets.

<> give purple potatoes good conditions for expansion and creation. Plastic film cultivation can plant purple potatoes in advance, promote early maturity for more than 15 20 days, effectively increase the yield of purple potatoes, can be sold at a good price, and increase economic benefits. Sweet potato is a general term for potatoes, which also includes purple potatoes.

Only purple potato was introduced into China from Japan around 2000, and after breeding and cultivation by domestic scientists, it is a fruit-type variety potato with purple skin and purple flesh. It has a delicate and sweet taste, high sugar content, rich in trace elements selenium, suitable for sweet potatoes, and can be divided into purple potatoes from the color of the tubers.

White sweet potato, yellow sweet potato and watermelon sweet potato. For the cultivation of sweet potatoes, the method should be the same, almost, just a new variety of sweet potato. It's hard to distinguish the seedlings in the field, but the color of the potato pieces is different, and the taste is a little different, like apples and peaches are sweet and sour.

In planting, we raise seedlings and plant together with other sweet potatoes, and there are several varieties of sweet potatoes planted in recent years. However, it should be noted that different varieties of sweet potatoes are best grown separately.

The sound of roasted sweet potatoes and the fragrance of sweet potatoes wafting out, every time you smell the sweet potato, you can always arouse the "gluttony" in your stomach, even if you have just finished lunch, you can't help but buy one.

In terms of nutrition, it is more nutritious than sweet potatoes.

Although it is highly nutritious, it is rarely cultivated in rural areas, and there is no experiment in growing purple potatoes.

The planting density should be controlled at about 18 cm, after planting, it is necessary to water the root water to improve the survival rate of potato seedlings, and regularly check the seedlings, if the lack of seedlings is found, it is necessary to replenish the seedlings in time.

In fact, the best way to control density is to be a little farther away when you are heavy, and then you should master the distance when you are usually grafting, so that you can control the density well.

Choose fertile land for purple potato planting, before planting, deep ploughing 25 cm, and apply rotten farmhouse fertilizer and compound fertilizer, level the land, ridge, keep the row spacing 60 cm, the temperature is above 15 degrees, planting, when planting, the potato seedlings should be inserted diagonally into the planting field, there are two knots on the ground, 3500-4000 plants can be planted per mu, and the plant spacing is controlled at about 18 cm.

The planting density is about to control the planting of 3500-4000 delayed purple potato seedlings in one acre, and the distance between each seedling can be kept at about 16-18 cm, and the distance between the ridges can be controlled at 17 cm. Toshiga.

The planting density is generally 4,000 plants and 667 square meters, depending on the size of the planting land area, which is adjusted according to the area.

The density should be smaller, and 10 kg of purple potatoes need to be planted on one acre of land, and the seedlings must be raised before cutting.

The planting density of purple potatoes should be 30 cm per plant, so that they will not affect each other, and they can also be better watered and fertilized.

The distance between each row is 30 cm, and the distance between each plant is cm, which is very suitable for purple potato growth.

The planting density of purple potatoes can be higher, and the row spacing can be controlled at 20cm, and the plant spacing can be controlled at 15cm.

Purple potatoes are only different from ordinary sweet potatoes in terms of internal nutrient distribution, and they are the same in terms of cultivation technology.
