Detailed Explanation of Key Points for Autumn Potato Cultivation Techniques

Potato is a dish we relatively love to eat, and it can be cooked into delicious food in all kinds of ways. So are you clear about autumn potato cultivation techniques? Let's take a look!

Autumn Potato Cultivation Techniques

1. Timely sowing

In areas at an altitude of about 500 m, sowing from August 10 to 15 is suitable; in areas above 500 m altitude, sowing in early August is acceptable; in areas below 400 m altitude, sowing should be postponed to the end of August. Solanaceous crops should be avoided as the previous crop.

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

First soak the seed in 200-fold formalin solution for 2 hours to prevent bacterial wilt. The sprouting method is as follows: about 10 days before sowing, soak the seed in 10 ppm “920” solution for 15 minutes to break the dormancy period of the potato, then nurse the seed indoors with wet mud and sand, and keep the mud and sand moist; generally the seedlings will emerge uniformly. Sow after sprouting.

3. Reasonable close planting

Because autumn-planted potatoes have a growth period about 20 days shorter than spring-planted potatoes, their plant height is far lower than that of spring-planted ones, and the yield per plant is low, so reasonable close planting is necessary, generally about 5,000 plants per mu.

4. Fertilization and weeding

The growth period of autumn-sown potatoes is only about 70 days, so fertilization should be based mainly on base fertilizer, and dilute human manure and urine, pig and cattle pen manure, plant ash, and compound fertilizer can be used. After emergence, carry out intertillage and weeding, and apply nitrogen fertilizer as appropriate. After sowing and before emergence, 1,000-fold Henaies can be sprayed per mu to seal the soil and control weeds.
