Cultivation techniques of potato in autumn

1. Sowing seeds at the right time

It is appropriate for areas with an altitude of about 500 meters to sow seeds from August 10 to 15, areas above 500 meters above sea level can be sown in early August, and areas below 400 meters above sea level should be postponed to the end of August. The former crop of Solanaceae is taboo.

2. Do a good job of seed potato disinfection and sprouting

First soak the seeds with 200 times formaldehyde solution for 2 hours to prevent bacterial wilt. The method of sprouting is that about 10 days before sowing, soak the seeds with 10ppm's "920" solution for 15 minutes to break the dormancy period of potatoes, and then feed the seeds with wet sand indoors and keep the sediment humidity. Sow seeds after germination.

3. Reasonable close planting

Because the growth period of autumn potato is about 20 days shorter than that of spring potato, the plant height is much lower than that of spring potato, and the yield per plant is low, so it is necessary to plant about 5000 plants per mu.

4. Fertilization and weeding

The growing period of autumn sowing potato is only about 70 days, and fertilization should be based on base fertilizer, such as rare manure, pig and cattle pen fertilizer, plant ash and compound fertilizer, etc. After sowing, grass can be sealed with 1000 times spray per mu before seedling.
