First, timely cultivating potato buds, we must strengthen the cultivator, shallow adobe soil, implement high soil with cultivator, earth up to 15-20 cm.
2. Appropriate top-dressing shall apply nitrogen fertilizer to potato dwarf and yellow weak potato fields, apply 5 kg of urea per mu, and apply topdressing one by one; if the plant grows vigorously, phosphorus and potash fertilizers should be applied. Mushi phosphate fertilizer should be 15 kg. And plant ash, or 15-20 kg of compound fertilizer.
3. Immediately after the budding of the potato, it immediately enters the flowering stage and consumes a lot of nutrients. To avoid this inefficient consumption, it should be topped off and the buds should be removed.
Fourth, the root bud spraying period should be selected sunny afternoon afternoon to spray fertilizer, spraying 0.3% potassium dihydrogen phosphate and 0.3% manganese sulfate mixture, or 15% paclobutrazol wet powder 150 grams of water 15 kg, stirring After uniform spraying, spraying 50 kg of mu, the potato plants can be dwarfed by one-third, the leaf color can turn dark green, photosynthesis can be enhanced, and the proportion of large potatoes can be increased. Quantian spray a 0.3% -0.5% potassium permanganate solution, can prevent potato black stem disease, virus disease.
V. Prevention and control of pests and potatoes The potato has entered the budding stage, and the fields have been growing in a sheltered environment. The environment is prone to high humidity and causes epidemics. Once the central diseased plant should be sprayed and prevented, available copper sulfate, chlorothalonil, Rhizoctonia and other fungicides. Potatoes are also susceptible to damage by ladybugs, which can be eliminated by 800-fold spray of omethoate.
