1, black plastic bag preservation method
First, put the potatoes in a cool and ventilated place, dry the water in the skin, then put them in a black plastic bag, put some napkins in the bag, and then put them in a carton. First of all, this method can avoid the photosynthesis of potatoes; The second is to dry the water in the potato skin in advance, and the napkins and cartons can absorb water to ensure that the environment around the potatoes is dry; So the potatoes preserved in this way will not germinate and turn black even if they are preserved for one year.
2. Dry sand burial method
Prepare some sand first, expose it to the sun for a day, collect it after drying, and let it cool for later use; Put all the potatoes in a pot or bucket, and then pour in the dry sand. This method can also avoid the photosynthesis of potatoes, and the sand is very dry after exposure, which can prevent potatoes from sprouting because of moisture, especially the particles of sand are very small, so the temperature of potatoes is relatively constant after being covered with sand.
3, salt water bubble rub method
Clean up the sediment on the potato skin first, then pour half a basin of clear water into the basin, then pour half a bag of salt, stir well, then put the potato in salt water for 10 minute, then take it out and drain it, and then take it to a cool and ventilated place to dry! Then put the potatoes in a cardboard box and put them in the shade, so that the potatoes will not breed bacteria and can be preserved for a long time.
Potato planting skills
Planting potatoes needs to choose soil with loose soil, good air permeability and good drainage, and an appropriate amount of base fertilizer can be added to the soil. Choose a good variety of potatoes and cut them into slices to ensure that each slice has 3-4 buds. If the weather is dry after potato sowing, it should be irrigated in time to ensure the emergence of seedlings; There should be enough water in the growth period and flowering period; Water should be properly controlled in the early stage of potato production, with little or no watering.
Potatoes should be irrigated in time according to the weather and soil moisture when the tubers grow to 2-3cm; In the late stage of potato production and before harvest, it is necessary to control water, avoid watering and prevent diseases and rotten potatoes. Potato chips need to be dipped in plant ash, then planted in the soil, covered with thin soil and watered with appropriate amount of water to keep the soil moist.
