Potato planting requirements and management points
How is the potato planted? It is not difficult to say that potato cultivation is easy. It is not easy to say that it is easy. It is the key to the high yield of potato cultivation, the soil requirements of potatoes, the demand for water and the temperature suitable for growth. Let's take a look at it together.
First, potato soil planting requirements
Potatoes are generally suitable for planting on sandy soil. The requirement of potato for soil planting environment is that the drainage is good and the soil permeability is strong, because it can avoid the occurrence of pests and diseases and reduce the incidence of hypoxia in the roots.
If it is planted in sticky soil, the water retention capacity is relatively strong. When the weather temperature is low, the soil is not easy to emerge due to wet and cold, so if this situation is encountered, it should be properly shallow and high ridges, so that it can facilitate water discharge in the future. It is also possible to use farmyard fertilizers and to add some sand to the soil before sowing, which can play an improved role.
Second, the potato lighting needs
When the potato enters the flower bud differentiation stage, the light time needs to be lengthened so that the water can bloom. At the same time, the light also determines the growth height of the plant. The light intensity required for different growth stages is also different.
For example, in the germination period, short days can avoid growing thin and high seedlings. In order to enhance the growth of stems and leaves in the hair growth period, photosynthesis needs to be enhanced, so the light time should be prolonged. Into the rhizome expansion period, it is necessary to inhibit the growth of stems and leaves, increase the temperature difference between day and night, in order to promote starch accumulation, lay a good foundation for high yield, and this period is more inclined to short sunshine. Potatoes have different water requirements during different growth stages.
Third, the management of potato germination period
In fact, the amount of water required for germination is small, and water remains in the seed potato block, which is enough to maintain the growth of the seedlings. Keep the soil from being too wet, otherwise the permeability will be poor. The development of the root system at the seedling stage is very important, and it should not be too moist, but it requires more water than the germination period. During the growing period, the growth rate of stems and leaves is accelerated, and the demand for water is extremely high. If it is too dry during the potato-forming period, it will affect the final yield, so don't let it dry.
Fourth, water and fertilizer management
Drought has a great impact on the crop. It will first inhibit root growth, affect the absorption of nutrients by plants, reduce the efficiency of photosynthesis, and easily hinder the growth of tuber parts and even grow deformities. Studies have found that if sufficient water is given during tuber growth, the starch content can be increased, even in arid climates, as long as regular irrigation, there is still a higher yield. If the irrigation conditions are insufficient, it is necessary to consider improving the drought resistance of the potato, and the rational use of potassium fertilizer can have a good effect.
Fifth, potato temperature requirements
Potatoes have different requirements for temperature at different times. They can germinate above seven degrees. When the temperature climbs to a dozen degrees, the growth rate of seedlings increases. Temperature is too high is not good, although the small buds seem to grow faster, but easy to slender and thin, poor disease resistance, and ultimately affect the yield and quality.
The above is the planting characteristics of the potato. Let's see what else needs to be added. Of course, the above content is only for the reference of the growers and friends. More professional and technical knowledge can continue to pay attention to this site.
