Recently, some farmers have consulted in the background of Huinong. Is the potato output low? We must know that China is a big country for potato cultivation, and it is distributed in all regions. If the potato yield you plant is low, you can consider the following points.
First, the seed potato problem
Nowadays, many people still use the potato planted for many years. This kind of seed potato has been degraded, and now it is more popular with virus-free seed potatoes.
Solution: It is recommended that the seed potato should choose the virus-free seed potato as much as possible. The selection of the seed potato must be strict. Do not use the potato planted for many years.
Second, improper fertilization
In order to save costs, many growers apply only one type of fertilizer when fertilizing, and the amount of fertilizer is still seriously insufficient. This leads to the lack of nutrients of the potato, the inability to grow normally, and the yield is certainly not high.
Solution: When fertilizing the potato, it must be fully applied. Usually, the dosage of fertilization per acre is 250 to 400 kg. It is also the application of organic fertilizer and farmyard manure with chemical fertilizer.
Third, temperature reasons
The temperature requirements of different stages of the potato are different. It needs to be maintained at 7 to 12 degrees during germination and 18 to 22 degrees during growth and development. Once the temperature exceeds 35 degrees or below 7 degrees, the potato will stop growing. When the temperature is below zero, the potato plants will freeze directly to death. Generally, the most suitable temperature for potato is between 16 and 20 degrees.
Solution: Potato growth must be maintained at a suitable temperature. Too high or too low is not right. If the temperature difference between day and night is small, you can also use greenhouse technology to control temperature.
Fourth, pests and diseases
Pests and diseases have a great impact on any crop, and the impact of rodents and pests on potato yield should not be underestimated.
Solution: Therefore, in the process of planting potatoes, we must strengthen the usual management, increase the application of phosphorus and potassium fertilizer, improve the disease resistance of potato plants, and find that pests and diseases must be treated in time, the right medicine.
The above is the reason for the low yield of potato and its solution. You can look at these reasons. If you have other reasons to add, please let us know below!
