How many pounds of potato are generally produced per mu? Planting techniques for producing 10,000 pounds per mu

Potato yield per acre

Generally speaking, the potato yield per mu is about 2,000 kilograms. Good land and reasonable management can make the yield per mu reach more than 5,000 kilograms. Potatoes can be planted twice a year. Usually after sowing in spring, they can be planted again around August, and harvested twice a year.

Potato planting prospects

The input cost of potato per mu of land is about 2,500 yuan, the investment in agricultural materials such as pesticides, fertilizers, and watering is more than 1,000 yuan, the fuel, maintenance, and labor costs of agricultural machinery are also about 1,000 yuan, and the land rent is 300-400 yuan, so the cost is about 2,500 yuan.

The market price is 2.5 yuan per catty. Based on the yield of 3,000 catties per mu, the net profit is about 5,000 yuan. Potatoes can not only be eaten as vegetables, but can also be made into a variety of snacks. Although the price is not as high as new crops, the planting prospects are good and the economic benefits are high.

How to grow potatoes for high yield

1. Land preparation and fertilization

When planting potatoes, you should choose sandy loam land that is loose and breathable, has convenient irrigation and drainage, is rich in organic matter, has a flat terrain, a thick and fertile tillage layer. Prepare the land after the previous crop is harvested, and combine cultivation with fertilization before planting.

2. Seed selection and processing

Choose high-yield virus-free potatoes with intact tubers, no frostbite, no pests and diseases, shallow buds and smooth skin as seed potatoes, such as Kexin No. 1, Feureta, Donnong 303, Zaodabai, Eugene and Kexin No. 6. Cut the tubers 3-5 days before sowing, mix them with talcum powder and methyl thiophanate, and dry them for later use.

3. Sowing method

When the daily average temperature is 15 to 25℃ or the temperature of the soil layer 10 cm high is above 10℃ for more than 3 days, you can sow. When sowing, arrange the planting density reasonably according to the variety and soil fertility. Under normal cultivation conditions, 120 to 150 kg of seeds are used per mu of potato.

4. Moisture management

Water the potatoes in time after sowing to keep the soil moist and ensure germination. The frequency of watering can be increased during the plant growth, bud formation and flowering stages to ensure sufficient water in the soil. When the stems and leaves stop growing, the demand for water will increase and attention should be paid to watering to prevent late maturity of the potatoes or reduce yield.

5. Disease prevention and control

If diseases occur during potato growth, it will lead to reduced yields. Common above-ground pests include aphids and cabbage loopers, which can be sprayed with high-efficiency imidacloprid solution. Underground pests include cutworms and wireworms, which can be controlled by spraying dichlorodiphenyltrichloroethane powder.
