How to grow potatoes

Before planting potatoes, the seeds should be placed in scattered light half a month in advance to promote germination. After sprouting, cut into small pieces with a knife, and then sow them into the deep ditches of 15cm according to the distance between 25cm and 30cm. Finally, cover with a layer of manure, sprinkle some urea, and cover the soil. When slicing, each potato should have two to three sprouting points, so as to improve the germination rate.

What are the matters needing attention in potato planting?

1. Time

There is a great difference in the climate between the north and the south of our country, so there will be some differences in the time of planting potatoes, but generally they are planted every year in autumn and winter, that is, around October to December, but with the development of planting technology and science and technology, many places can basically be planted all the year round, but according to the growth habits of potatoes, it is best to sow early at the right time. Otherwise, the growth and development of potatoes will be affected.

2. Sprouting

About half a month before sowing, we should sprout the selected potato seeds where there is a certain amount of light, avoid direct sunlight, and keep the temperature of the budding place at about 15-20 degrees Celsius. If there is no cellar, we can do it directly in the disaster prevention cellar, because the temperature in the cellar is relatively high, and the bud point had better be about 0.2cm, not more than 0.5cm. Otherwise, it is easy to damage the bud point when cutting into pieces.

3. Cut into pieces

The slicing in the potato book is not random. We must ensure that each potato must have two or three bud points, so as to ensure its emergence rate. Under normal circumstances, we cut the potato the day before sowing. Under conditional conditions, a potato can only be cut into four pieces at most. At the same time, it is necessary to ensure that the sprout point of the potato is not destroyed and sterilized with alcohol.

4. Sowing seeds

Sowing should mainly pay attention to the potato block planting depth and planting density, in general, the best planting depth is about 15cm, according to the bud point upward way, the potato block according to 60-70cm per row, each plant 25-30cm interval planting, and finally with a layer of thin soil serious, while covering a layer of agricultural plastic film to promote seedlings.

5. Temperature

There are requirements for potato planting temperature, the most suitable temperature for potato growth is between 15-20 degrees, and it can sprout normally at about 5-8 degrees, but potato branches and leaves growth and flowering temperature generally reach 18-25 degrees, the temperature at night should also be about 12-15 degrees, the temperature difference between day and night should not be too big. So we should have a general understanding of the temperature in the field and manage it scientifically.

6. Fertilizer and water

The most fertilizer needed for the growth of potatoes is potash fertilizer, then nitrogen fertilizer, and finally phosphorus fertilizer, but it is best to apply some farm manure or organic fertilizer before applying chemical fertilizer. in this way, the moisture and fertilizer effect of the soil and the soil structure can be improved to a certain extent, so as to promote the growth of potato, at the same time, we should pay attention to water management. Potato needs a lot of water in its growing period and flowering period, but it is not easy to have too much water, otherwise it will cause soil consolidation and affect the growth of potato underground tubers.

7. Cultivate the soil

It is very important to cultivate and loosen the soil in the process of potato growth, because if his tuber is to expand, then the underground soil should be relatively loose, and the soil permeability should be better, and the ability to absorb nutrients should be stronger at the same time. So it is necessary to cultivate and loosen the soil at least 4-5 times during its whole growing period, so that the potato tubers planted will be more full.

The above is the introduction of how to grow potatoes. I hope it will be helpful to you.
