The key points of field management during potato growth are: good irrigation, cultivating and weeding, topdressing and earth-cultivation in the early stage; paying attention to drainage and pest control in the later period; soil cultivation and pest control should be regarded as the top priorities of field management.
1. Check for missing seedlings. After the small seedlings are out of the field, they will be inspected and replanted to ensure that they are fully seedlings
2. Timely cultivating earth. When sowing, it is necessary to use light soil, and then combine cultivating and weeding to cultivate the soil. Generally, the soil is cultivated twice, and the last time before the plant is ridged and enclosed, it is necessary to combine the thick ditch with the ditch. Thick soil, soil temperature stability, can reduce the production of deformed tubers, but also prevent late blight of the blight from the lenticels intrusion into the tuber inside the disease caused by potato or rot.
3. Pick buds. At the beginning of flowering, the buds were removed to reduce nutrient consumption and increase production.
4. Reasonable fertilization. (1) Principle of fertilization: Potatoes are high-yielding crops and require more fertilizer. Among the three elements, potassium is the most, followed by nitrogen, and less phosphorus. Fertilization is mainly based on basal fertilizer supplemented by topdressing; basic fertilizer is applied again, and topdressing is applied early; farm manure is applied more, and nitrogen fertilizer is suitable. Nitrogen fertilizer application should not be applied blindly according to soil fertility. (2) Fertilization method: Apply soil testing and formula fertilization to achieve a reasonable mix of nitrogen, phosphorus, potassium, and trace elements. Base fertilizer: 2500-3000 kg high quality farmyard fertilizer per acre as base fertilizer; Seed fertilizer: 40-60 kg of special compound fertilizer for potato or 10-15 kg of urea per mu, 40 kg of calcium sulphate, potassium sulphate (KP used) 5 kg, Shi Yu Tang, mixed evenly, avoid burning seed; Topdressing: seedling height 10-15cm (after Qi Miao) combined with the first cultivator soil, according to the seedlings of Mushi urea 10-15 kg. In the bud stage, 10 kg of urea and 10 kg of potassium sulfate are applied in combination with the second cultivator.
5. Strengthen pest control. The selection of resistant (resistant) disease-resistant varieties; reasonable layout, implementation of crop rotation, promotion of interplanting with high-crop crops, clean the pastoral, strengthen the cultivator weeding, reduce the number of pests and diseases; cultivate disease-free and strong seedlings. When using pesticides, it is necessary to pay attention to the prohibition of the use of highly toxic, highly toxic, high-residue pesticides and their mixed pesticides that are prohibited by the State. 2 When using chemical pesticides, relevant standards of GB4286 and GB/T8321 should be implemented; for pesticide mixtures, the most safety interval is to be carried out. 3 Rationally mix, rotate and alternately use drugs to prevent and postpone the emergence and development of pest resistance.
