High-yielding cultivation techniques of Potato with Rice Straw

1. Select varieties

The varieties of fresh potato vegetables are Zihua 851, Zhongshu 3, Fewurita and so on.

2. Prepare the land and make beds.

Soil selection: potato can adapt to a wide range of soil, sand and mud can be cultivated. But choose loose soil, good drainage, PH5.5-6.5 slightly acidic sandy soil. Potato belongs to Solanaceae, so it is not allowed to be cropped continuously or centrally mixed with other Solanaceae crops.

Small high ridge soil preparation: after harvesting, use a rotary tiller to break the soil, and then use a border preparation machine to set up ridges with a width of 110 Mel 120 cm, a ridge height of 30-40 cm, a ridge width of 70 mi 80 cm, and a furrow width of 20 mi 25 cm between the two ridges. After the ridging machine ridges, and then manually use hoes to fine adjust the bed, to achieve fine crushing, neatness.

3. Seed potato treatment

Selected seed potato: the dormancy period of seed potato is not broken, resulting in irregular germination after sowing, low emergence rate and long emergence time. Seed potatoes should be strictly selected and diseased and rotten potatoes should be eliminated. The healthy seed potato has young potato pieces with complete potato pieces, no diseases and insect pests, no injury and freezing, smooth potato skin and fresh color. The cracked epidermis, deformities, deformities, tips, diseased spots, frozen stiff and degraded tubers should all be eliminated.

Seed potato chips: larger seed potatoes need to be cut into several pieces before sowing, and small potatoes should also be cut where there are no teeth, because after cutting, oxygen can enter the potato smoothly from the incision, thus accelerating the activity of enzymes, breaking dormancy, and promoting neat germination. The size of the cut piece should be 20 g-25 g small seed potato, and it should be inclined or cut to the top according to the order of tooth eye arrangement from the navel (pay attention to not hurting the tooth eye), so that there are top teeth on each seed potato.

Seed potato disinfection: when cutting seed potatoes, a basin of disinfectant (0.1% potassium permanganate or 75% alcohol or 0.5% formalin solution) should be placed next to it. For each seed potato cut, the knife should be disinfected once. After cutting the seed potato, soak the cut seed potato in 0.5% formalin solution for 20 minutes for 30 minutes, then put the seed potato into a pile and cover it with thin film.
