How can potatoes produce high yield?

Potato is one of the most widely planted food crops in China. Recently, the price of potatoes is getting higher and higher, and the planting area is also getting wider and wider. Although there are many people growing potatoes, but the final output is still not satisfactory, not to the extent they imagined. Well, today, the editor has brought you several conditions for the high yield of potatoes. Let's take a look.

1. Seed selection

Seed selection is a prerequisite to ensure high yield of potatoes, but now many farmers still remain in the planting concept and quality of more than ten years ago, planting the same variety for more than ten years. Although many people have changed varieties during the planting period, the soil planted has not been updated, resulting in serious degradation of the quality of the varieties. The variety of potatoes should be selected according to planting environment, time, weather and other factors. Also consider the market demand and season, as long as according to these circumstances to select varieties can get a very good yield.

2. Raising seedlings

Potato cultivation will be easy to rot if the weather is high or low and the temperature is uncertain, so when sprouting, it is necessary to ensure that the seedlings are complete, Miaoqi and other conditions. Select the disease-free medium beans with relatively uniform budding eyes, cut them and dry them, put them in a shady place, spread a layer of moist sand, and then cover them with plastic film for heat preservation. Generally speaking, the sprouting eyes of potato blocks will begin to sprout in 1-2 weeks, and those that have already germinated will be sown, and those that have not yet germinated will continue to germinate.

3. Temperature

Potatoes have a great demand for light, but they are strict with light and temperature. 20 degrees is the most suitable temperature when potatoes are young. Potato tuber growth temperature should be controlled at about 18-20 degrees, higher than 20 degrees, less than 18 degrees will try different effects on the growth and development of potatoes. For example, according to the weather and farming conditions in the south, sowing begins around the Beginning of Autumn, and harvest can begin in November. After harvest, winter seeds can be sown, and the following year around the Beginning of Spring can harvest. And then follow this list. Spring seeds can be harvested from May to June.

4. Cultivation

Potatoes will grow faster in the later stage, so the soil for growing potatoes must choose rich, deep and soft soil. The drainage system is good. The field is divided into a ridge and a ridge, with a width of 70-80cm and a height of 30-40cm. Mainly according to the variety to select different field beds, reasonable control of planting density, generally the distance of each hole in 25cm, row spacing in 30cm. And because the growing period of potato is shorter than that of other crops, it is necessary to ensure its fertilizer requirement.

The above are several conditions for the high yield of potatoes sorted out by the editor, as long as the varieties, seedlings and other four aspects are done well, it is not difficult to achieve high yield. As long as you are careful, observe the situation of potatoes, deal with diseases and insect pests in time, and ensure the amount of fertilizer needed by potatoes, you will be able to ensure your own economic interests.
