Cultivation techniques of sweet potato with ten thousand jin

Prepare a piece of sandy soil, turn it deep and apply sufficient basic fertilizer to make a ridge with wide 70cm and high 20cm. Then some healthy, high-yield and high-quality sweet potato varieties were cut into small pieces and planted on the field ridge according to the distance of 30-60cm. Finally, the soil was covered with rotten manure and covered with film. After sprouting, the basic management work such as water and fertilizer, ploughing and soil cultivation, pest control and so on can produce a high yield of 10,000 jin.

Ten thousand jin cultivation techniques of sweet potato are explained in detail:

First, select excellent varieties of high-quality potato seedlings

First of all, high-yield sweet potato can not be separated from high-quality sweet potato seedlings, high-quality sweet potato seedlings can increase yield, early fruiting and strong disease resistance. High-quality sweet potato seedlings are generally short internodes, three to five nodes, and the seedling height is 20 to 30cm.

Second, advocating ridge cultivation

Small ridges are generally cultivated in a single row, with a ridge distance of 70 cm and a ridge height of 15 to 20 cm, while large ridges are cultivated in two rows, with a ridge distance of 85 to 95cm, and a ridge height of 25cm.

Pay attention to the application of potash fertilizer

Sweet potato as a high-yield crop variety, there is also a lot of demand for fertilizer, of which potash fertilizer is the greatest demand. The fertilization principle of sweet potato is mainly potassium fertilizer, proper amount of nitrogen fertilizer and the combination of potassium and phosphorus.

Fourth, use plastic film to plant early at the right time

Plastic film can be planted early at the right time, which can prolong the growth period of sweet potato and increase the accumulation of nutrients.

5. Improved horizontal planting

Improved horizontal cutting is to make sweet potato seedlings into the soil more nodes, so that the consumption of nutrients and water will be less, the slow seedling time will be shorter, and the survival rate of planting will be improved.

The above is the introduction of ten thousand jin cultivation techniques of sweet potato. I hope it will be helpful to everyone.
