High-yielding cultivation techniques of planting potatoes in Spring

Potato is a vegetable that we often eat in our daily life, which is distributed all over the country, and with the increase of planting area, many farmers have the phenomenon of low yield, which seriously affects the income of farmers. Spring is the time when potatoes are sown, so what can be done to achieve high yield? Let's get to know it with the editor.

1. Seed potato quality

At present, few potato growers across the country use virus-free seed potatoes, which leads to potato diseases becoming more and more frequent and serious year by year, and it is extremely difficult to cure after the disease, resulting in a reduction in production. Many people use potatoes planted for many years without introducing new species, which results in continuous degradation of seed potatoes, which can easily lead to diseases and low yield. And the solution is relatively simple, is to choose virus-free seed potatoes as far as possible, and once it is strictly regulated, it is not suitable to use potatoes to make seeds year after year.

2. Temperature management

Potatoes have certain requirements for temperature during the germination, growth and tuber formation period, and the temperature should be kept between 7-12 degrees during the germination period, while in the process of planting and growth, the most suitable growth temperature is between 18 and 22 degrees. Once the temperature is more than 35 degrees or less than 7 degrees, will stop growing, when the temperature is below minus 3 degrees, the plant will directly freeze to death. The most suitable temperature for potato growth is 16-20 degrees. When the temperature difference between day and night is large, the nutrient consumption is reduced, which can increase production to a certain extent. When the night temperature is higher than 25 degrees, it will stop growing and reduce production. Therefore, when planting, we must follow the potato growth temperature, should not be too high or too low, tuber as far as possible to open the temperature difference between day and night.

3. Fertilization

In the process of planting, in order to save nutrients, many farmers only apply chemical fertilizer, seldom apply organic fertilizer and farm manure, and the amount of fertilizer is seriously insufficient, which will cause potatoes to lack nutrients in the process of growth and can not grow normally. It will also lead to low yield. So fertilizer must be fully applied, generally 15-25 kg per mu, and try to choose farm manure and organic fertilizer mixed with chemical fertilizer to ensure the growth of potatoes.

4. Pest control

Diseases and insect pests affect the yield and quality of potatoes, especially when planted in mountainous areas, they are seriously damaged by 28 lady beetles, and they compete for nutrients with plant growth during grass famine, and the yield of potatoes can not be underestimated by rodent damage. When planting, the prevention and control of diseases and insect pests should not be ignored, strengthen daily management, increase the application of phosphorus and potassium fertilizer, improve plant disease resistance, find timely treatment of diseases and insect pests, and prescribe the right medicine.

The above is the introduction of high-yield cultivation techniques of planting potatoes in spring. I hope I can help you. If you want to know more about it, please follow us.
