How much seed potato is needed per mu of land, and what is the yield per mu?
The potato is one of the world's major food crops. It is not only easy to grow but also high-yielding, and it is grown across a very wide range worldwide. So how much seed potato is roughly needed to plant one mu of land? What is the yield per mu? Let's find out together below.
1. Basic facts about the potato
1. The origin of the potato
The scientific name of the potato is Solanum tuberosum. In some regions it is also called yam, Dutch potato, earth egg, spud, potato, Dutch potato, foreign potato and so on, and in France it is even called the “underground apple”. Its main producing countries include Russia, Poland, China, the United States and Mexico. Among them, China's main potato-producing areas are the mountainous region of the southwest, the northwest, Inner Mongolia and the northeast.
2. The value of the potato
The potato is rich in starch, protein, fat, crude fiber and so on. Eating it increases the feeling of fullness, can help carry away some grease and waste, and has a certain effect of promoting bowel movements and detoxifying. The potato also has a certain anti-aging effect and can help slim the legs; the potato can also be used to treat symptoms such as stomach pain, mumps, boils and swelling, eczema and burns. It is a medicine for harmonizing the stomach and strengthening the body and a detoxifying and swelling-reducing medicine, and it is also a high-quality health product for patients with stomach problems and heart disease.
2. How much seed potato is roughly needed for one mu of land?
Since the potato can be propagated by tuber or by seed, the amount of seed potato needed per mu is also different. A planting density of 4000 hills per mu is suitable, and seed potatoes of 50-75 grams are best, so the seeding rate per mu is 200-300 kg. When planting, pay attention to the following:
1. If the potato is propagated asexually by tuber, the seed potato can germinate and grow at a soil temperature of 5-8°C, with the optimum temperature being 15-20°C. The air temperature suitable for the growth of stems and leaves and for flowering is 16-22°C. The air temperature most suitable for tuber formation at night is 10-13°C (soil temperature 16-18°C), and when it is higher than 20°C, formation is slow.
2. If sowing with seeds, the seeds must first be treated and pre-germinated, and planting is carried out in February to March or in August each year.
3. What is the potato yield per mu?
The potato is high-yielding and easy to manage, and it is one of the important food crops. Generally its yield per mu is about 1000 jin, and in Pingyi, Shandong, a potato yield of 5500 jin per mu was once achieved. Growers who want to obtain a high yield should pay attention to the following points:
1. Potatoes should be sown at the right time and planted reasonably
Potatoes are generally planted in spring, sown from the end of February to early March and harvested from the end of May to mid-June. When sowing, plastic film mulching is used, with a row spacing of 60cm and a plant spacing of 25cm, or a row spacing of 70cm and a plant spacing of 20em, and the density per mu should preferably be kept at 4000-4500 plants.
2. Fertilizing and topdressing potatoes cannot be omitted
80-100 kg of biological bacterial fertilizer can be used as a base fertilizer. Dig the planting holes and plant the seed potatoes, then evenly spread the biological bacterial fertilizer beside the seed potatoes, and finally cover with soil so that the seed potatoes and the biological bacterial fertilizer are completely covered; in addition, a certain amount of biological bacterial fertilizer should be applied as a topdressing during the growth and development period and the fruit-swelling period.
3. Potato pest and disease control must be timely
During the potato growing period, pay attention to attacks by pests and diseases such as ring rot, viral disease, the 28-spotted ladybird and white grubs, and detect and treat them promptly to prevent the scope of the disease from expanding and affecting the yield.
