Potato planting precautions

Potato is widely planted in China, and it is a relatively important grain in the world, with high nutritional value, and its nutrients are easily absorbed by the human body. Aziger is also very close to the people in the market. the ability to use the environment is very strong, and it is relatively simple to plant, but some growers report that the quality and yield of potatoes are not high. That's because there are a lot of things they didn't pay attention to when they were planting. Let's take a look at it.

1. Time

There is a big 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 they are generally 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 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 to 20 degrees Celsius. If there is no cellar, you can directly sprout in the disaster prevention cellar, because the temperature in the cellar is relatively high, and the bud point had better be about 0.2 cm, not more than 0.5 cm. 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

The main thing to pay attention to in sowing is the planting depth and density of potato blocks. in general, the best planting depth is about 15 centimeters. According to the way that the bud points are facing up, the potato blocks are planted at an interval of 60 to 70 centimeters per row. Each plant is planted at an interval of 25 to 30 centimeters. Finally, it is serious with a layer of thin soil. At the same time, it is covered with a layer of agricultural plastic film to keep warm and accelerate seedlings.

5. Temperature

Potato has requirements on the temperature of planting, the most suitable temperature for potato growth is between 15 and 20 degrees, and it can sprout normally at about 5 to 8 degrees. However, the growth of branches and leaves of potatoes and the temperature of flowering period are generally between 18 and 25 degrees, and the temperature at night is about 12 to 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 four to five times during its whole growing period, so that the potato tubers planted will be more full.
