Key Technical Points and Management Methods for Winter Potato Planting
Potatoes are cold-tolerant and can also be planted in winter. However, if the temperature is too low in winter, potatoes will not sprout well, so it is still necessary to do a good job of frost protection. So what are the techniques for winter potato planting?
1. Control of planting temperature
Potatoes are cold-tolerant, but potato seeds also need temperatures above 0 degrees to germinate. If the temperature is below 0 degrees, the seeds will freeze to death and will not be able to sprout.
If you want to plant in winter, the local temperature must be above zero before planting. If the temperature is too low, you can also plant in a greenhouse. Planting in a greenhouse also requires frost protection, and greenhouse management must be done well, such as ventilation and covering with plastic film, etc.
2. Sprouting seed potatoes
Because potato seed potatoes have the characteristic of dormancy, and some seed potatoes have a longer dormancy period, if seed potatoes in a dormant state are sown, they are not easy to sprout, resulting in uneven germination and emergence, or even seed rot. Therefore, seed potatoes need to be sprouted.
3. Covering with plastic film
When planting potatoes in winter, the soil temperature is very low. Because the weather is too cold, planting potatoes still requires covering with plastic film to keep warm. If planting potatoes in the open field, it is best to plant them a bit deeper when planting, at a depth of about 10 cm, which can also help keep them warm.
4. Field management
Field management mainly consists of loosening the soil and weeding. Loosening the soil can make the soil loose and breathable, allowing potato seedlings to root better and absorb nutrients better, so the potatoes can grow larger. Weeding is mainly to prevent weeds from competing with potatoes for nutrients, which is not conducive to potato growth.
