What are the high-yield cultivation techniques of sowing potatoes in spring? It is very important to do these four points well!

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, many farmers have low yield, which seriously affects the income of farmers. Now that spring is the time to sow potatoes, do you know what are the high-yield cultivation techniques of potatoes? It is very important to do these four points well!

I. seed potato quality of high-yield cultivation techniques of potato

At present, few potato growers across the country use virus-free seed potatoes, which leads to a high incidence of virus diseases in the process of potato cultivation, 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 selection of seed potatoes as far as possible to choose virus-free seed potatoes, and must be strictly regulated, not suitable to use annual potatoes as seeds.

II. Fertilization of high-yield cultivation techniques of potatoes

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, which 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.

Temperature of high-yield cultivation techniques of potatoes

Potatoes have certain requirements on temperature during germination, growth and tuber formation. 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, reducing nutrient consumption can 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.

IV. Diseases and insect pests of high-yield cultivation techniques of potatoes

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 prevention, which shows the harm of diseases and insect pests 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.

Potato planting wants to have a high yield, in addition to natural reasons, but also rely on manpower careful planting and management, in order to have better economic benefits.
