How to manage growing potatoes?

How to manage growing potatoes? Please help to introduce the management methods of planting potatoes can refer to the following: (1) after checking the seedlings and replenishing the seedlings, check the seedlings in time, and replenish the seedlings in time if there are missing seedlings to ensure the whole seedling. The method of seedling replenishment is as follows: when sowing, the extra potato pieces are closely planted in the field to replenish the seedlings. When replenishing seedlings, if there is a diseased rotten potato in the hole, the diseased potato and its surrounding soil should be dug up first and then the seedlings should be replenished. When the soil is dry, the seedlings should be planted after digging holes and watering, combined with a small amount of fertilizer, so as to reduce the slow seedling time and restore growth as soon as possible. If there are no spare seedlings, the holes of multiple seedlings can be selected from the ridges and rows where the seedlings emerge in the field, and the excess seedlings can be broken off from the base of the sweet potato block and transplanted to replenish the seedlings. (2) the soil is loosened and aerated by ploughing and loosening the soil, which is beneficial to root growth, stolon elongation and tuber expansion. If the soil surface is hardened before emergence, the soil should be loosened to facilitate seedling emergence. After finishing the seedlings, the first intertillage was carried out in time, the depth was 8mur10 cm, and combined with weeding, the first intertillage was 10 murals for 15 days, and the second intertillage should be slightly shallow. When budding, the third intertillage is carried out, which is shallower than the second intertillage. And combined with soil cultivation, the soil thickness is not more than 10 cm, in order to thicken the tuber layer, avoid potato exposure and reduce the quality. (3) topdressing potato takes a long time from sowing to emergence. After emergence, it is necessary to apply bud fertilizer with clear manure water and a small amount of nitrogen fertilizer as soon as possible to promote the rapid growth of seedlings. In the bud stage, combined with soil cultivation, one-time topdressing of potato fertilizer, mainly potassium fertilizer, combined with nitrogen fertilizer, the amount of fertilizer depends on the growth and appearance of the plant. After flowering, generally no longer fertilize, if the late stage shows the phenomenon of premature senility, you can use phosphorus and potassium or combined with trace elements for foliar spraying. (4) there are many diseases to control diseases and insect pests, and the common diseases are virus disease, late blight, bacterial wilt, ring rot, scab, cancer and so on. Late blight mostly occurred in Rain Water in more seasons and around the flowering stage of the plant. Therefore, attention should be paid to the prevention and control of Bordeaux solution or Trichoderma as soon as possible. At present, chemical control of bacterial wilt is difficult, and the control methods are mainly through reasonable rotation, selection of disease-resistant varieties and small whole potato as seeds. The main pests of potato are ladybugs, soil silkworms, aphids, grubs, mole crickets and so on. Click to get more potato planting techniques click to get more vegetable planting techniques
