Winter potato management points and precautions
Recently, many novice growers have asked questions about the winter potato planting points. It is well known that potatoes are more resistant to cold and can be grown in winter. However, it is important to make clear that potato winter planting also needs to pay attention to some details. Let's take a look at it briefly.
First, temperature control
Potatoes are cold-tolerant, but potato seeds germinate and need to be above 0 degrees. If the temperature is below 0 degrees, the seeds will be frozen and the buds will not be produced. If you want to plant in the winter, the local temperature must be planted at a temperature above zero. If the temperature is too low, it can also be planted in a greenhouse. It is also necessary to prevent freezing in the greenhouse. It is also necessary to do the management of the greenhouse, such as ventilation, such as covering the mulch film.
Second, the choice of land
For potatoes, it is best to choose fertile, loose and breathable soil. It is better not to have planted potatoes before. If the last mash has been planted with potatoes, this mash will replant the potatoes, the pests and diseases will be very serious, and will affect the yield of the potatoes.
Third, soil preparation and fertilization
After the land is well prepared, it is necessary to apply the base fertilizer. The bottom fertilizer is best for farmyard manure, and the farmyard manure can also make the soil loose and breathable, and is more suitable for the growth of potatoes. It is necessary to pay attention to the farmer's fertilizer, and then get into the ground after the rot is good. If you put the raw fertilizer directly into the ground, there will be root burning, which is not good for the growth of potatoes.
Fourth, covering the mulch
Potatoes are grown in winter and the temperature of the soil is very low. Because the weather is too cold, it is necessary to cover the mulch to keep the potatoes warm. If you are planting potatoes in the open air, it is best to grow a little deeper when planting, and the depth is about 10 cm, so you can keep warm. After the potatoes are planted, it is also possible to cover the mulch or cover some hay. After the potato seedlings are out, remove the cover and let the potato seedlings enjoy the light.
V. Water and fertilizer management
In order to make potatoes safe for the winter, the management of water and fertilizer should also be in place, so that the potatoes themselves grow stronger and their resistance is enhanced. It can also prevent freezing. In this aspect of management, we must pay special attention to the problem of fertilizers. The amount of nitrogen fertilizer should be moderate. If there is more nitrogen fertilizer, there will be a prolonged phenomenon. There is also a key stage to pay attention to, that is, when the potato pieces start to grow, this stage requires more fertilizer, and more fertilizer.
6. Field management
Field management, mainly loosening soil and weeding, loose soil dragon can make the soil loose and breathable, can make the potato seedlings take better roots, better absorb nutrients, potatoes can grow bigger. Weeding is mainly to prevent weeds from competing with potatoes for nutrition, which is not conducive to the growth of potatoes. These two aspects of work must be done regularly to ensure that the field is clean.
Seven, prevention of pests and diseases
Regarding the prevention and control of pests and diseases, the effect of prevention in advance will be better than the effect of prevention and treatment, so it is necessary to spray some drugs in advance for prevention. Once the pest has occurred, treat it promptly.
