How many kinds of potatoes do you need for an acre of land? What is the yield per mu?

Potato is one of the main food crops in the world, which is not only difficult to grow, but also has a high yield, but also has a wide range of planting in the world. How many kinds of potatoes does it take to grow an acre of land? What is the yield per mu? Let's get to know it together.

I. the basic situation of potatoes

1. The origin of potatoes

The scientific name of potato is potato. In some areas, it is also called potato, Dutch potato, ground egg, potato, potato, Dutch potato, sweet potato and so on. In France, it is also called "underground apple". Its main producing countries include Russia, Poland, China, the United States and Mexico. Among them, the main potato producing areas in China are southwest mountain areas, northwest, Inner Mongolia and northeast regions.

two。 The value of potatoes

Potatoes are rich in starch, protein, fat, crude fiber, etc., eating can enhance the sense of fullness, can help take away some oil and garbage, has a certain role of defecation and detoxification. And potatoes have certain anti-aging, thin legs and other effects; potatoes can also be used to treat stomachache, ribs, carbuncle swelling, eczema, scald and other symptoms, is and stomach health medicine and detoxification detumescence medicine, but also high-quality health products for patients with stomach disease and heart disease.

2. How many kinds of potatoes do you need for one mu of land?

Because potatoes can be propagated by tubers or seeds, the kinds of potatoes needed per mu are also different. It is appropriate to plant 4000 holes per mu, and the best seed potato is 50MUE 75g, and the seed amount per mu is 200MUE 300kg. When planting, you should pay attention to:

1. If the potato tuber is used for asexual propagation, the seed potato can germinate and grow under the condition of soil temperature 5-8 ℃, and the optimum temperature is 15-20 ℃. The suitable temperature for stem and leaf growth and flowering is 16-22 ℃. The most suitable temperature for tuber formation at night is 10-13 ℃ (soil temperature 16-18 ℃), but it forms slowly when it is higher than 20 ℃.

two。 If the seeds are sown, the seeds should be treated and germinated in advance and planted in February-March or August of each year.

What is the yield of potatoes per mu?

Potato has a high yield and is easy to manage, so it is one of the important food crops. Generally speaking, its yield per mu is about 1000 jin. Before Pingyi, Shandong Province, potatoes with a yield of 5500 jin per mu were planted. If you want to get high-yield growers, you should pay attention to the following points:

1. Potatoes should be sowed at the right time and planted reasonably.

Potatoes are generally planted in spring, sowed from the end of February to the first ten days of March, and harvested from the end of May to the middle of June. Plastic film mulching is carried out when sowing, and the way of row spacing 60cm, plant spacing 25cm, or row spacing 70cm, plant spacing 20em is adopted. It is appropriate to keep the density at 4000-4500 plants per mu.

two。 Fertilizing and topdressing potatoes can not be less.

80-100 kg of biological fertilizer can be used as base fertilizer. Dig a good planting hole to plant seed potato, and then evenly spread biological bacterial fertilizer next to the seed potato, and finally cover the seed potato and biological bacterial fertilizer; in addition, it is necessary to apply certain biological bacterial fertilizer in the period of growth and development and fruit expansion.

3. Prevention and control of potato diseases and insect pests should be timely

During the growth of potatoes, attention should be paid to the invasion of diseases and insect pests such as ring rot, virus, 28 ladybugs and grubs, and timely detection and treatment should be made to prevent the expansion of disease scope and affect yield.
