Causes and Solutions of low Potato yield

Potato, also known as potato, is a vegetable we often eat in our daily life, which is distributed all over the country, but with the increase of planting area, the yield of many farmers is low, which seriously affects the income of farmers. So what is the reason for the low potato yield? How to solve the problem, let's take a look at the pro-agricultural network.

1. The quality of seed potato

At present, few potato growers in the country use virus-free seed potato, which leads to the high incidence of virus disease in the process of potato planting, and once the disease is difficult to cure, resulting in a reduction in production. There is the use of potatoes planted for many years, do not introduce new species, resulting in continuous degradation of seed potatoes, but also easy to lead to diseases, resulting in low yield.

Solution: in the choice of heatstroke, try to choose virus-free seed potato, the selection of medium potato must be strictly regulated, it is not suitable to use annual potato as seed.

2. Improper fertilization

In order to save the planting cost, many farmers only apply chemical fertilizer, seldom apply organic fertilizer or farm manure, and the amount of fertilizer is seriously insufficient, which leads to the lack of nutrients and the normal growth of potatoes. it also leads to low yield.

Solution: fertilizer must be fully applied, generally the amount of fertilizer per hectare is 250~400kg, and try to choose farm manure and organic fertilizer with chemical fertilizer to ensure the nutrients needed for potato growth.

3. Temperature reason

Potato has certain requirements on temperature during germination, growth and tuberization. During germination, the temperature should be kept at 7-12 degrees. In the planting and growth stage, the most suitable temperature for growth is 18-22 degrees. Once the temperature is above 35 degrees or below 7 degrees, it will stop growing. When the temperature is below minus 3 degrees, the plant will freeze to death. The most suitable temperature for tuber is 16-20 degrees. When the temperature difference between day and night is large, it can reduce nutrient consumption and increase production to a certain extent, but when the night temperature is higher than 25 degrees, it will stop growing and cause yield reduction.

Solution: so must follow the temperature of potato growth, the temperature can not be too high or too low, in tuber, if the temperature difference between day and night is small, you can use greenhouse technology to increase the temperature difference, seal the greenhouse during the day, increase room temperature, and strengthen ventilation at night. Lower the room temperature.

4. Causes of diseases and insect pests

Diseases and insect pests have a great impact on the quality and yield of potatoes, according to the data survey shows that the use of drugs to prevent diseases increased by 34.7% compared with those without disease control, which shows that diseases and insect pests are harmful to the yield of potatoes. In addition, when planting in the mountain area, it is seriously damaged by 28 lady beetles, and it will compete with the plant growth for nutrients during the grass famine period, and the rodent damage to the potato yield should not be underestimated.

Solution: the prevention and control of diseases and insect pests during planting should not be ignored, strengthen daily management, increase the application of phosphorus and potassium fertilizer, improve plant disease resistance, timely treatment of diseases and insect pests, and prescribe the right medicine.

The above are the reasons and solutions for the low potato yield brought by the pro-agricultural network. I hope it can help you. If you want to know more, please pay attention to the pro-agricultural network.
