Last Updated: 2024/11/06, Grasping the field management in autumn and winter is the key technology to obtain high yield of autumn potato. The specific measures are as follows: 1. Timely ploughing and weeding, seedling topdressing: because the sunshine in autumn is short, which is suitable for tuber growth, the plant is early and not easy to grow. Therefore, promotion should be given priority to in management. When potato seedlings are 60-70%, urea 2.5-3 kg / mu, water and fertilizer 1600-2000 kg / mu, plant ash 500 kg / mu and human urine 40-50 kg / mu are used when growing to 30-40 cm.

Field management in autumn and winter is the key technology to obtain high yield of autumn potato. The specific measures are as follows:

1. Timely ploughing, weeding, seedling topdressing: because the sunshine in autumn is short, which is suitable for tuber growth, the plant tubers are early and not easy to grow, so promotion should be given priority to in management. When potato seedlings are 60-70%, urea 2.5-kilogram per mu, water and fertilizer 1600-2000 kg per mu are applied; when growing to 30-40 cm, 500 kg of plant ash per mu and 40 kg of urine to human and livestock are used to mix well and cultivate soil in base compartments. to promote early growth and rapid growth.

2. Clear the drainage ditch and reduce the humidity in the field: continuous watering should be carried out after sowing, keeping the ridge moist until seedling emergence. When the temperature decreases in the later stage, we should reduce irrigation, clean up drainage and wet ditches, and gradually thicken the soil to prevent cold and protect tubers.

3. Timely use of medicine to control potato late blight and aphids: the most effective agent to control late blight is 600 times of 25% Ruidu Manganese Zinc solution, or 72% Klu 700 times solution spray; the effective agent to control aphids should be pirimicarb 2000-3000 times liquid spray
