Potato planting time is just around the corner. Potato varieties should be selected.

Potatoes are called potatoes locally, and children like them very much. And the yield of potatoes is very high, so it is not only loved by growers, but also welcomed by the market. Potato has become the fourth staple food in China, it can be said that the market is still very good.

Potatoes are very adaptable, so most parts of our country can be planted, but the planting time is also different because of the different climate in different regions. Let's take an example on our side.

Our side is located in the Central Plains. Potatoes are usually planted in spring or autumn. Spring is usually planted in February and March, and autumn potatoes are usually planted in August, which is now the time to start planting.

However, there will be some differences in the planting time of potatoes in other parts of our country. For example, in southwest China, such as Guangxi and Yunnan, potatoes are generally planted during the period from October to November. In Jiangsu and Zhejiang provinces, spring potatoes are planted from January to February and autumn potatoes are planted in September.

Due to the relatively low temperatures in the northeast and northwest regions, potatoes are usually planted in one season from April to May every year. Therefore, the planting time of potatoes varies from region to region. Growers must take into account the characteristics of the local climate to plant according to local conditions.

Here is some more knowledge about potato cultivation.

Potatoes like the cold growing environment, so potatoes have become the staple food of the local people in the cold Nordic region. The most suitable growth temperature of potatoes is about 15 degrees, like loose and fertile sandy soil, the soil needs to be moist.

How to grow potatoes well?

If you want to grow potatoes well, the first step is to grow potatoes. You need to choose potato varieties with good disease resistance. According to the characteristics of the local planting environment, the potato varieties with long growth time are selected, and the varieties with good stress resistance and no disease are needed. When cutting seeds, you need to pay attention to disinfection, if you accidentally encounter bad potatoes, you need to change the knife, or disinfect again. There should be at least two bud eyes on each seed block.

Soil preparation is needed before planting, and potatoes are not tolerant of continuous cropping, which can easily lead to soil-borne diseases. Need to apply sufficient base fertilizer, the general plot of land needs about 3000 kg of organic fertilizer per mu, in addition to about 70 kg of compound fertilizer. When planting, we need to pay attention to the problem of planting density, generally planting 2500 potatoes per mu.

The quality of fertilization directly affects the yield of potatoes in the later stage, generally fertilizing when potatoes grow to about 15 centimeters, usually with ploughing and weeding. It can be topdressing about 5 kg of urea per mu. When potatoes grow to about 40 centimeters, you can apply about 4 kilograms of nitrogen fertilizer for the second time. In addition, potatoes and sweet potatoes belong to potash-loving crops, generally applying about 10 kilograms of potassium sulfate fertilizer during the potato-promoting period.

After entering the flowering stage, potatoes can be applied foliar fertilizer of potassium dihydrogen phosphate every two weeks or so, with a concentration of 0.3%, 9.5%, and generally about 50 kg per mu.
