Have you ever eaten red potatoes? The origin of red-skinned potatoes is in South America, and the outer skin is red. The red-skinned potatoes are rich in trace elements and have a series of effects such as anti-oxidation, anti-cancer and blood pressure lowering. The taste of red potatoes is also softer than ordinary potatoes. Let's take a quick look at how to grow red potatoes.
First, land selection, land preparation
The soil for planting red potatoes must first be kept loose, because the tubers of red potatoes are large, the consumption of oxygen is large, and the soil that is loose enough is highly permeable. The pH value of soil is generally controlled at about 5.2 to 7.8, and the salt-tolerance of red-skinned potatoes is still strong. The plot should be chosen where the terrain is high and the drainage is good, followed by land preparation, and the depth of the land preparation should not be less than twenty-five centimeters.
Second, selected, sowing
In the process of planting red-skinned potatoes, the base fertilizer should be applied to the whole land. The base fertilizer is usually based on fully-fertilized farmyard manure. The dosage per mu is controlled at about 2500 kg, and it can be evenly sprinkled.
After the site preparation, the red-skinned potatoes with smooth surface and high disease resistance should be selected for seeding. The seedlings can be placed indoors for half a month before sowing, so that the stems enter the germination stage, and the temperature of the local surface rises to octave after germination. The above can be sown, usually before and after the Ching Ming Festival, when planting, please control the seeding density, can not be too dense, too dense will cause plants to block each other, affecting photosynthesis.
Third, fertilizer management
Red-skinned potatoes are planted in the water, which requires a large amount of water. Generally, it needs to be watered more than five times during the growth period. The watering method is generally based on small water droplets.
When the red-skinned potato seedlings were unearthed, everyone remembered to water them in time. It is necessary to water more water during the bud period and flowering period. In the process of planting red-skinned potatoes, it is necessary to topdress in time. The demand for potash fertilizer is higher in red-skinned potatoes. When topdressing, we can increase the proportion of potassium in an appropriate amount. The main period of top dressing is in the expansion period, the bud stage and the tuber formation stage.
Fourth, field management
The loose enough soil is very important for the growth and formation of red potato tuber. Of course, the cultivating and weeding work is also very important. Generally, the first weeding can be carried out after the seedlings. The flower buds of red-skinned potatoes have little effect. They can also take away the nutrients from the tubers and can be removed. Pay attention to the time when removing them. When the 28-year-old flower buds of the red-skinned potato plants are in full bloom, they must start to remove the work. It’s about twice a week.
The above is the cultivation method and key points of red-skinned potatoes. You can learn reference with Xiaobian. If you want to learn other agricultural techniques and knowledge, you can continue to pay attention to Hui Nongwang!
