After the seedlings, seedlings, and seedlings are ready, the seedlings, seedlings, and seedlings should be checked in time. If there is a lack of seedlings, the seedlings should be replaced in time to ensure the entire seedlings. After Qi Miao, time and seedling. Weaken and stay strong when weeding, 4 to 5 seedlings per hole after the first seedling, and 3 seedlings per hole after the second seedling.
Cultivating the loose soil in the middle-cultivation soil makes the soil of the Potato layer loose and aeration, which is conducive to root growth, creeping stem extension and tuber expansion. Before emergence, if the soil is slab-bound, loosen the soil to facilitate emergence. After the seedlings were planted, the first plowing was carried out in time, with a depth of 8-10 cm, and combined with weeding. The second plowing was carried out 10 to 15 days after the first plowing, which should be slightly shallower. When cultivating the bud, the third plowing is shallower than the second plowing. Combined with soil cultivating, the thickness of the soil cultivating should not exceed 10 cm to thicken the potato layer, avoid exposing the potato pieces, and reduce the quality.
It takes a long time from sowing to emergence for top dressing potatoes at the right time. After emergence, it is necessary to apply sprouting fertilizer with clear manure water and a small amount of nitrogen fertilizer as early as possible to promote the rapid growth of seedlings. In the current bud period, the topping potato fertilizer is applied in combination with soil cultivation, mainly potassium fertilizer, combined with nitrogen fertilizer, and the amount of fertilizer depends on the growth of the plant. After flowering, fertilization is generally no longer used. If the phenomenon of defertilization and premature aging appears in the later period, foliar spraying can be carried out with phosphorus and potassium or in combination with trace elements.
Chemical control In the current bud period, use 15% paclobutrazol 35g per acre and add 60kg of water to evenly spray, which can prevent the potato plants from becoming too long, dwarf the plants, thicken the leaves, thicken the stems, and deepen the color of the leaves. Underground growth accelerates tuber expansion and increases yield.
Prevention and control of pests and diseases Do a good job in the prevention and treatment of late blight, viral diseases, and underground pests to ensure a high yield of potatoes.
