Last Updated: 2024/11/22, 1. Preparation before sowing: in mid-February, prepare agricultural materials such as seed potatoes, pesticides, chemical fertilizers and agricultural films. Take the seed potatoes out of the basement and put them indoors at about 12 degrees Celsius to sprout. 2. Cut a good seed potato: make sure that each seed potato has at least 1 color 2 bud eyes and weighs about 30 grams. The chopped seed potato pieces were mixed with medicine. The formula of the powder is to add 250 grams of 70% methyl topiramate wettable powder with 50 kg of fossil powder. 3. Timely early sowing: generally sowing from March 5 to 15, row spacing 90 cm, plant

Left and right. The chopped seed potato pieces were mixed with medicine. The formula of the powder is to add 250 grams of 70% methyl topiramate wettable powder with 50 kg of fossil powder.

3. timely early sowing: generally sowing on March 5-15, with row spacing of 90 cm, plant spacing of 12 cm, sowing amount of 150kg per mu, and planting density of 5000 to 5200 plants per mu. Application per mu

Foot fertilizer: potassium sulfate compound fertilizer 50 kg, potassium sulfate 20 kg, diammonium 100 kg. Broadcast

Cover the film in time after planting.

4. Field management:

(1) timely film matting. After sowing, potatoes usually begin to emerge within 30 days of 25m / m.

At the same time, special personnel should be sent to inspect the field and find that the seedlings are unearthed and cut out the covered agricultural film in time, such as

If the film is not scratched in time, it is easy to cause the seedlings in the film to burn due to high temperature. There are 80% left in Jian Quan Tian.

Uncover all the agricultural film in time after the right seedling is unearthed.

(2) cultivate the soil by ploughing. After the emergence of the potato, the potato grows to about 8 mi 10 cm in the first place.

Secondary ploughing. The most suitable height of soil cultivation is 4ml / 5cm of exposed seedlings. At the budding stage, proceed with the first

Secondary ploughing to cultivate the soil.

(3) topdressing and watering. In the first intertillage, 20 kg of ammonium sulfate was applied per mu. This

In addition, it is necessary to timely pour good seedling protection water, budding water and potato expansion water.

(4) timely prevention and control of diseases and insect pests. In mid to late May, timely control of underground pests and spraying

Downy mildew blight net to prevent potato late blight. Timely control of aphids from the end of May to the beginning of June.
