1. Seeding period: from October to May of the following year can be sown, using protective or open field cultivation, hillside or dry land can be cultivated, but in the deep soil layer, irrigation and drainage of good sandy loam soil is better. Use 30 to 40 grams per 667 square meters.
2. Set time: leaf age 6-8 leaves.
3. Planting density: Plant spacing 40 cm 50 cm, 1 plant per hole.
4. Fertilizer and water management: Reapply basic fertilizer, increase phosphorus and potash fertilizer, apply 2500 to 5000 kg of farmland fertilizer per 667 square meters of farmland, 100 to 150 kg of phosphate fertilizer, and 20 to 25 kg of calcium sulfate in the field; Potassium sulfate applied 20 ~ 25 kg, urea 25 ~ 50 kg; harvesting every 7 days with 0.4% potassium dihydrogen phosphate, 0.6% urea, 0.1% borax and 0.1% zinc sulfate mixture for extra-root fertilizer.
5. Prevention and control of pepper virus disease: Pepper virus disease has four symptoms: mosaic, floralization, necrosis and malformation. The mosaic is divided into two types: light mosaic and heavy mosaic. The light mosaic leaves show a slight fading of the veins, or a thick, light green mottle. The diseased plants have no obvious deformities or dwarfs and do not cause fallen leaves. In addition to the appearance of faded mottled leaves, the heavy mosaic leaves are uneven, and the veins are shrunken and deformed, or linear leaves are formed. The growth is slow, the fruit is small, severely dwarfed, yellowed, the diseased leaves turn yellow, and defoliation occurs. The tissue becomes brown and necrotic, the plants are short, and there are many branches and branches. Sometimes several conditions appear in the same strain.
Control methods: (1) Seed treatment, using 10% trisodium phosphate soaking seeds for 20 to 30 minutes after washing germination. Spray 0.1%~0.2% zinc sulfate separately before splitting, before planting or during flowering. (2) Persisting in rotation with non-solanum crops, preferably with paddy-upland rotations, with a rotation period of not less than 3 years. (3) Spray 20% Virus A wettable powder 500 times and 1.5% Phytopathogenic Ling emulsion 1000 times. Spray it once every 10 days or so and spray it 3~4 times continuously. (4) Insect prevention and disease prevention, during the period from April to June, when locusts and cockroaches move into the pepper field, timely spray 20% dicofol 800-1500 times or 2.5% enemy-killed EC 5000 times to kill vector insects and reduce transmission. .
